Description

Microwave synergistic photocatalytic wastewater degradation reactor with enhanced catalytic particle interception

technical field

The invention relates to a microwave synergistic photocatalytic wastewater degradation reactor that strengthens the interception of catalyst particles, and belongs to the technical field of CO2F wastewater treatment.

Background technique

Microwave photocatalytic degradation treatment technology, as an effective harmless treatment technology for industrial wastewater containing organic pollutants, has attracted much attention in recent years.

Regarding the microwave photocatalytic degradation technology, as an example, refer to the Chinese patent application with publication number CN102260003A.

The Chinese patent application with the publication number CN102260003A uses microwaves as the excitation source to excite the electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiates the suspension mixed with photocatalyst titanium dioxide inside the liquid. The electrodeless ultraviolet lamp is shrouded and protected by a quartz tube. , an air pump continuously injects air into the inner chamber of the quartz tube, and the air overflowing from the quartz chamber communicates with the microporous aeration head at the bottom of the reactor through the pipe. The upper area is the microwave photocatalytic reaction zone. This scheme also uses the built-in membrane separation module of the reactor to extract the purified water, and uses the membrane separation module to realize the interception and reuse of the photocatalyst titanium dioxide particles; A partition is set up between the electrodeless ultraviolet light source and the membrane separation module to prevent ultraviolet rays from damaging the organic matter membrane separation module; part of the air that passes into the reactor directly participates in the photocatalytic degradation reaction relying on the photocatalyst titanium dioxide, and Part of the air, under the direct irradiation of ultraviolet light, generates a certain amount of ozone, which of course also plays a direct role in the oxidation and degradation of organic pollutants.

The Chinese patent application with the publication number CN102260003A has undoubtedly played a non-negligible role in promoting the progress of microwave photocatalytic wastewater degradation technology, and the work carried out by its researchers in this field is admirable.

Based on sincere admiration and common direction of efforts, what we are going to talk about next is the problem.

There are fourteen questions to be discussed below; the fourteen questions are parallel fourteen questions; the order of their order is only for the convenience of discussion.

One of the problems:

The Chinese patent application with the publication number CN102260003A, the membrane separation assembly used to intercept catalyst titanium dioxide particles is placed in the inner cavity of the reactor, immersed in the liquid to be treated, and relies on rising ozone-containing bubbles to flush the membrane separation assembly , so as to remove the catalyst particles adsorbed and retained on its surface, so as to achieve the purpose of recycling and reusing the catalyst particles. At the same time, the membrane separation module also relies on this method to self-clean and maintain its separation ability. Then, based on this structure, only Commercial curtain-type hollow fiber membrane modules or flat-panel membrane modules, and the membrane separation module needs to be immersed in a strong oxidative surrounding environment where ozone bubbles rise, so there must be requirements for the oxidation resistance of the membrane separation module , the organic membrane separation module made of ordinary materials cannot withstand such a use environment, so the membrane separation module made of PVDF can only be used, which has been clearly stated in paragraph 0009 of the public document of the case and item 3; The material cost of the filter membrane that requires special oxidation tolerance is relatively high, and its market price is of course higher than that of ordinary organic microfiltration membrane components without oxidation tolerance requirements; in other words, the structure of the case leads to membrane The material of the separation components is limited to the more expensive PVDF material. In addition, the possible ultraviolet light leakage in the device may touch the organic membrane module, which also requires the material of the organic membrane module in the device to be able to resist ultraviolet radiation. From this point of view, based on the structural scheme of the device, the organic membrane separation module The material can only be limited to the more expensive PVDF material.

Compared with ceramic filter components, organic membrane components have obvious advantages; this point is well known to those skilled in filtration technology, and will not be repeated here.

So, under the premise of using organic material membrane modules, can we get rid of the limitations of this PVDF membrane material? This is a problem that needs to be solved, this is one of the problems.

Question two:

In view of the relatively weak scouring force and cleaning ability of the rising air bubbles, the pore diameter of the membrane separation module used in conjunction with this cleaning method can only be selected from relatively large microfiltration grade filter pore diameters. It is 0.1-0.2 microns. On this point, it is also clearly defined in paragraph 0009 of the public text of the case and claim 3. The pore size of this kind of filter is limited. From the selection, built-in In addition, it is inevitable in terms of the method of soaking and the self-cleaning method of rising bubbles, and the pore size of the filter can only be limited to the microfiltration level. In other words, the scouring and cleaning power of this method of scouring with rising bubbles is too weak to deal with the filter membrane with a smaller pore size. Therefore, in the device in this case, the pore size of the filter membrane is limited to 0.1 micron- Between 0.2 microns is an inevitable choice without room for negotiation.

The so-called filter pore size of 0.1-0.2 microns, if you change the measurement unit, corresponds to the filter pore size of 100-200 nanometers; what is that concept? In terms of its lower limit of 100 nanometer filter pore size, the size of the catalyst particles it can intercept must be above 100 nanometers, and catalyst particles smaller than 100 nanometers cannot be intercepted; in other words, catalyst particles smaller than 100 nanometers The particles will directly penetrate and pass through the filter pores of the membrane module and mix into the so-called clean water output from the degradation reactor.

Now we need to talk about the particle size of the photocatalyst involved in the ultraviolet photocatalytic degradation reaction and the selection of the photocatalyst dosage form.

Professionals engaged in photocatalytic degradation research know that the photochemical degradation reaction stimulated by ultraviolet light mostly uses titanium dioxide particulate catalyst as the catalyst; at present, a wide variety of photodegradation agents based on the photocatalytic properties of titanium dioxide have been developed at the laboratory level. Microparticle catalysts, of course, the photodegradation catalysts formed by these different preparation methods have various particle sizes; the photocatalysts made by different preparation methods have a particle size as small as 20 nanometers, as large as 100,000 nanometers, that is, 100 microns. , among them there is no shortage of photocatalyst varieties with excellent performance; however, due to the constraints of long-term performance stability evaluation, preparation cost, market expansion and other factors, the supply capacity of most of the photocatalysts is limited to the laboratory level, while There is no large-scale commercial production level; the commercially available photocatalyst that can be purchased in large quantities and can be used in large quantities for ultraviolet light is the famous gas phase titanium dioxide P25; the specific technical meaning of gas phase titanium dioxide P25, People in the industry know that they will not go into details here; the average particle size of fumed titanium dioxide P25 is 21 nanometers; the performance of fumed titanium dioxide P25 is not optimal, but its performance is stable, the key is that it can be purchased in large quantities in the market, and can be purchased in It is widely used on an industrial scale. Therefore, P25 catalysts are often used in professional photocatalytic laboratories as a reference or comparison pointer to measure the catalytic performance of various self-made photocatalysts. In fact, in view of the characteristics of ultraviolet photocatalytic degradation reactions, the degree of dispersion The higher the photocatalyst, the more suitable it is for this type of reaction, that is to say, the photocatalyst with an average particle size of about 21 nanometers can provide catalyst interface area, anti-sedimentation ability, long-term stability of catalytic performance, etc. , on the whole, is the most ideal. To put it simply, at present, the photocatalysts that are cheap and good, and can be purchased and used in large quantities in the commercially available commercial grade in the ultraviolet light band are the gas-phase titanium dioxide P25 catalysts with an average particle size of 21 nanometers; the application on an industrial scale At the level, this photocatalyst with an average particle size of 21 nanometers is the de facto first choice.

As mentioned above, the Chinese patent application with the publication number CN102260003A is used to intercept the photocatalyst membrane assembly, which is to peel off the catalyst particles adsorbed and deposited on the surface of the membrane assembly by scouring the rising bubbles. However, this kind The scouring force and cleaning force are too weak to cope with the filter membrane with smaller pore size in the way of rising bubble scouring. Therefore, in this case, the pore size of the filter membrane is limited to between 0.1 micron and 0.2 micron. Filter pore level, to change the unit of measurement, in this case device, the filter membrane pore size is limited to the microfiltration filter pore level between 100nm and 200nm, which is an inevitable choice without room for negotiation; there is no choice in this case Of course, the microfiltration filter holes between 100 nanometers and 200 nanometers cannot intercept the above-mentioned fumed titanium dioxide P25 particles with an average particle size of 21 nanometers; In the purified water, secondary pollution is formed, which of course also causes serious loss of the catalyst and can no longer be used; The wall collision will inevitably produce a large number of small particle size fragments, among which the particle size is less than 100 nanometers, which cannot be intercepted by the microfiltration filter holes between 100 nanometers and 200 nanometers, and these small fragments will also pass through its membrane. Components enter the so-called clean water, causing secondary pollution.

It can be seen that in the Chinese patent application with the publication number CN102260003A, the interception structure scheme for photocatalyst particles and the cleaning scheme for related membrane modules are not ideal.

Therefore, how to achieve fine interception and recycling of photocatalyst particles on the premise of incorporating the advantages of this case is an important topic worth pondering, and this is the second question.

Question 3:

We know that the liquid water itself can also absorb microwave energy and cause the temperature rise effect of the treated liquid water itself, but this temperature rise effect accompanying the wastewater treatment process is not what we expect. In other words, the microwave energy from the magnetron is not completely used to excite the electrodeless ultraviolet lamp, but a considerable part of the microwave energy that should only be used to excite the electrodeless ultraviolet lamp is dissipated due to the temperature rise effect. The unwelcome temperature rise effect has caused unnecessary waste of microwave energy. In view of the device structure scheme shown in the above-mentioned Chinese patent application with the publication number CN102260003A, the only reasonable way is to reduce the microwave photocatalytic reactor. In other words, the volume of the single tank is reduced to achieve the purpose of weakening the redundant dissipation of microwaves. Regarding this point, in the specific implementation of the CN102260003A application, the appropriate size of the overall structure of the device is clearly expressed, and the expressed The preferred size corresponds to a device with a very small shape. In this way, the distance between the inner wall of the reactor and the microwave radiation source is small, the amount of waste water in contact with the microwave is small, and the microwave energy absorbed by the waste water is relatively small. Correspondingly, the waste water treatment capacity of a single tank is therefore also small. More specifically, the internal volume corresponding to the suitable size of the device expressed in its embodiment is 40 liters, that is, the waste water treatment capacity of a single tank is 40 liters. liter, that is, 0.04 cubic meters. In other words, its one-time full-scale operation only solves 0.04 cubic meters of industrial wastewater. Then, it is necessary to repeat the whole set of operations many times from the beginning to the end. The meaning of industrial scale, for example, is just a rough example. The preferred structural size of this case roughly corresponds to a wastewater treatment capacity of 0.04 cubic meters in a single tank, which needs to be repeated 1,000 times from the beginning to the end. Its accumulative volume can only reach 40 cubic meters of waste water with an industrial level. Such excessively cumbersome repeated operations will lead to serious waste of manpower and material resources. It can be seen that the actual waste water degradation treatment of this kind of scheme shown by CN102260003A Efficiency may not be as good as desired. Therefore, under the premise of not causing more waste of microwave energy or reducing the waste of microwave energy, how to increase the wastewater treatment capacity of a single tank and reduce the unnecessary number of repeated operations from the beginning to the end of the intermittent wastewater treatment device, Improving its wastewater treatment efficiency is a meaningful technical issue worthy of attention.

On the other hand, according to literature reports, some systems, in the case of microwave direct irradiation of wastewater liquid, photochemical catalytic degradation efficiency is indeed improved, that is to say, in some systems, microwave direct irradiation of wastewater liquid and photochemical catalytic There is a certain coupling effect between degradation.

Therefore, how to improve the treatment efficiency of the wastewater degradation device under the premise of taking into account the coupling effect is worth discussing, which is the third problem.

Question 4:

This kind of scheme shown by CN102260003A, its reaction tank interior diffuses the rising bubble, contributes slightly to the relatively large-scale circulation motion of the liquid inside the reaction tank; certainly, this deficiency is as specific to the CN102260003A scheme What is articulated in the implementation actually has little observable effect for small size, low capacity devices. From the perspective of industrial-scale application requirements, small-sized devices that cannot expand the processing capacity are of course not very attractive; then, as a possibility, if there is a way to achieve a large expansion of processing capacity, in this case, The importance of the relatively large-scale circulation of the liquid inside the reaction tank will naturally be highlighted; imagine the possibility of a large expansion of the processing capacity, then how to strengthen the relatively large-scale circulation of the liquid inside the reaction tank, of course That's a problem, and this is the fourth problem.

Question five:

For the photochemical catalytic oxidation reaction in the ultraviolet band, the following factors will affect the efficiency of the oxidation reaction, one is the wavelength and intensity of ultraviolet light, and the other is the particle size of the photocatalyst and the reaction solution per unit volume. The amount of photocatalyst used in the medium, the catalytic performance of the photocatalyst itself, etc., the third is the concentration of organic matter in the water body, the difficulty of oxidation determined by the molecular structure of the organic matter, etc., and the fourth is the oxygen atmosphere The degree of adequacy of the oxygen atmosphere, under other conditions being the same, the degree of adequacy of the oxygen atmosphere will become a decisive factor affecting the ability of photochemical catalytic oxidation degradation.

As shown in the scheme of CN102260003A, the numerous microporous aeration heads placed in the lower part of the reactor cavity are distributed on the bottom, and by means of the so-called water distribution plate, the arrangement of the microporous aeration heads is diffused. The effect becomes even worse. Of course, this does have its favorable side for the situation of using relatively easy-to-settling large-particle micron-scale photocatalysts. However, from the other side, this microporous aeration head In the way of diffuse arrangement, the supply of oxygen atmosphere is too scattered, but in fact the area most in need of enhanced oxygen supply is the most effective area of photochemical catalytic oxidation. Since the effective penetration depth of short-wave ultraviolet rays in liquid water is only about 20 cm, Therefore, the effective area that needs to strengthen the oxygen supply to promote the process of photochemical catalytic oxidation is actually the area within about 20 cm around the quartz tube, in other words, the area within about 20 cm around the quartz tube is the area that really needs Strengthen the area where the oxygen atmosphere supply is guaranteed. The stronger the oxygen atmosphere supply in this area, the faster the oxidation reaction will proceed; especially, the use of microwave excitation to generate infinite ultraviolet emission is characterized by high power and high intensity. , this is the strong point of the electrodeless ultraviolet lamp. However, because of the high power and high intensity of its ultraviolet radiation, it needs to be matched with a strong oxygen atmosphere supply capacity, otherwise, the strong ultraviolet radiation capacity will be It really is mostly wasted. As mentioned above, in the scheme shown in CN102260003A, many factors limit its reactor size and limit its actual processing capacity. As clearly shown in its specific examples, it can only be a single tank A small reactor with a single treatment volume of only about 40 liters, in the case of such a small reactor and small inner cavity, because the size itself is very small, then it lacks in the concentration of oxygen supply in the effective area of photochemical catalytic oxidation , it will not be so obvious, it can even be ignored, and it can even be regarded as a problem that does not exist at all. In the face of such a small-sized small reactor, the problem of lack of concentration of oxygen supply is not at all It may come to mind; however, imagine that if the above-mentioned many limiting factors can be overcome, and if there is a way to actually build a large-scale, large-capacity reactor, then the problem of strengthening the oxygen supply in the effective area within a distance of 20 cm around the above-mentioned quartz tube It will be highlighted, especially for the situation of using an electrodeless ultraviolet lamp as an ultraviolet radiation source, the problem of strengthening the oxygen supply in the effective area within a distance of 20 cm around the above-mentioned quartz tube cannot be ignored. In the construction of the reactor, enhancing the concentration of oxygen supply in the effective area and improving the efficiency of the wastewater degradation equipment is a problem that needs to be focused on, and this is the fifth problem.

Question six:

The CN102260003A scheme pumps air into the quartz tube containing the electrodeless ultraviolet lamp to achieve the purpose of ventilation, cooling and cooling of the electrodeless ultraviolet lamp, and the air flowing through the quartz tube will be partially transformed due to the irradiation of ultraviolet rays. Therefore, the air flowing out of the quartz tube is of course air containing some ozone. This scheme transmits the ozone-containing air to the microporous aeration head located below the reactor, and releases it from the microporous aeration head. During the bottom-up rise of these ozone-containing bubbles, the ozone contained in it will encounter the organic molecules encountered in the journey and undergo a redox reaction. Of course, this redox reaction will consume part of the ozone. There is no doubt about it. However, as mentioned above, as the scheme shown in CN102260003A, many factors that cannot be ignored inevitably limit its reactor size and limit its actual processing capacity, as clearly shown in its specific examples As indicated, it can only be a small reactor with a single treatment capacity of only about 40 liters in a single tank. In the case of such a small reactor and a small inner cavity, because the overall size itself is very small, then its reaction The longitudinal size of the inner cavity of the device or the depth of filling the liquid can only be a very small size. As clearly shown in its specific implementation, this size is only about 40 centimeters, and the depth of filling the liquid is only about 40 centimeters. 40 centimeters, in fact, the depth of the liquid is of course smaller than this number, so it is analyzed based on the depth of the liquid of 40 cm. Then, what is the concept of the depth of the liquid of 40 cm? That is to say, the path of the ozone-containing air rising through the wastewater is only a short 40 cm. This path is too short, and the ozone-containing air bubbles quickly pass through the water body that is only 40 cm deep. The contact time with the water body is too short. Only a small part of the contained ozone can be used to oxidize and degrade organic matter, while most of the ozone simply passes through the liquid, escapes from the liquid surface and is emptied through the exhaust outlet. Simply put, Most of the oxidation potential of these ozone is wasted, and the escaped and wasted ozone will actually cause unnecessary air pollution; Ozone-containing air is injected into a water storage tank with a depth of one meter. When the water depth reaches one meter, the smell of ozone can still be clearly smelled near the water surface. It can be seen that the liquid depth of 40 cm is obviously not enough. Complete utilization of ozone; it can be seen that for the type of equipment such as infinite ultraviolet photochemical catalytic wastewater degradation reactor, the problem of incomplete utilization of ozone also needs attention. Obviously, people expect more complete utilization of ozone and more polluting exhaust emissions. There are few infinite ultraviolet wastewater degradation reactors, which is the sixth problem.

Question seven:

The operation of the wastewater catalytic degradation reactor needs to consume energy. Therefore, the operator will definitely hope that when the wastewater degradation reaction reaches the end, it can be impartial, neither too early nor too late to stop the continuous injection into the reactor. Energy; if the time to stop injecting energy is too early, the degradation of wastewater will not be complete; and if the end of the reaction has already been reached, but still continue to inject energy into the reactor, it is undoubtedly a waste of precious energy. The structure of CN102260003A scheme as the technical background of this case can not give any instant information to the end point of waste water degradation, so, just can only rely on experience to estimate the end point of waste water degradation reaction; And rely on experience to estimate the end point of waste water degradation reaction, then It is obviously unsatisfactory; then, how to make an immediate information output that is neither advanced nor delayed for the end point of the wastewater degradation reaction, and immediately shut down the energy input to the reactor at just the right moment is a technical threshold that cannot be ignored , this is the seventh question.

Question Eight:

The industrial wastewater subjected to microwave photocatalytic degradation treatment is inevitably mixed with some metal particles and carbon particles derived from the wear process of the mechanical system. Even if the amount is small, its existence is almost unavoidable. The organic matter membrane separation module in the patent application is installed in the microwave photocatalytic reaction area, and the partition plate for blocking ultraviolet rays installed between the quartz tube and the membrane separation module cannot block the microwave, so the microwave The actual action area must cover the installation area of the organic matter membrane separation module mentioned in the scheme. Based on the working mechanism of the membrane separation module, the deposition process of the above-mentioned metal particles and carbon particles on the surface of the organic matter of the membrane separation module It is unavoidable, and such particles such as metal particles and carbon particles are just good absorbing media for microwave energy, and particles such as metal particles and carbon particles that have absorbed microwave energy in a precipitated state will naturally The surface layer of the organic membrane separation module that is closely attached to it produces continuous penetration damage based on the thermal penetration mechanism. As mentioned above, due to the structure of the device in the CN102260003A application, only polyvinylidene fluoride membrane materials can be used. The temperature resistance of vinyl fluoride film is about 140 degrees Celsius, which is indeed much higher than that of ordinary film materials. However, the metal particles and carbon particles in the deposited state that have absorbed microwave energy have a point-shaped hole-like heat penetration. Corrosion is very easy to break through the temperature-resistant temperature limit of the polyvinylidene fluoride membrane. Due to the above reasons, it is conceivable that the actual service life of the PVDF membrane in the device of the CN102260003A application will be much lower than the expected ideal service life, the structure of the device in the CN102260003A application determines that under the framework of this structure, the above-mentioned point-like penetration-type thermal penetration damage problem cannot be avoided; therefore, how to bypass the point-like penetration-type thermal penetration damage Questions also need to be considered, this is the eighth question.

Question nine:

The Chinese patent application whose publication number is CN102260003A has a limitation on the particle size range of the catalyst applicable to its device, and the particle size range is limited to 20 nanometers to 100 microns. We know that in some cases where the pH value is not pre-adjusted in place and the pH value is inappropriate, titanium dioxide particles are prone to agglomeration, which will affect its effective working interface area and affect its photocatalytic performance; especially for particles in this particle size range Those sections with relatively small particle sizes are more prone to agglomeration problems caused by improper pH value pre-adjustment and inappropriate pH value; for this kind of catalyst particle agglomeration, effective measures must be taken immediately to carry out Aiming at the disaggregation operation of aggregates; however, in the CN102260003A scheme, we have not seen any structure that helps to resolve this problem immediately or a proposal that can immediately resolve this problem. For the reactor that can only be a small-sized structure due to many factors such as the CN102260003A scheme, it is still possible to directly lift the reactor manually, pour it over and inspect and handle the above-mentioned agglomeration situation outside the reactor, so if it is possible to expand its Capacity, just as a metaphor, if it is a large reactor or a giant reactor with several cubic meters to tens of cubic meters, it is obviously not a problem that can be solved by manual dumping. How to realize immediate in-situ disposal is a technical problem, and this is the ninth problem.

Question ten:

In the device structure expressed in the Chinese patent application with the publication number CN102260003A, the outer wall of the quartz tube used to screen the electrodeless ultraviolet lamp refers to the outer wall of the quartz tube, which is treated with the treated industrial wastewater for a long time. Contact, it is inevitable to gradually accumulate fouling. Of course, the fouling substances are mainly inorganic impurities that are not easily touched by the photocatalytic reaction. The fouling phenomenon formed by this mechanism is easy to be observed after the equipment has been running for a long time; Although the fouling layer on the outer wall of the quartz tube is only a thin layer, it is enough to significantly block the ultraviolet radiation of the electrodeless ultraviolet lamp, which will cause the actual treatment efficiency of the microwave photocatalytic reaction treatment device to be greatly reduced; The rising air bubbles in the reactor are too scattered and the flushing force is weak. It is really difficult to maintain the surface of the quartz tube by relying on the relatively dispersed air bubbles. In other words, the more dispersed air bubbles are more The weak scouring force is not enough to completely stop the fouling process on the surface of the quartz tube; during the use of the laboratory scale, the above-mentioned fouling problem is not easy to detect, but, on the industrial application scale, the fouling problem will undoubtedly be eliminated. Therefore, how to immediately and effectively remove the fouling layer on the outer wall of the quartz tube without dismantling the machine, and maintain the continuous high efficiency of the microwave photocatalytic treatment device, this problem cannot be ignored. Question ten.

Question Eleven:

This problem is the problem derived from the ninth problem mentioned above. As mentioned earlier, when some pH values are not pre-adjusted in place and the pH value is not appropriate, titanium dioxide particles are prone to agglomeration, which in turn affects its effective working interface area and its photocatalytic performance; especially for the CN102260003A proposal Those relatively small particle size sections in the applicable catalyst particle size range are more prone to agglomeration problems caused by improper pH value pre-adjustment and improper pH value; for this kind of catalyst particle agglomeration , it is necessary to take effective measures immediately to carry out the deagglomeration operation for the agglomerates; based on the structure of the CN102260003A scheme, the operator cannot immediately detect the agglomeration inside the reactor, and thus cannot make immediate disposal, thus , the limited effectiveness of reactors that are limited by many factors and can only be small-scale structures will be further reduced; therefore, in the application and operation of reactors, especially, for example, in possible large reactors or giant reactions In the application and operation of reactors, how to instantly perceive the main parameters that cause catalyst particles to agglomerate inside the reactor is a key issue, and this is the eleventh issue.

Question 12:

Based on the structure of this CN102260003A scheme, due to the limitations of the many factors already mentioned, its reactor can only be a small-sized reactor with a relatively small processing capacity, and the available size of the reactor inner cavity is certainly smaller, and the reactor inner cavity The height of the space that can be used to install the curtain membrane module in its structure is only about 30 cm. In this way, even if only a small curtain membrane module is used, it can only be reacted with plugs on the upper and lower ends. In the inside of the reactor, due to the small processing capacity and small size of the reactor, after the completion of the degradation reaction, the curtain membrane module is inevitably exposed to the air under the condition that the liquid is discharged from the inside to the outside, although the time of each exposure It may not be long, but the cumulative result of frequent tossing is that the curtain membrane module is in contact with the air too much. The normal use requirement of the curtain membrane module is to use it in a completely submerged state, that is to say, it must be In wet use, if the curtain membrane module is in contact with the air too much, it will age faster and its performance will decay faster, and the curtain membrane module is in contact with the air too much, in the CN102260003A proposal Under its structure, it cannot be avoided; therefore, how to protect the membrane module used to intercept the catalyst so that it can be used under normal working conditions, so that it can avoid excessive contact with the air, so as to maintain its normal performance and ensure Its normal service life is a problem that needs to be faced squarely, and this is the twelfth problem.

Question Thirteen:

Based on the structure of the CN102260003A scheme, during its operation, a part of the catalyst particles intercepted by the curtain membrane module is deposited on the surface of the curtain membrane module, and the other part is retained in the liquid phase, thus resulting in a The concentration of catalyst particles gradually increases with the gradual decrease of the volume of the liquid phase. For the subsequent membrane separation, the membrane separation load will also gradually increase. The problem of the large difference before and after the membrane separation load requires Solved, this is problem thirteen.

Question Fourteen:

Based on the structure of the CN102260003A scheme, during its operation, the water pump that fills the reactor cavity with waste water cannot judge whether the water level inside the reactor is high or low, and the operator can only rely on experience or visual inspection to turn off the water pump that fills the waste water in time Motor, if the experience is wrong or the visual response is not timely enough, it is easy to overflow the reactor due to excessive filling of waste water, which will cause unnecessary trouble; The membrane module pumps water outward. Without knowing the water level inside the reactor, the timing of shutting down the pump can only be judged based on experience or visual inspection. This operation is obviously unreliable, and it is very easy to make mistakes due to experience or visual inspection. If the response is not timely, the water pump cannot be shut down in time, and this kind of dry pumping and idling can easily cause the motor of the water pump to burn out. This problem cannot be ignored. This is the fourteenth problem.

Using the device of this case, the ozone-containing air bubble flow bubbled up from the bottom of the container, together with the waste water liquid dragged by it, enters the outer wall of the quartz tube through the lower metal mesh under the guidance of the cylindrical member. In the area between the surrounding boundary of the cylindrical space, the wastewater mixed with photocatalyst titanium dioxide particles and ozone-containing air participate in the microwave excitation and assisted photochemical catalytic oxidation degradation in this area, and are subject to certain degradation effects. Afterwards, the waste water can be sprayed out through the upper piece of metal mesh, and then spread to the surroundings and settle down. In this way, the degradation is carried out cyclically, reciprocatingly and automatically until the entire container inside is degraded. All waste water has reached the degradation index.

In the device of this case, a microwave zero irradiation area or a microwave weak irradiation area is formed in the area between the cylindrical space and the inner wall of the container, which does not belong to the direct photochemical and microwave coupling catalytic degradation.

How the volume of the region expands is all allowed; Based on this, the structure of the device in this case allows the single-tank design processing capacity of the described reactor to be greatly expanded, and the volume of the reactor is allowed to be greatly expanded. Of course, through the This is achieved by limiting the microwave irradiation airspace by using the surrounding boundary of the cylindrical space, and greatly expanding the design volume of the microwave zero irradiation area or the microwave weak irradiation area between the cylindrical space, the surrounding boundary and the inner wall of the reactor.

A second booster pump can be further installed on the connecting pipeline between the water outlet of the backwash hollow fiber membrane microfiltration filter and the water inlet of the backwash hollow fiber membrane ultrafiltration filter. Two booster pumps are used to supplement the water pressure to meet the water inlet pressure requirement of the backwash type hollow fiber membrane ultrafiltration filter; the second booster pump is not necessary.

The structure of the device in this case can also include some accessories, such as: a cooling water circulation system or an air cooling system connected with the magnetron cooling pipeline; Fixing bracket; said accessory is also for example a support member for carrying out suspended positioning of the cylindrical member in said container; said accessory may of course also include carrying out suspended positioning of said quartz tube in said cylindrical space The bracket or fixing frame or hanger; the accessories are also for example the filter installed at the wastewater inlet end of the reactor for intercepting impurities, and so on.

The advantage of the present invention is that the electrodeless ultraviolet lamp and the quartz tube used for screen protection are covered by a cylindrical member made of metal and two pieces of the metal mesh. This structure simultaneously restricts the action space of microwaves. The air space between the surrounding boundary of the cylindrical space forms a wastewater degradation reaction area assisted by microwave excitation and photochemical catalysis, and the multi-hole or multi-mesh structure of the two metal meshes does not affect the waste water. And the ozone-containing air bubble flow bubbling upwards freely enters and exits the airspace; and the airspace between the surrounding boundary of the cylindrical space and the inner wall of the container is a microwave zero-irradiation airspace or a microwave weak-irradiation airspace , the simple thermal absorption of microwave by the wastewater body is contained, thereby greatly weakening the useless dissipation of microwave energy; by greatly expanding the design volume of the microwave zero-irradiation airspace or microwave weak-irradiation airspace, the single-tank reaction can be realized The large expansion of the volume of the reactor allows the single-tank wastewater treatment capacity of the reactor to be greatly increased, and there is no need to worry about excessive dissipation of microwave energy in the unhelpful effect of increasing the temperature of the wastewater.

Based on the structure of this case, the design volume of the reactor, that is, the wastewater treatment capacity of a single tank, can be expanded to several cubic meters to dozens of cubic meters; based on the structure of this case, the frequency of a complete set of operations can be greatly reduced, which is beneficial to manpower, Material saving.

The cylindrical member in the device structure of this case exists, and can guide the liquid flow inside the container to rise rapidly along the internal channel of the cylindrical member, and after the microwave excitation assists and the photocatalytic oxidation synergistic reaction area, by The top area diffuses around, sinks through the peripheral area, reaches the bottom area of the inner cavity of the container, and then converges to the internal passage of the cylindrical member through the bell mouth of the cylindrical member to continue its cycle; of course, the bunched rising The dragging force of the bubble flow is the main driving force of this cycle; this guided relatively large-scale liquid circulation movement helps to ensure the homogenization of the liquid degradation reaction process inside the reactor, which is very important for such a large-scale degradation reaction in this case. device, it is necessary.

The ultraviolet radiation source of the reactor in this case is a microwave-excited electrodeless ultraviolet lamp. The ultraviolet radiation of this lamp is characterized by high power and high intensity. However, the effective penetration depth of ultraviolet rays in liquid water is only about 20 cm, so The area within about 20 centimeters around the quartz tube is the effective area, which is the efficient area of the photochemical catalytic oxidation degradation reaction; the device in this case uses the cylindrical member to gather the air bubbles from many microporous aeration heads Flow, so that it is released concentratedly towards the effective area of photochemical catalytic oxidation around the quartz tube. This method helps to increase the oxygen atmosphere supply intensity in the effective area around the quartz tube, and helps to accelerate the process of ultraviolet photocatalytic oxidation degradation reaction.

Based on the structure of this case, the capacity or processing capacity of the reactor can be greatly expanded. The large expansion is realized by greatly expanding the design volume of the microwave zero-irradiation area or the microwave weak-irradiation area. Then, from the appearance, the reaction The horizontal and vertical dimensions of the reactor can of course be greatly expanded. Therefore, the depth of the liquid inside the reactor can also be greatly deepened, for example, it can be deepened to one meter, two meters, three meters, four meters, five meters, Six meters, even ten meters, etc., in the case of deep enough depth of liquid, the rise path of ozone-containing air bubbles is long enough, and the contact time of ozone-containing air bubbles with water body is long enough, and it can interact with enough water during its rise. The reductive substance encounters, and completely or almost completely depletes the ozone contained in the bubbles, thus, the problem of incomplete utilization of the oxidation potential of the ozone component in the ozone-containing air bubbles can be completely solved, and, due to the long rise The path leads to ozone depletion, and the reactor tail gas will no longer contain ozone that will cause environmental pollution.

In this case, an external multi-stage filter is used to achieve step-by-step interception of catalyst particles from large aggregate particles to small-scale collision fragments of tens of nanometers, to recover and reuse photocatalysts almost completely, and to prevent catalysts almost completely. Secondary pollution caused by loss; the step-by-step interception structure can protect the secondary filter from hard blocking of large particulate matter; the first-stage pre-filter pore size is between 5 microns and 300 microns The pore size of the second-stage microfiltration is between 25 nanometers and 1000 nanometers, and the pore size of the third-stage ultrafiltration is between 15 nanometers and 2 nanometers; such an interception structure can fully intercept nano-scale photocatalysts, Of course, it can almost completely intercept gas-phase titanium dioxide P25, a catalyst with an average particle size of 21 nanometers; as mentioned above, nano-scale gas-phase titanium dioxide catalysts such as P25 are commercially available catalysts that can be purchased in large quantities, and are also durable. , stability, and photocatalytic performance in the ultraviolet band are known to be good photocatalysts. Of course, it is also a photocatalyst that is actually preferred in industrial applications; the interception structure of the catalyst in this case matches the actual capacity and actual variety of the catalyst market supply. , Fusion.

Moreover, the catalyst intercepting mechanism in this case is external, and its filter element does not need to be immersed in the strong oxidation and strong ultraviolet radiation liquid inside the reactor. Therefore, it is completely unnecessary to consider the tolerance to ultraviolet radiation and strong oxidation conditions. In this way, There is no special tolerance limit on the selection of filter element material, and you can choose from a wider range of optional materials, without being limited to more expensive PVDF and other materials.

All levels of filters involved are commercially available, and the sewage outlets of commercially available filters at all levels are the outlets for discharging sewage during backwashing. This type of backwashing equipment is used in this case to intercept catalyst particles step by step. The sewage outlet of the original commercially available equipment was repurposed in this case as the recovery and reuse outlet or the return and reuse outlet of the trapped catalyst particles.

As mentioned above, based on the structure of this case, the capacity or processing capacity of the reactor can be greatly expanded. The large expansion is achieved by greatly expanding the design volume of the microwave zero-irradiation area or the microwave weak-irradiation area. Then, From the appearance, the horizontal and vertical dimensions of the reactor can of course be greatly expanded. Therefore, the depth of the liquid inside the reactor can also be greatly deepened, for example, it can be deepened to one meter, two meters, three meters, Four meters, five meters, six meters, or even ten meters, etc., when the depth of the liquid is deep enough, the rising path of the ozone-containing air bubbles is long enough, and the contact time of the ozone-containing air bubbles with the water body is long enough, and the rising process It can meet with enough reducing substances and completely or nearly completely deplete the ozone contained in the bubbles, thus, the problem of incomplete utilization of the oxidation potential of ozone components in the ozone-containing air bubbles can be completely solved, and , due to the depletion of ozone due to the long rising path, the reactor tail gas will no longer contain ozone that will cause environmental pollution; only when the reducing substances in the treated water, that is, organic pollutants are completely degraded, the water body There are no organic pollutants available for the ozone oxidation reaction in the water, so that the excess ozone may no longer be consumed and escape the liquid surface through a long rising path; as mentioned above, one of the several problems solved in this case at the same time One of them is to strengthen the relatively large-scale circulation of the liquid inside the reactor. This enhanced large-scale circulation mechanism promotes the uniformity of the degradation reaction process of the organic pollutants contained in the liquid inside the reactor. Therefore, in this case, the structure Under the allowable processing capacity framework of several cubic to tens of cubic or even hundreds of cubic volumes, when ozone escapes above the liquid level inside the reactor, it means that the degradation reaction inside the reactor has reached the end, and The internal liquid reaches the end of the degradation reaction evenly and uniformly as a whole. This end point determination factor matches the conditions provided by the structural scheme of this case; an ozone sensor is installed at the tail gas discharge port of the reactor in this case. The detection of ozone means that the degradation reaction inside the reactor has reached the end, and the ozone sensor is connected with the ozone warning device or the ozone content display or the composite mechanism of the ozone warning device and the ozone content display to provide accurate instructions to the operator. In this case, the electric signal output by the ozone sensor is transmitted to the power controller through the cable, and the power controller is connected with the magnetron and the air pump respectively through the cable, and the power controller performs the power switch according to the electric signal it receives. Action, of course, its mode of operation is, when the power controller receives the signal of the ozone escaping sent by the ozone sensor, it will automatically shut down the power supply to the magnetron and the air pump; The end point of the degradation reaction process inside the reactor; and according to this structural scheme, when the reaction reaches the end point, the power supply of the magnetron and the air pump is automatically turned off, and the energy injection into the reactor is stopped in time, so that unnecessary energy waste can be avoided; and According to the structure of this case, when the degradation reaction reaches the end point, the power supply of the magnetron and the air pump can be turned off in time. The source closing action is also synchronous, and the ozone generation process is terminated at the same moment. Since the ozone generation process is terminated in time, there will be no more than necessary ozone released from the exhaust outlet, thereby avoiding unnecessary secondary pollution Or secondary pollution; the structure of this case determines that it has no surplus ozone for emission.

In the structure of this case, the microwave irradiation airspace inside the reactor is forcibly cut off and restricted. In this case, an external cascaded multi-stage backwash filter structure is used to finely intercept catalyst particles. The backwash hollow fiber microfiltration Both the membrane module and the backwash hollow fiber ultrafiltration membrane module are placed outside and away from the core of the reactor, and the microwave cannot irradiate the membrane module at all. Based on the structure of this case, the point-like hole-through thermal penetration is completely bypassed. Destroy the problem, which is thus well resolved.

The bottom surface of the inner chamber of the reactor in this case is gradually depressed from the periphery to the central area, and the slope of the depression is between 5 degrees and 35 degrees. The ultrasonic transducer in this case is attached to the bottom surface of the reactor inner chamber. The position of the outer side or the inner side of the bottom wall of the reactor corresponding to the deepest part of the depression; as mentioned above, the structure of this case is also conducive to promoting the relatively large-scale circulation of the liquid inside the reactor. The way the liquid circulates is The surrounding liquid sinks, the middle liquid rises, and so on. As mentioned above, in some cases where the pH value is not pre-adjusted in place or the pH value is inappropriate, titanium dioxide particles are prone to agglomeration, which will affect its effective work. The interface area affects its photocatalytic efficiency; especially for those relatively small particle size segments in this particle size range, it is more prone to agglomeration problems caused by improper pH value pre-adjustment and inappropriate pH value; For the agglomeration of catalyst particles, it is necessary to take effective measures immediately to depolymerize the agglomerates; in the case of severe agglomeration of catalyst particles, some of the relatively heavy large agglomerates tend to Settling gradually towards the bottom of the reactor cavity, in the structure of this case, the bottom of the reactor cavity is a depression structure, and the structure of this case can push the liquid inside the reactor to make the relatively large-scale circulation movement, the effect of this large circulation movement Together with the ubiquitous natural gravity, it will push and sweep the settled large aggregates along the slope of the depression structure to the deepest part of the depression and make them gather there. The ultrasonic transducer in the structure of this case is exactly The structural position located at the deepest part of the depression, the deepest region of the depression is not only the region where the large aggregates finally gather, but also the place where ultrasonic waves can attenuate the least, the shortest distance, the most intensely, and most effectively target the large Agglomerates deagglomeration operation area; the structure in this case can allow the minimum ultrasonic energy loss to achieve the maximum ultrasonic deaggregation effect; this case can gather aggregate sediments, and the aggregate sediments are most concentrated area, to carry out depolymerization operation; of course, the ultrasonic waves originating from the bottom of the reactor can also radiate to other areas in the liquid inside the reactor, and play a role in depolymerization for those relatively small aggregates that are still in suspension; the relevant ultrasonic waves in this case The radiation mechanism is a mechanism that can be activated or deactivated according to the needs; this case thus realizes the immediate in-situ disposal of the problem of the agglomeration of the catalyst particles.

The outer wall of the quartz tube used to shield the electrodeless ultraviolet lamp in the structure refers to the outer wall of the quartz tube. After a long period of contact with the industrial wastewater to be treated, it is inevitable to gradually accumulate scale. Inorganic impurities touched by the photocatalytic reaction, due to the fouling phenomenon formed by this mechanism, are easy to be observed after the equipment has been running for a long time; the fouling layer attached to the outer wall of the quartz tube is only a thin layer , is also enough to significantly block the ultraviolet radiation of the electrodeless ultraviolet lamp, which will lead to a substantial reduction in the actual treatment efficiency of the microwave photocatalytic reaction treatment device; During the deaggregation operation for the occasional severe agglomeration of catalyst particles, the radiated ultrasonic waves will of course reach the structural position of the quartz tube. Focus on the ultrasonic cleaning and descaling work for the fouling on the surface of the quartz tube; and the installation position of the ultrasonic transducer is far away from the structural position of the quartz tube, and the ultrasonic radiation has been attenuated when it reaches the position of the quartz tube. Therefore, the surface of the quartz tube The ultrasonic impact received is a low-intensity ultrasonic impact, which can not only gently remove scale, but also avoid or greatly weaken the loss of surface finish of the quartz tube that may be caused by ultrasonic cavitation; based on the structure of this case, The fouling layer on the outer wall of the quartz tube can be removed immediately and effectively without dismantling the machine, thereby maintaining the continuous high efficiency of the microwave photocatalytic degradation reactor.

The pH value of the water body inside the wastewater degradation reactor is a key factor affecting the dispersion stability of the catalyst; the pH probe installed in the structure of this case and its associated pH value display instrument and associated alarm can be used when the pH value exceeds the catalyst. In the case of dispersed stability range, an alarm is issued actively. Based on the structure of this case, relevant operators can immediately perceive the tendency of catalyst reunion inside the reactor and make immediate disposal. The microporous stainless steel sleeve and its installation method in the structure of this case are indispensable important components matched with the principle of this case and the structure of this case.

The membrane module in the structure of this case is always in the working condition of being completely submerged, and the membrane module has no chance to contact the air, and keeps wet and completely submerged. Therefore, there will be no such easy In the case that the membrane module is often exposed to the air, the working condition of the membrane module in the structure of this case is more in line with the inherent use conditions of the membrane module itself, which is more conducive to maintaining the normal performance of the membrane module and ensuring the safety of the membrane module. Normal service life.

In the structure of this case, a catalyst thick slurry transition tank is set up to temporarily store the liquid with a relatively high concentration of catalyst from the backwashing process of each backwash filter, so as to avoid directly pouring back the liquid with a relatively high concentration of catalyst The reactor, in this way, avoids the problem that the concentration of the catalyst in the liquid inside the reactor gradually increases with the extraction process of purified water, which can reduce the burden on the subsequent extraction of purified water. With such a catalyst thick slurry transition tank structure , after the clean water extraction process is completed, the catalyst thick slurry can be poured back into the reactor; in addition, the water pump used to transport the waste water to be treated, the water pump outlet leads to the inner cavity of the catalyst thick slurry transition tank, Then, the waste water transported to the final destination reactor must first flow through the structural section where the catalyst thick slurry transition tank is located. This structure can use the injected wastewater to wash the catalyst thick slurry transition tank and deposit it All the catalysts are brought back into the reactor; the ultrasonic transducer installed at the bottom of the catalyst thick slurry transition tank can break the cluster and depolymerize the catalyst that is agglomerated and deposited due to high concentration, and contact its deposition state, which is convenient The injected wastewater will completely bring these catalysts back to the inner cavity of the reactor; the water level float switch located on the top of the catalyst thick slurry transition tank is convenient for balancing the internal and external air pressure, and helps to prevent the injected wastewater from overflowing the catalyst thick slurry. slurry transition tank.

In the structure of this case, a pair of reed float level controllers connected through a relay to the power supply cable of the water pump for conveying waste water can automatically avoid excessive filling of waste water into the inner cavity of the reactor. This prevents the waste water from overflowing the reactor; another pair of reed float level controllers connected to the power supply cable of the booster pump through another relay can prevent the liquid inside the reactor from being over-extracted Cause the booster pump to run idly and run dry, so that the booster pump motor can be avoided from burning out.

Any valve body on all fluid passages in the structure of this case can choose to use solenoid valves, and these cables can be arranged on a panel. This structure allows remote centralized control of the valve body switch action corresponding to each program.

In short, under the premise of taking into account the synergistic and coupling effects of the microwave excitation assistance and photochemical catalytic oxidation, the project achieved the goal of greatly expanding the designed capacity of the reactor; Scale circular movement; its structure solves the problem of incomplete utilization of ozone oxidation potential; its structure also achieves a wide range of fine interception of nano-scale catalyst particles from large particles of aggregates to collision fragments of tens of nanometers; The choice of the material of the filter core is also enlarged due to this structure; the information of the end point of the degradation reaction can be known in time; the energy injection to the reactor can be automatically closed when the end point of the degradation reaction is reached; The generation process of ozone is terminated in time to avoid unnecessary secondary pollution; its structure can immediately deal with the occasional severe agglomeration of catalyst particles in situ, and at the same time, it can also take the low-intensity mild ozone that has been moderately weakened by remote transmission. Ultrasonic cleaning of the surface of the quartz tube maintains its excellent ultraviolet light permeability; its structure can also actively detect the tendency of catalyst agglomeration, and an alarm will be issued when the relevant parameters exceed the standard; its structure is also conducive to the complete immersion of the membrane module Its structure can realize the proper transitional storage of catalyst thick slurry through the catalyst thick slurry transition tank structure, which overcomes the problem of excessive difference before and after the membrane separation load; its structure can also realize the automatic control of the wastewater filling water level; its structure And when the clean water is extracted to the limited water level, the power supply of the booster pump can be automatically and timely turned off, which is beneficial to the protection of the booster pump motor.

The structure of this case solves one of the problems mentioned in one package, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, and fourteen.
