The present invention relates to a high-efficiency circulation control redox tank for wastewater treatment facilities and a wastewater treatment method using the same.

In recent years, due to the rapid development of industrialization and urbanization, the natural environment and the living environment are deteriorating to the point where they can no longer be left unattended.In particular, the seriousness of water pollution is increasing day by day. .

In addition, water pollution of rivers and lakes is the most severe, and the main cause of water pollution is the inflow of wastewater such as livestock manure at high concentrations.

Therefore, although proper wastewater treatment of these pollutants is required, there are still many difficulties in managing the specificity of the wastewater and management of changes in water quality regarding the actual operation status and verification of various wastewater treatment technologies currently introduced at home and abroad. I'm talking about it.

In the future, treatment facilities such as livestock wastewater, organic industrial wastewater, and wastewater that cause eutrophication in surrounding waters as the main cause of environmental pollution, such as the regulation of ocean dumping, may be applied to joint treatment plants or individual purification facilities according to the scale of small-scale farming corporations and industries at the village level. Treatment will be expanded.

However, among the many wastewater treatment facilities required, most of them are not functioning due to the inadequate design and management methods in the case of livestock wastewater joint treatment plants. Due to lack of understanding of wastewater concentration and lack of management ability, it is not functioning properly.

In addition, it is difficult to secure industrial competitiveness because the cost invested to treat livestock waste, organic industrial wastewater, and wastewater is excessive compared to the related wastewater treatment industry size. It is hard to find a place where the stability of water quality is verified by the discharge system.

For example, in the prior art, there are techniques developed in Korean Patent Nos. 151928, 100603, 229406, 271942, 33531, Japanese Patent No. 3122654, and the like.

In the conventional technology as described above, various methods of livestock wastewater are applied, but many methods are operated only when an expensive microorganism or an expensive water treatment substrate such as membrane separation is used, and the cost of maintenance or replacement in the future This is very expensive, and there is a serious problem in maintenance.

In addition, the conventional technology has a lot of uneconomical problems due to artificial, largely expensive facilities, rather than the effective approach of the natural treatment method, it will take a long time to recover the water quality of the facility because the biostable at the replacement time is poor.

Moreover, domestic livestock wastewater or manure is recognized as a major cause of aquatic eutrophication, but existing organic treatment centers cannot solve environmental pollution problems such as N / P eutrophication.

In order to improve livestock wastewater treatment efficiency by improving existing facilities, conventionally, microbial activators or technologies such as bio-reactors have been introduced and operated, but additional costs of microbial agents are generated and replaced. Due to the unfavorable operation and installation costs of related treatment facilities, such as the temporary suspension of facility operation at a time and the reactivation rate of injected seed due to instability of microbial solidification technology, it has many problems in practical application. have.

In addition, conventionally, it is difficult to maintain a proper temperature during treatment efficiency, automated operation, and microbial activity of a wastewater treatment facility, and there is a disadvantage in that the bioreactor foam removal and liquid liquefaction are very insufficient.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to change the load of the inlet flow rate and concentration when the inflow of waste water, the operation of the facility increases and decreases the air supply and circulation rate Maximizes the contact rate of aerobic / arbitrary / anaerobic microbial metabolism through spawn media contact, and directly cools denitrification heat and organic oxidation heat generated during biological metabolism process with aeration microbial mixture to maintain microbial growth temperature and changes in water quality conditions. It eliminates problems such as microbial troubles and foaming, and functions automatic control operation of facilities by water quality measuring equipment (DO, PH, flow meter, ORP, temperature) to minimize the treatment scale of the facility and reduce the processing cost and operation. It is possible to obtain stable treated water quality even with general water quality management experience, and to use it as a liquid fertilizer. High-efficiency circulation-controlled redox for wastewater treatment that can improve the functional liquefaction without cost and other auxiliary facilities such as the function of reducing the temperature, deodorizing function, high-speed nitrification function, and defoaming function caused by foaming in response to the increase of temperature The present invention provides a wastewater treatment method.

In order to achieve the above object, the present invention is a high-efficiency circulation control redox for the waste water treatment consisting of pre-treatment to process the waste water from which the residue is removed, the upper part of the cooling tower body in which the pre-treated waste water flows from the outside upper side In addition to the fan is installed, an eliminator is installed on the lower side of the cooling tower body, the top of the inside of the cooling tower body is formed in a multi-tiered microbial carrier in the form of a checkered contact media material layer for growing the biofilm on the surface is installed It comes into contact with the waste water falling from the top to the bottom, and the white fungi and various fungi and the introduced microorganisms that function when the wood corrodes on the bottom of the spawn contact media layer inside the cooling tower body. The wood media layer is arranged to metabolize and grow biofilm, Bentonite layer for controlling bulking by controlling identification of filamentous fungi is disposed in the lower part of the wood media layer inside the cooling tower body, and an oxidizing tank having an diffuser which discharges air by a blower is installed in the lower part of the cooling tower body. And the air is brought into contact with the wastewater which has passed through the spawn contact medium layer and the bentonite layer, and the wastewater which has flowed through the flow port formed on the side of the oxidizing tank is discharged through the biofilm filter through the first and second reduction tanks. High efficiency circulation for sewage / wastewater treatment, which is moved to a tank (treatment tank) or a liquid storage tank, and the wastewater in the first and second reduction tanks is transported and dropped to the upper portion of the spawn contact media layer by a circulation pump. Provide a controlled redox aid.

The present invention thus made is a highly efficient cyclically controlled redox tank applying the basic principle of oxidation and reduction, which is the basic metabolic process of activated sludge microorganisms to wastewater treatment, firstly applying and recycling spawn contact media in the wastewater treatment of organic wastewater / wastewater treatment facilities. By improving the treatment efficiency by constructing various functional tanks such as control method and oxidation tank and reducing tank, it is possible to escape from the water purification system, which is stable to load fluctuations, and the cooling method such as the freezer, which was a high-cost and low-efficiency facility in wastewater treatment plants with high water temperature. The direct cooling function to reduce the temperature of the microbial wastewater in the reactor by the direct cooling method to lower the appropriate microbial aeration tank temperature to the atmospheric temperature, and the third, pre-treated livestock manure can be used as a liquid fertilizer production facility.

After the process of pre-treatment physical screening of various raw wastewater from organic sewage, organic wastewater and industrial production, and passing through the active sludge spawn contact media layer of circulating controlled recirculation aid, the seed is eluted to give useful seed for wastewater treatment. In the biofilm formed on the surface of the media, adsorbing and metabolizing the microorganism through random, aerobic and anaerobic strains, increasing the amount of microorganisms in the redox tank, increasing the water quality and improving the efficiency of microbial metabolism in wastewater treatment facilities. Bioreactor temperature control function by direct cooling control of the circulating microorganisms in the reaction tank and dissolution in wastewater using the principle of reducing the solubility due to temperature decrease when evaporating water vapor as it falls into multiple stages while dropping the spawn contact media layer. Process of volatilization of volatile and odorous substances Therefore, when there is an associated deodorizer, the deodorizer is connected to the deodorizer by the upper fan or blower to remove the odor, and the wastewater particles that fall through the media layer fall into the oxidizing tank and oxidize through self-defoaming effect. It removes bubbles formed in the upper part of the tank, so it is possible to complete the defoaming and water treatment without the existing scum removal pump, the defoaming pump and the antifoaming facility. The air supply is connected to the DO (dissolved oxygen) measuring instrument. By increasing and decreasing the flow rate, the water treatment functionality is increased according to the inflow load, and the circulation volume of the circulation pump is increased or decreased according to the inflow amount (Q, flow meter) and DO, and the operation is controlled by the appropriate microbial metabolic efficiency to change the inflow load condition. It can be processed by maintaining optimum temperature and metabolic conditions. A specific capacity is capable of maintaining a stable wastewater treatment facilities.

In addition to obtaining excellent removal efficiency of organic matter through the median contact media layer and the sensitizer of oxidizing tank, it is possible to treat nitrogen phosphorus, which is the main factor of eutrophication, with high efficiency at the same time through the two-stage reduction tank. The film and spawn contact media achieve the activity of microorganisms, and filamentous bulking control by algae breeding is easy.

Especially in the case of small wastewater treatment plants with a lot of inflow load fluctuations, the process is simple and efficient, so if the inflow load is minimal, only the circulation pump is treated. Flow meter, ORP, temperature) can be controlled by the equipment so that anyone can easily obtain stable water quality through the operation of the wastewater treatment system.

In addition, the supernatant, that is, the treated water separated from the reduction tank through the biofilm filtration tank is once again filtered by the biofilm filter, so that SS of the effluent can be removed to obtain treated water of high quality wastewater.

In addition, the pretreated manure of livestock manure can be introduced into the facility, nitrified through a strong air supply in the oxidizing tank to settle the microorganisms in the reducing tank, and can also be used as a liquid fertilization production facility that resources the supernatant of the treated water into the liquid fertilizer.

At this time, the problem caused by the exothermic reaction and the large amount of foaming problems and odors in the prior art has been difficult to install the existing liquefaction facilities many complementary facilities, excessive installation cost and maintenance, but the present invention is in the air By the cooling by increasing and decreasing the appropriate temperature required for microbial activity, giving useful water treatment spawn as a spawn contact media layer, through the formed biofilm to increase the activity through microbial metabolism to anaerobic microorganisms of aerobic, By removing the foam through the deodorizing facility by transferring the odor to the deodorization to obtain a high-efficiency liquid costs at a low cost and to deal with additional environmental pollution problems at a low cost.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 to 3 are diagrams illustrating a high efficiency circulation control redox tank for wastewater treatment according to the present invention, wherein the redox tank is pretreated to treat wastewater from which residues are removed.

A fan 2 is installed at an upper portion of the cooling tower body 1 into which the pretreated wastewater is introduced from an external upper side, and an eliminator 3 is installed at a lower side of the cooling tower body to adjust the inflow amount of air.

The inside of the cooling tower body (1) is formed in a multi-tiered microbial carrier in the form of a checkerboard, the seed contact medium layer (4) is installed on the surface to grow the biofilm is in contact with the wastewater falling from the top to the bottom.

Here, as an example, the biofilm is assimilated and grown with waste water, and the microbial carrier is a spawn contact medium, which is a bacterium contact bacterium, a sidelobe extract, rice bran, mineral, activated carbon, clay, bentonite, and trace metal algae. It is made by mixing to activate microorganisms.

Bentonite layer 5 for controlling bulking by controlling identification of filamentous fungi is disposed under the spawn contact medium layer 4 inside the cooling tower body 1.

In the lower part of the cooling tower body 1, an oxidizing tank 8 having an diffuser 7 for discharging air by the blower 6 is installed, and the seed contact medium media layer 4 and the wood media layer 4a are provided. ), Air is brought into contact with the wastewater passing through the bentonite layer 5 in sequence.

Then, the wastewater, which has flowed into the source port 8a formed on the side of the oxidizing tank 8, passes through the biofilm filter 11 through the first reduction tank 9 and the second reduction tank 10, It is moved to the same discharge tank 12 or the liquid storage tank 13 as shown in Figure 2, the waste water in the first reduction tank (9) and the second reduction tank 10 by the circulating pump 14, the seed contact contact It is transferred to the upper portion of the media medium layer 4 to be diffused and dropped.

In addition, the present invention by installing the first control valve (15) at the outlet of the first reduction tank (9) and the second control valve (16) at the outlet of the second reduction tank (10) to the circulation The amount of circulating waste water in the first reduction tank 9 and the second reduction tank 10 circulated by the pump 14 is adjusted.

In addition, as shown in FIG. 3, the amount of waste water flowing into the cooling tower body 1 from the outside is measured, and the dissolved oxygen in the oxidizing tank 8 is measured to provide an diffuser in the oxidizing tank 8. The blower 6 and the circulation pump 14 which are connected to 7 are controlled by the controller 17.

In addition, the present invention includes a deodorizer 18 for removing the odor by sucking the air flowing out to the outlet side of the fan (2) installed on the upper portion of the cooling tower body (1).

The highly efficient circulation control redox tank for wastewater treatment thus treated treats wastewater as follows.

A diffuser port (7) connected to the blower (6) discharges air in the oxidizing tank (8) to contact wastewater in the oxidizing tank (8) with air, and is formed on a side surface of the oxidizing tank (8). 8a) is introduced into the first reduction tank (9) and the second reduction tank (10) step by step, the waste water in the first reduction tank (9) and the second reduction tank (10) circulating pump ( 14) is transported to the top of the spawn contact media layer 4 in the cooling tower body 1 to be dispersed and dropped, and the waste water dropped by the circulation pump 14 passes through the spawn contact media layer 4. While being cooled in contact with the air introduced into the eliminator (3) of the lower side of the cooling tower (1).

In addition, as the microbial carrier is in checkered grid-like lattice shape, the spawn contact medium medicament layer 4 is in contact with the inflow water falling from the top to the bottom, and the carrier microorganism is eluted to give the spawn to improve microbial activity.

The spawn contact media layer 4 is arranged in a square lattice shape to grow a biofilm on its surface, and the microorganism of the aerobic anaerobic random substrate removes organic matter and nutrients through metabolic process, and the spawn contact media layer ( 4) Put a wood media layer (4a) in the lower portion of the white rot fungi and various fungi (fungi) and the introduced circulating water microorganisms to metabolize the surface to form a biofilm, the bottom of the wood media layer (4a) By placing the bentonite layer 5, the identification of filamentous fungi is controlled to control the bulking.

The wood medicament layer 4a is a wood 5 cm long by 1 cm long wood carving stacked inside a stainless steel mesh (not shown) inside the surface of the wood or the wood odor fungi functioning when the fiber in the wood corrodes various Circulating water microorganisms introduced into fungi and the like metabolize the surface to form biofilm.

Therefore, the wood media layer (4a) is a latent heat that evaporates while falling from the top to the bottom as it functions as a microbial metabolic function through the degradation of hardly decomposable substances such as lignin and the final aerobic strain of fiber The temperature reduction process and the cooling of the incoming water through the incoming cooling air and the volatiles and odor causing substances dissolved in the oxidizing tank (8), saturated aromatic substances, etc. The volatilization is carried out together with the reduction, so that the water is circulated continuously.

On the other hand, the operation rate and the circulation rate of the blower 6 connected to the oxidizing tank 8 by the dissolved oxygen (DO) concentration of the oxidizing tank 8 based on the amount of external wastewater flowing into the cooling tower body 1. The operation rate of the pump 14 is increased or decreased by the controller 17.

When the waste water falls while contacting the spawn contact medium layer 4, which is installed in multiple stages, the specific heat is large. Therefore, latent heat is scattered with water vapor during the dropping to evaporate the organic oxidation heat and the denitrification heat, and the temperature of the microorganism activity of the oxidizing tank is changed to the atmospheric temperature. Will be lowered.

By controlling the inlet cooling air by opening and closing the eliminator (3) provided in the cooling tower body (1) to control the temperature in winter, waste water by placing a line (14a) on the outlet side of the circulation pump (14) By controlling the circulation rate of the vesicle function and temperature control.

As the waste water circulates and falls, scum and bubbles formed in the upper part of the oxidizing tank 8 are continuously removed, and the scum is dissolved into the oxidizing tank 8 through the defoaming to increase the microbial metabolic rate.

The circulation pump 14 is used to increase or decrease the circulation rate relative to the total inflow, thereby treating wastewater, thereby reducing facility installation capacity and auxiliary facilities.

In other words, in the present invention, the raw water is introduced through the pre-treatment physical screening process, mixed with the circulating water, and passed through the spawn contact medium layer 4.

At this time, the microbial biofilm is formed on the surface of the spawn contact medium layer 4, and the spawns in the media are eluted to cause a decomposition mechanism of the influent.

The wastewater forms microbial metabolism through random / aerobic / anaerobic strains in contact with the microorganisms, and the water particles are finely chopped while continuously falling from the top to the bottom while contacting the multi-media media. As the volatiles and odorous substances remaining in the influent break through the volatilization process, they emit latent heat of the water vapor in the circulating water and the water temperature is lowered.

Of course, by controlling the operating time of the fan (2) or by controlling the opening and closing degree of the eliminator (3) to control the desired water temperature.

Anyway, the wastewater falling down is widely distributed in the upper part of the oxidizing tank 8, and drops to remove the bubbles formed in the upper part of the oxidizing tank 8, thereby exhibiting a defoaming effect. Promote

In other words, the waste water is circulated and dropped widely through a baffle plate composed of a bentonite layer and a wood media layer to continuously remove scum and bubbles formed in the oxidizing tank (aeration tank / bioreaction tank), and then scum through the parcel. It dissolves in this oxidation tank to increase the microbial metabolism rate.

The air discharged from the diffuser (7) by the blower (6) below the oxidizing tank (8) increases or decreases the dissolved oxygen in preparation for the inflow load to the microorganisms in the waste water in the oxidizing tank (8), and the sufficient amount of air Supply to cope with load fluctuations.

The waste water which has passed to the first and second reduction tanks 9 and 10 is sedimentable in the first reduction tank 9 and the aeration tank mixture (MLSS) is sedimented and collected, and anoxic concept reduction treatment is performed, and the second reduction is carried out. In the tank 10, the anoxic reduction treatment residence time is increased to further increase the solid-liquid separation ability of the supernatant, and the effluent can be filtered and discharged through the biofilm filter 11.

At this time, the circulation pump 14 controls the first and second control valves 15 and 16 provided at the lower portions of the first and second reduction tanks 9 and 10, respectively. Increasing the conveying amount and concentrating the concentration of the settling microorganism, and also control the conveying amount of the second reduction tank 10 to reduce the amount of microorganisms and to control and discharge the suspended solids (SS) of the supernatant.

In operation, the circulation pump 14 is connected to the inflow flow meter and the measuring device 19 such as DO (dissolved oxygen) of the oxidizing tank 8 to increase or decrease the air supply amount, and the circulation amount by the circulation pump 14 is adjusted to the hydraulic amount. (Q, flow meter) and DO (dissolved oxygen) can be automatically controlled to the inflow load fluctuations by interlocking to adjust.

The biggest difficulty caused by load fluctuation due to the nature of wastewater treatment is the microbial problems (bubbles generation / sedimentation deterioration bulking problem / discharge water deterioration and other problems). In the present invention, the contact circulation rate and aeration intensity are increased depending on the wastewater inflow and water quality. With the increase and decrease of the existing facilities, the optimal DO, temperature maintenance and MLSS amount are maintained in preparation for the inflow with existing facilities, and the anti-foaming function, temperature control function, spawning function, and redox treatment function are performed in parallel. It is possible to maintain stable wastewater treatment facilities / cooling facilities / liquid manufacturing facilities.

In addition, the present invention can process nitrogen and phosphorus, which are the major factors of eutrophication as well as organic materials, at the same time with high efficiency, and the process is also simple and efficient, and controlled by automation (DO, PH, flowmeter, ORP, temperature) equipment. As it is controlled, anyone can drive easily, and stable water quality can be obtained.
