Description

Detailed Description of the Invention

This invention is a hypochlorite solution prepared by blowing electrolytic chlorine-producing gas into an oxidizing and acidic solution of an anode chamber liquid and a reducing alkaline solution and an alkaline electrolyte solution of a cathode chamber made by diaphragm electrolysis as an alkaline oxide solution, Separately treat this into odorous cleaning water for deodorizing offensive odor gas from sewage, fecal sludge, domestic wastewater, and industrial wastewater to deodorize, and then add both liquids in both electrode chambers separately to the odorous pollutants and oxidize them. And neutralize the malodorous acidic liquid with alkaline electrolyte, treat it as neutral and deodorize it, and distinguish between scum cake like sewage and sewage and urine water as an electrolyte directly with ultraviolet irradiation. , Salt, Glauber's salt,
By electrolytically dialysis the wastewater filtrate with addition of an electrolyte such as an aromatic alkali, the scum cake after deodorization and deodorization is subjected to dry fermentation by the fermentation method and reused as an organic fertilizer and fermenting inoculum to ferment the wastewater. Utilizing electrolytic dialysis and fermentation method, which is characterized by preventing heat from evaporating into the river.
It is related to sludge treatment of moving toilets such as trains, airplanes, automobiles and buses, and deodorizing decomposition fermentation treatment of parks, highways, racetracks, bicycle racetracks, boat racetracks, baseball fields, and domestic toilets. As a general wastewater treatment method, an activated sludge method is known, but a large amount of water is used. For example, in the treatment of domestic wastewater such as human excrement and urine water, it is diluted with 40 times as much water as solids and then watered. , A bad odor that is generated during a waterfall during the period of time during which the aerobic or anaerobic bacteria are acted on has been a pollution. Because of this. Since the deodorizing treatment with the cover of the closed lid and the activated carbon has been performed, the treatment cost is high. In addition, the bad odor in the tank was a pollution because the concentrated concentrated waste water that had been vaporized was once stored in the tank. Then, the concentrated liquid is further coagulated with a coagulant and centrifuged to separate the scum cake and the offensive malodorous water, but this scum cake also has a strong malodor and the filtered offal liquid is placed in a water tank. Since it is recycled, the bad odor of this strong odorous filtrate cannot improve the pollution of water treatment. Therefore, this method is a diaphragm electrolysis method,
That is, the oxidative property of the anolyte prepared by electrolyzing the positive and negative bipolar chambers with the diaphragm by electrodialysis, and
Hcl, Hcl, H2So4, lactic acid or other organic acid-containing acid solution and alkaline solution produced by electrolysis in the cathode chamber are made, and a caustic alkaline electrolysis dialyzer is made separately to make oxygen gas in the anode chamber and cathode. Uses the alkaline liquid and hydrogen gas generated in the chamber to deodorize and purify scum cake and sewage.
Separately, a sodium sulfate solution was made by using an electrolytic dialyzer using sodium sulfate as an iron pole or a copper pole, and an alkaline solution was made as a cathode, and both solutions were distinguished from each other for deodorization decomposition. Oxidation, reduction and neutralization are carried out by alternately using the electrolytic solution so that the metal ions enhance the cohesiveness and the deodorizing property, or the waste water solution is directly treated as an electrolytic solution while being irradiated with ultraviolet rays. Deodorized products and high-pressure oxygen are produced by isolation electrolysis, and this is used for deodorizing decomposition of scum cake to prevent foul odor pollution and treats scum cake with organic fertilizer, deodorant fiber etc. Since it is a method that has improved the method, it is effective in preventing secondary pollution when used for the treatment of moving vehicles, bicycle racetracks and other public toilets, and has the effect of improving pollution of rivers. In addition, when salt mirabilite water is used as an electrolytic solution in this electrolytic dialysis, an oxidizing and acidic solution is formed in the anode chamber. Particularly, in the case of salt, chlorine gas is generated. First, the offensive odor gas generated from the sewage liquid is washed and then deodorized by washing with a reducing alkaline liquid.
This amphoteric water is neutralized in the mixing chamber, filtered by a first-class filter, electrolyzed by another diaphragm electrolyzer to neutralize deodorization, and then filtered and recycled to the original electrolytic solution. In addition, when using the iron electrode as the anode of this diaphragm electrolysis in the gas treatment in the activation method, a sulfuric acid soda solution was added to distinguish it from the cathode, and the cathode was platinum-plated on the titanium surface or aluminum alloy. After the iron sulphate solution obtained from the anode was electrolyzed using a silicon electrode,
The concentrated stock solution from which the supernatant was removed was transferred to a concentration tank by a pump and added to the one that was added to oxidize it to agglomerate the scum cake and neutralize it with an alkaline electrolyte. The product is mixed with bark fermented fiber and fermented, the scum cake is hydrolyzed, and then it is commercialized as an organic fertilizer, half of which is recycled as inoculum and re-fermentation material. Also, since the scum concentrated liquid in the concentration tank has an extremely bad odor gas, when it is a liquid with a strong acid originally, for example, in the sewage of ham, sausage, and fish processing, it is an alkaline water liquid in the cathode chamber of the diaphragm electrolysis. When neutralizing and mixing the anolyte sequentially and stopping the addition when the PH value is neutral,
The concentrated tank liquid becomes odorless due to deodorization, but most of the sulfides in the scum are electrolyzed by diaphragm using saline solution as electrolyte, and chlorine gas that generates an anode chamber is blown into the alkali of the cathode of diaphragm electrolysis soda hypochlorite. The sulfide is sulphated and deodorized. In the case of water containing a lot of ammonia, ammonia is adsorbed by activated carbon in the cathode chamber for deammonia, or deodorization is performed by diaphragm electrolysis with a different electrolyte that is neutralized with sulfuric acid solution of the anode to make ammonium sulfate. It is also a purification method that is performed. In particular, it is characterized in that it is treated as a neutral liquid by eliminating the pollution by combining the ultraviolet irradiation and the blowing of ozone gas. As described above, generally known sewage treatment and industrial wastewater treatment are performed by first separating water and separating solid matter with a screen, and then putting it in a waterfall tank to put anaerobic and aerobic bacteria and exposing it to the air. Is circulated by a pump to hydrolyze, and the supernatant liquid treated for 12 to 18 hours is discharged while mixing fresh water, and the concentrated liquid is sent to a concentrated tank by a pump and a flocculating agent is put into the concentrated tank to cause precipitation. Was separated with a centrifuge and the soot was sent to a water tank to dehydrate and incinerate the solid scum cake, or it was fermented as a soil conditioner and deodorized for use. The sludge method is not only used as a large-scale treatment method for wastewater treatment of many factories, but is also widely used for urban sewage treatment and drinking tap water. On the downside, the bad smell in the waterfall tank spreads to the surrounding area, so residents in the vicinity oppose the installation because of the pollution gas source. Since the same result occurs when it is exposed to air, many workers retire, and the bad odor is removed by sucking off the bad odor gas into the deodorization tank of activated carbon. This method has improved the problem that the deodorization was difficult to be performed because it was necessary to take in. An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an electrolytic cell (4) with a direct current of 50 V or more from a power source (k).
Electric power of 2 Amp is applied to the diaphragm electrode anode (3) and cathode (3 ') from the conductors (2) and (2') to electrolyze the diaphragm (1) in the electrolytic cell (4). As the electrolyte, salt or 10-25% calcium chloride solution is used. Cl and 2 accumulated on the upper part of the anode (3) are adsorbed on lime in the lime emulsion circulation tank (5). And the secondary electrolyzer (7) through the pipe (6)
Then, the anode (3) is isolated by the diaphragm (1a), and the electrolyte is electrolyzed at the cathode (3) by introducing the alkaline aqueous solution in the cathode (3 ') chamber of the primary electrolysis cell (4) through the pipe (6'). I do. And
Cl2 gas is blown into the electrolytic alkaline water in the chamber of the anode (3) from the pipe to form Nacl and Nacl.
Further, the electrolytic solution in the primary electrolytic cell (4) is introduced into the deodorizer tank (8) by the pipe (6 ″) and the acidic hydrochloric acid hypochlorous acid and the saline solution are flowed down through the perforated plate (9) to the lower part. The pipe (10) is blown upward with a bad smell of fecal sewage, washed with water, and the sulfide is oxidized with sodium chromate soda or water containing hypochlorite to change ammonia into ammonium chloride. Pipe (1) The secondary filter (12) is used to filter and the deodorized activated carbon is sent to the water vapor tank (3) and used as oxidizing air.The air vapor tank (3) is shielded by the canopy (14), and the tank (15) is used. ) From fermentative aerobic and anaerobic concentrates, sake yeast and papaya enzyme in a tank (1
5 ') is sent to the water vapor tank (13) and circulates the water vapor tank liquid with pipes (17) (17') connected to the pump (16) to vaporize the water, and the tank (18) is supplied with sodium carbonate and excess sodium carbonate. Water is added for 8 to 10 hours while deodorizing while adding sodium oxide, and the supernatant liquid (19) flows into the supernatant liquid precipitation tank (20) and the clear liquid filtered by the filter (21) is purified water. It is diluted with and released. The concentrated concentrate concentrate (20) deposited on the bottom of the water vapor tank (13) is concentrated by a pipe (24) (24 ') connected to a pump (23) to a concentration tank (25).
It is then sent to and deoxidized by adding sodium peroxide, oxygen gas, ozone gas or by electrolytic oxidation, and dehydrated by a centrifuge (26) to separate the scum cake as a paste, and the scum cake is oxidized by a high-voltage electrolyzing enzyme. Deodorize, mix with bark, sawdust, leaf and other plant fibers, bentonite, zeolite, humic acid, moss, etc. and add enzymes and yeast to ferment to make organic fertilizer, half of which is regenerated fermented fiber as inoculum And sell half of it as organic fertilizer. The filtrate separated by the centrifuge (26) is returned to the waterfall tank through the pipes (28) and (28 ') connected to the pump (27) and reused as the waterfall liquid.

FIG. 2 shows the deodorized air from the filter (12) sent to the waterfall tank (13) through the pipes (12 ′) and (12 ″) to a spray connected to the upper part of the pipe (12 ″). The upper casing (31) of the aspirator (30) is sucked from the side surface of the casing (31) to the center of the aspirator (30), and the nozzle is ejected from (30 ') to the lower tank (32) onto the upper surface of the water vapor tank (13). Space surface (30'a) on the side of the suction device (30) to enter
6-1 through thin tube (33) (33 ') to (30 "a)
The compressed air of a 0-atmosphere turbo fan or compressor is press-injected, and is injected to the lower part just before the lower nozzle.
Then, the ozone water (36) irradiated to the upper tank (34) by the ultraviolet lamp (35) is introduced from the pipe (37) into the center of the upper surface casing of the aspirator (30) to remove deodorization in the water tank. Introduce it to sewage. This high pressure oxygen generator (37) has 1
It is composed of a diaphragm electrolysis cell of 00 atm and is constituted by a stainless steel fuel-bonded membrane. Then, the oxygen gas generated in the anode (40) is adsorbed by the oxygen adsorbent and then introduced into the tank (34). The catalyst (39) is a hydrogen gas catalyst and is composed of manganese, nickel and cobalt catalysts, and the generated hydrogen gas is discharged from the catalyst (39) chamber through the suction discharge pipe (40). Ozone is generated by silent discharge in the ozone generator through the oxygen gas catalyst (38), and ozone is generated in the electrolytic cell (37) of the oxygen gas generator.
The liquid produced by the silent discharge is further sterilized by ultraviolet light and sent into the waterfall tank together with the blast air. Water tank (1
The contact air of 3) is deodorized when there is waterfall, but the scum cake can also reduce the waterfall time from 18 hours to 8 hours by inhaling this high-pressure oxygen gas.
In 100 atm high-pressure electrolysis, the electrolysis efficiency is 10 times as high as the transport number of ions, so that the production is increased, and at the same time, when scum cake is put into the autoclave (42) connected to the pipe (41), high-pressure oxygen is injected. Is about 1 at 10 bar
The bad odor is deodorized in 0 minutes, fermentation is almost odorless, and the forest odor β
Treated with a pinene odor. Also, in this fermentation, 1000 kg of water was added to 100 kg of bentonite to obtain glucose 2
0 kg salt 600 g, potassium phosphate 1.3 kg, ammonium phosphate 1 kg, yeast yeast with lactic acid bacteria, fermented and grown 100 kg of bark, 100 kg of scum cake, and mixed to pile up When the temperature rises to 90 ° C and heat is generated and the water content is 85%,
Since the amount of nitrogen is reduced to 70% and the nitrogen content is generated as ammonia gas, when neutralized with the anolyte that has been subjected to diaphragm electrolysis with the electrolyte solution (iron mirabilite iron anode), a large amount of actinomycetes of iron bacteria is produced. Mixing this with a rare earth element having radiation properties, particularly yttrium, lanthanum, cerium, or a metal salt containing uranium, thorium, or radium, chitosan becomes water-soluble in the continuous cropping disorder and prevents the continuous cropping disorder. As described above, the present invention uses the nighttime electric power by the diaphragm electrolysis to pollute the bad smell, so that the cost is reduced. Further, the use of the redox product by the electrolysis product can deodorize the malodorous gas and the malodorous sewage and promote the aggregation, so that it is also applied to the deodorization of the toilet of the train. That is,

[Fig. 3] The upper diagram shows the layout of the toilets inside the train.
A men tank (50) attached to the bottom of the train shows a urine water tank, and a storage tank (51) shows a tank (51) for storing manure and waste water. The water liquid on the upper surface of the tank (51) is separated as a supernatant liquid to be used for washing in a flush toilet, that is, (52a) to (xz) only the supernatant liquid is circulated and used as a cleaning liquid in the toilet bowl. Used for. As for this washing liquid, the supernatant liquid is transferred to the tank (50) and used as washing water for the urine liquid by the pipes (5) by the pumps (54) (54 ').
5) It is sent from (55 ') to the toilet urinals (53a) to (53M). Human toilet (53a) to (53M) of this train
Is deoxidized by being oxidatively decomposed and deodorized in the electrolytic cell (54) by neutralizing with an alkaline electrolyte. The deodorization carried out by such a method does not have a bad odor, since the deodorizing action is continuously carried out by the oxidation-reduction method even if it is circulated for 10 days or more. Conventionally, sludge in trains has been treated with calcium hypochlorite, lime, colorants, and powders to deodorize, so there are many problems in storing sludge in tanks for one month. Although it is discharged to the station building with treatment equipment for comprehensive treatment, optional treatment at each station building is limited where there is no treatment equipment, so treatment inside the train is more important and concentration by high-voltage electrolyzer It is necessary to deodorize with oxygen. Then, by the diaphragm electrolysis method using salt, the malodor of sulfide is oxidized by sodium hypochlorite and the ammonia is neutralized by an acid solution, and further, the decomposition products of organic acids and proteins are treated by alkalinity and merged. After deodorization, fermentation with oxygen prevents secondary pollution and simplifies any activated sludge system. Next

FIG. 3 shows an aqueous solution of the supernatant liquid tank (50) shown in Fig. 3 which is an electrolytic cell (50K) suspended in the supernatant liquid tank (50).
While the diaphragm (50E) is isolated, the anode (3) and the cathode (3 ') are inserted, DC power is applied to both electrodes from the power source (K), and a 300w ultraviolet lamp (S) is irradiated as an electrolytic solution. Pump (50C) to pipe (50d) (50'd)
Put the filtrate of the supernatant of urine water into the anode (3) chamber by
The pipe (50g) (59,
According to g), the filtrate of the supernatant of urine water is introduced into the cathode (3 ') chamber, and a small amount of caustic alkali or alkaline carbonate is added to salt or salt cake for electrolysis. Next, the rotation of the pump is adjusted with a synchronous motor and the flow rate is 500 to 1000 cc per minute.
Overflow to about 50P
The solution subjected to anodic electrolysis from (50'p) and the solution subjected to cathodic electrolysis are allowed to flow out to the supernatant (in the undiluted solution) over a period of time.
A pump (50s) (50's) is attached to this supernatant by a partition plate (50M) fitted in the center of the tank (50).
Depending on the pipe (50P) (50'p) and (50L)
(50'L) is an acidic oxidizing solution in which each solution is circulated and stirred to be electrolyzed, and an overflow of an acidic oxidizing solution and an electrolytic solution of an alkaline reducing solution (which has overflowed) are mixed and sterilized by the electrolytic solution. Sulfate the sulfide to neutralize the ammonia solution generated. Also, when the odorless reaction is carried out and the sulfated oxidation solution is neutralized with an alkali reducing solution and circulated as neutral salt water, the odorlessness is retained forever, so it can be used continuously for a long period of one month. Although it can withstand, it is harmless because it does not use a sterilizing material and is always discharged as a transparent liquid. And there is no secondary pollution due to the germicide. When this device is combined with fermented fiber to electrolyze the urine water solution and use the electrolyte solution for washing, it does not have a foul odor, so not only can it be used as a household toilet bowl, but it can also be used as a public toilet in the park or horse racing. It is also used in fields and baseball fields. When the scum cake of fecal solids is sent to the fermenter and mixed with dry fermented fiber, dehumidification is performed by the huminated fiber and carbon powder in the fiber, and further oxygen is added to lactic acid bacteria and yeast of fermenting bacteria, especially papaya. When combined with pineapple root juice and fig milk lotion of enzymes and other protein enzymes, deodorization is performed along with fermentation and the malodor is 1
It disappears in less than 0 minutes. Also, even if the electrolyte is treated with alkaline water as high pressure oxygen, the scum cake is almost deodorized and does not cause pollution.

[Fig. 4] shows a side view of the dry fermentation device, and the toilet (6

When l) rotates and mixes the fermented bark and fecal paste and sends the mixture to the tanks (60b) (60'b), the mixture is added with fermentative bacteria from the fermentation tank (60m) (60'm). The screw conveyor (60

It is sent to the bottom of b), accumulated, and deodorized and dried in fermentation in the presence of air while being taken out sequentially from hoppers P (60n) (60'n). It is better to take this out after about 3 to 7 days. In addition, pile up and re-fermentation is performed. The fermentation fiber storage u-shaped tank (60a) (6a
0'a) screw conveyor (60
Fermentation is carried out in the u-shaped tanks (60a) (60'a) such that g) is rotated left and right to repeat forward alternation.
Then, the high-pressure oxygen electrolyzed by the diaphragm in the electrolyzer (60j) is caused to flow into the u-shaped tanks (60a) and (60'a), and the reducing gas is also similarly put into the tank. Since fecal sludge contains 5% of nitrogen component and 6 to 7% of phosphoric acid component, most of nitrogen component is decomposed into ammonia by fermentation and fixed nitrogen component is reduced to 0.8 to 1.8%. 6
% Nitrogen component becomes ammonia gas and diffuses in the air, so when injecting oxidation or acidity of the anode chamber that can be placed in electrolysis, when 2-10% sodium sulfate is used as the electrolytic solution, the sulfuric acid solution makes the anode the iron plate. Since it is formed together with iron sulfate, hydrogen sulfide and mercaptan are also decomposed by this acidic liquid, and the non-reacted product of mercaptan is oxidized and sulphated by peroxide and hypochlorous acid. However, in the fermentation, when hypochlorous acid is introduced, it becomes bactericidal and often stops the subsequent fermentation, so further addition of concentrated bacteria is required, or an acidic liquid rich in sulfate ions or high-pressure oxygen gas is injected from the beginning. It is common to deodorize by.

[Fig. 4] In Fig. 4, a product with a water content of 60%, which is close to a dry state, is always used for fermentation, impregnation with water of about 95% is performed, and with a water content higher than that, fermentation does not delay and the temperature does not rise. A good way is to adjust the water content with a screw conveyor. In the case of this fermentation, to deodorize ammonia, use dry aldehyde of bamboo dry distillate, organic acid ester, binene aromatic compound, and soybean protein dry distillate to disperse the water to complete deodorization of ammonia. Done. When such a dry fermentation method is adopted, fecal sludge from trains, cars, buses, airplanes, etc. is decomposed in an anhydrous state, so river pollution is caused by the heat of fermentation of sewage flowing at 60-80 ° C. Since it is evaporated, it is not polluted at all and has the characteristic that it does not generate a bad odor. Most of the current treatments require a huge amount of equipment cost because it is necessary to prepare a dilute solution of 40 times more water to treat fecal sludge, and a large amount of deodorant is required to remove malodor, so it is never a rational treatment. This is not a law, but when treating relatively fresh excrement such as in the toilet of a train, the decomposition of rot has not progressed so much, so the cause of the foul odor is mostly organic substances such as valeric acid and indole pollutants. Most of the gas is simplified with only a small amount of digestive and physiological fluids, so direct membrane electrolysis of urine water also has a bactericidal effect, and a malodorous gas such as hydrogen sulfide or mercaptan which is a secondary malodorous substance. It is easy to deodorize since it is rare. When the generated gas of high-pressure oxygen is treated in a high-pressure tank of 10 atm, it is deodorized in about 10 minutes. This electrolyte is also used to maintain the freshness of plants. Therefore, it suffices to perform the treatment while suppressing the fermentation by ultraviolet irradiation, and the combined use of ozone gas is more effective. If the fermentation treatment is performed in this manner, the fermented product is used as a fertilizer for home gardening and also as a fertilizer for park roadside trees. Especially in long-distance transportation on trains, since the deodorization of the positive and negative electrode chambers of the diaphragm electrolysis method and the deoxidizing acid and alkaline liquid simultaneously deodorize the atmosphere and solids, there is no use of harmful chemicals. Not only does it not cause the next pollution, but it also has the benefit of not polluting the water quality of Lake Biwa and causing less harmful plankton. During fermentation, paper and other fibers are mixed with the fermented material and processed, and rubber and plastic impurities are separated by the removal screen, so it does not become a huge product of the fermented material and the processing cost is active. In the sludge method, 1 ton treatment costs 15,000 yen, but 1 ton is compressed to about 800 yen.
It is an industrially useful invention because there is no secondary cleaning cost for river water. An example of the composition of this electrolytic solution is as follows.

[Example 1] Salt 5% Caustic 1% Water or urine water 93.97-94% Sodium chromate 0-0.03%

[Example 2] Glauber's salt 5% Salt 0.1% Water or urine water 94.9%

[Example 3] Caustic soda or carbonated soda
5% water 95%

Example 4 Calcium lactate or organic acid salt 3
% Salt or Glauber's salt 5% Tea, bamboo or soybean dry distillate 0.03% Water or urine water 90-92% Others (Clo2, water, chlorate) The above example is a hypochlorous acid generating electrolyte and the diaphragm is Fluorine resin film, polyamide, amylan porous film Voltage 5 to 1
00volt Current density 0.1-1 Ampere Anode Titanium metal surface Platinum plating, Silicon manganese metal, Silicon alloy electrode, Cathode are similar, but stainless steel electrode is also used

In Example 2, an iron plate is used to enhance the decomposition and cohesiveness by iron sulfate ions and accelerate the oxidation reaction, but the water quality deteriorates when the iron ions increase, so it is used at a concentration of 0.1 to 5%.

Example 3 is a high pressure oxygen generating diaphragm electrolyte.

[Example 4] shows an electrolytic solution for a train, in which a dry-distilled product of tea, bamboo or soybeans was used while being dried at 300 to 400 ° C while rotating a high aluminum ceramic circular tube. Since this dry matter stops fermentation, it is used only for electrolytic deodorization, and the dry matter of Japanese cypress and cedar is also used for deodorization. The advantage of adopting this diaphragm electrolysis method is that the automatic restriction when detecting bad smell gas using gas clastography or sensor does not require much labor cost when combined with electric diaphragm electrolyzer. The dynamic soft circuit is easy to set, especially when using a water solution containing salts as the electrolyte solution after separating the supernatant of the contaminated water, the component system changes each time, so the automatic electrolysis during constant electrolysis is performed. Not only is it possible to control, but it is convenient to automatically control the addition amount of the redox liquid when a malodorous gas is detected. In addition, there is an advantage that electrical control can be easily performed even with respect to an electrolytic solution selection command particularly in diaphragm electrolysis. In this electrolysis process, when a maximum current of 2 amperes was applied at a voltage of 50 volt, it started from 0.1 amperes and started to rise to 1 ampere in about 15 minutes. The electrolysis temperature rose to 80 to 90 ° C and the current density gradually increased. However, when electrolysis is performed at a rate of 1 liter per minute while continuously discharging the stock solution (electrolyte), a titanium platinum plating electrode having an area of 10 cm × 20 cm × 0.1 is fluorinated resin film. When electrolyzing, the current density is 0.1 to 0.3 on average.
Become ampere. The current value when flowing down 100 cc / min of the electrolyte solution in the anode chamber rises to 0.5 amperes. Further, if the concentration is increased, the current value becomes proportionally large. 250-300w to electrolytically deodorize 1 ton of urine water
It consumes electricity per hour. As described above, the feature of the present invention is that the gas is washed with the oxidizing acidic liquid of both polar chambers formed by diaphragm electrolysis and the deoxidization is performed by reducing water with an alkaline reducing liquid to deodorize, and the oxidizing acidic liquid and the alkaline reducing liquid are converted into sludge aqueous liquid. After separately treating and performing sterilization oxidation and alkali neutralization to deodorize,
Using an organic fertilizer dehydrated by fermentation as a fertilizer to prevent pollution of the river without draining sewage into the river, combining electrolytic method and fermentation method, toilets such as trains, cars, buses, airplanes, etc. It is a deodorizing method that prevents runoff of manure and sewage from parks, roads, theaters, racetracks, and household sewage. In addition, since there is no use of bactericidal pollution chemicals and the decomposition treatment of pesticides etc. is pollution-free by the electrolysis method and fermentation method, it is also used for drainage of golf courses and also for the prevention of continuous cropping failures. The invention is useful for hygiene.
