と次の如くである。The present invention is a conventional activated sludge method in which the odor pollution of sludge of sludge of general livestock, fisheries and agricultural products and its processing wastewater is deodorized by oxidation by electrolytic dialysis, dealkalization is performed by cathodic reduction, and this is recovered. Aeration tank for purification of odorless effluent, concentrating tank After centrifugal separation, the sewage in the filtrate is electrolyzed by this electrolytic dialysis method to deodorize, and the deodorant solution is treated with dealkalized ammonia and desulfurization. By reusing it as a diluted aeration liquid, deodorizing and fermenting sludge and scum cake with fermenting fiber and processing it as a fertilizer, part of which can be used as a fermentation material to reduce the amount of water used. A method for improving the activated sludge process that improves secondary pollution by electrolytically removing ammonia, amines, oxides, and organic acids that cause bad smell pollution and reduces treatment cost by 30% or more. That is the content. The activated sludge method was the general treatment method for most wastewater treatment. In this method, first, after sewage is screened, degreasing is carried out by a floating method, this is introduced into an aeration tank, and a decomposed seedling in which anaerobic bacteria and aerobic bacteria are mixed is added, while blowing air. The waste water is circulated to separate the supernatant after decomposition, the scum cake at the bottom is sent to a concentrating tank, and the supernatant is diluted with water to give B.I. O. D
Is 5 to 20 P. P. The liquid in the concentrating tank to which the concentrated liquid at the bottom discharged as M or less is transferred is separated into scum cake and filtrate by a centrifuge, and the scum cake is also as industrial waste.
Besides being used as a soil conditioner, it is incinerated in an incinerator. This separated liquid is returned to the aeration tank and reused as an aeration liquid, but decomposition in this aeration tank gives off a bad odor during aeration.
There was air pollution. Further, even in the concentrating tank, odorous substances such as amines and sulfides were emitted in sewage containing a lot of protein, and also in the scum cake, an odor was emitted, which was a cause of pollution gas. In addition, enormous equipment costs and large land are required for this equipment, and it is about 2 in the case of an urban housing complex with a population of about 7,000.
An investment of 500 million yen was required, and not only was it costing 500 million yen to treat sewage for 10,000 pig houses in a pig farm, but the management cost for each pig was 15,000 yen. The bad smell pollution increased, and the improvement of the treatment was demanded. The reason for this high cost is that the treatment capacity is increased to 40 times the volume by increasing the flush water by using about 40 times as much washing water as that of the manure. This increase in capacity also caused an increase in the amount of malodorous gas generated, which caused secondary pollution. Therefore, as a method of reducing this amount of water, it has become possible to mix wood, bark, saw tools, and fiber waste with knot meal of external paper and perform fermentation treatment by the action of fermenting bacteria. Due to a decrease in the amount of processed timber imported and the difficulty in securing sufficient amounts to process these,
The securing thereof is limited, the cost is increased and the cost for drying and odor treatment is increased, and better improvement is required. Therefore, as a method of reducing this treatment cost and eliminating the foul odor pollution, in the conventional activated sludge method treatment by aeration, when a large amount of coexisting water is treated by the electrolytic method, an alkaline water solution is used. Acidic aqueous solution is generated, and in acidic aqueous solution, bacteria, Escherichia coli, cholera, typhoid, and Shigella are sterilized at pH 3.5 or less, and the fermentation action works for up to 10 days after electrolysis. There is a feature that does not. In addition, the generation of offensive odor gas can be stopped by concentrating and recovering the alkaline trimethylolamine, ammonia, and soda potassium in the alkaline water solution. In particular, most of the electrolytically oxidized water is odorless, but a small amount of NCL can be added to the sludge to improve sterilization.
When adding, chlorine sterilization and oxygen sterilization are simultaneously performed, and odorless valeric acid, oxalic acid and other organic acids and sulfur oxides are also oxidized and deodorized. Moreover, this electricity bill deodorizes 1 liter of liquid with 0.3w. Therefore, it becomes 300w per ton. When this deodorized sewage circulates and is used as an immersion liquid in undegraded sludge scum cake or sludge, the strong odorless scum cake or sludge is covered with odorless sewage and changes to odorless. While the electrolysis continues, the malodor of the whole sludge is suppressed. Also, this deodorized sludge does not produce a bad odor even if it is left standing for about 10 days, so it is sufficient to automatically operate the electrolysis with a timer operation. Also, when a bad smell gas sensor is used, If the electrolysis is continued, the malodor will disappear. This also applies to aeration.
When performing oxidation and bacterial decomposition while aerating sewage,
Since all of them are filled with malodorous gas, this aeration gas is passed through alkaline water solution or acidic water solution, and the dispersion is washed with sodium chromate soda granules or the same ceramic adsorbent to purify the gas and make it odorless. There is also a method, but when the amount increases or the temperature rises, it is not easy to deodorize the malodorous gas, and finally it is deodorized by adsorbing activated carbon. Therefore, these costs are not stupid. For example, when the running cost per 1 ton of pig feces described above is 15,000 yen, it takes 3 minutes to deodorize 200 cc of 300 w in the present electrolysis method, resulting in 0.3 w. If kw / @ ¥ 10, it will be about ¥ 3. Therefore, the deodorizing cost of the malodorous gas is out of the question. 2 out of the number of bacteria in this electrolytic wastewater
Since all except the type are sterilized by electrolysis, it is thought that when this is mixed with sludge solid matter, the spontaneous decomposition of the solid matter may be suppressed, but anaerobic bacteria in the solid matter are compared. Being healthy and active after the electrolysis ends, the malodorous organic acid reacts with ammonia ions and other alkali ions to reduce the generation of malodorous gas and maintain the equilibrium relationship. Become. Therefore, the consumption of electrolysis power is not required as much as expected. These are also used for sludge treatment in barns and similarly for chicken manure treatment. It can also be applied to wastewater treatment of sausages, ham factories and fisheries processing plants in livestock processing. For example, drainage from a sausage factory first removes sludge by screening to separate SS sludge from drainage, and when it is placed in an aeration tank, the pH of the drainage is 2 to 2 due to the presence of a large amount of protein. It will decrease to around 4, and complaints of bad odors will always be received from suburbs due to the bad odors of rugs, amines, and ammonia, but since rugs are converted to sulphides by electrolytic oxidation, the odor of sulfide gradually disappears, which is a digression. Amine also has a bad odor of trimethylolamine, and is converted to ammonia, methyl alcohol, aldehydes, and chlorides to gradually eliminate the bad odor and become deodorized. When there are a lot of chlorine ions, it changes to chlorine gas odor, but it is gradually oxidized by this chlorine and peroxygen gas to become bactericidal and becomes odorless. However, when there are a lot of chlorine ions, the chlorine odor will become more intense, so this control can be handled with low voltage and low current. Generally 3-6
w, low power with current 0.03-0.1 amps is used. This chlorine ion also reacts with the peroxide of fatty acid and suppresses the generation of malodorous fatty acid, so that it is used for controlling the generation of malodorous gas. When this is neutralized with an alkaline solution for electrolytic reduction, it is soaped and enters the solution to further reduce the bad odor. When the aerated concentrated solution of sausage is electrolytically reduced, the PH value rises to 7 to 11, and the same effect can be obtained even if neutralized with caustic alkali or alkali peroxide. Butyric acid is produced in the drainage of sweet potato starch as a livestock feed by the hydrolysis of starch, but it is generated during aeration because the electrolysis of calcium lactate and sodium lactate prevents butyric acid from generating and oxidatively decomposes them. Not only is malodorous butyric acid and valeric acid suppressed and becomes odorless, but also the butyric acid in the wastewater of the feed for drinking sake lees is neutralized and deodorized by alkaline electrolysis, so the feed is always deodorized. To be These are also applied to livestock waste and marine waste, and deodorization is performed by washing the electrolytic solution with water. Therefore, it should be noted that in the electrolysis of sewage, a part of a mixture of caustic soda potassium, ammonia, and amine is produced in the alkaline electrolyte of the cathode, so the ammonia odor gradually increases with time. Blow into the salt and lime liquid for recovering the gas together with the carbon dioxide, and use the Sorbet method to make sodium carbonate, and then separate and collect the calcium chloride and ammonia mixed liquid, or absorb the ammonia gas in formaldehyde and recover as ultrapin. Then, the caustic is concentrated and used as a potassium raw material. Potassium is used for agricultural manure as chloride and potassium sulfate. For that purpose, it is economical to use caustic as a neutralizing agent and use a neutralized alkali salt. These applications are also applied to deodorizing treatment in horse breeding on racetracks, but also for cooking drainage and human excrement,
It is also used for fish processing waste, and also for seawater purification for shellfish and fish farming. An embodiment of the present invention will be described below with reference to the drawings.

The pH value of the sewage (a ') of the cathode gradually changes from neutralization to alkaline, the caustic soda caustic potash, ammonia and amines increase, the organic acid decreases but the ammonia odor gradually increases.

a ') is processed and fitted, and the cylinders (4a) (4
a ') is used as a diaphragm cylinder, and electrodes (2) and (2') are inserted into the cylinders to make sodium lactate, salt and sodium mirabilite solution (a) solution as electrolyte solution, and the catholyte solution (a ') is also added. When sewage (a) is put into the water tank (1a) and electrolysis is performed by applying a voltage, the organic acid in the sewage enters the anode chamber, chlorine and sulfate both enter the anode, and oxygen is partially chlorine. With this, chlorine gas and sodium hypochlorite are formed. Then, the concentration of soda potash and ammonia in the sewage (a) along with the amines gradually increases in the cathode, and the PH value exceeds 11. The pH of the anode also decreases from 7 to 3 to 2 and becomes acidic, and the malodorous gas of the malodorous wastewater (a) gradually decreases. Therefore, the dirty water (a) is introduced into the diaphragm cylinder (4a) by the pump (8a), and the solenoid valve (5) provided at the bottom thereof.
The deodorized sewage (a3) that has been internally electrolyzed by operating a) is taken out to the outside, the sewage (a) liquid is replaced and the solenoid valve (5a) is closed, and electrolysis is continued for 3 to 20 minutes to electrolyze, In the same manner as described above, when the electrolytic deodorizing liquid in the diaphragm cylinder is replaced with the external sewage liquid to gradually electrolytically deodorize the sewage (a) liquid, the sewage (a) is completely deodorized. Therefore, the first anode diaphragm tube (4a)
When electrolysis is continued as it is with sodium chloride, mirabilite, and lactate water as the internal electrolytic solution, the organic acid in the sewage (a) is separated by the diaphragm cylinder (4
Chlorine, oxygen, hypochlorous acid are concentrated in the cylinder (4a) and chloric acid and hypochlorous acid in the wastewater (a) are reduced and transferred to the electrolytic cell (1a). Immediately when the anode (2 "a) is upright and electrolyzed, the sewage (a) is immediately deodorized, and the tube (4a) is deodorized and oxidized while the malodorous organic acid is concentrated in the tube. .or,
In the diaphragm cylinder (4a), the concentration of caustic alkali, ammonia, and amines increases, and the concentrated and concentrated alkaline salts, ammoniu, and amines of the wastewater undiluted solution (a) are reduced and purified. The stock solution (a) is circulated and used as substitute water for tap water.

脱臭される時間は1トンの汚水で3〜10分であった。[Fig. 6] The process diagram of Fig. 6 is a pig house (1c) (2c) (3) in a pig farm.
c) (4C), (5c), (6c) to (ηc) used as washing water is an odorless liquid obtained by electrolyzing the anode plate (1c) of this electrolytic cell from the tank (3'c) with the pump (2'c). To do. This anode chamber (A) is made of a porous film cylinder made of vinyl peroxide, polyamide, or acetyl cellulose, or a cylindrical container (4'c) made of ceramics or glass, which is electrolyzed and becomes odorless. ) Circulates the sewage in the electrolytic anode chamber (A) through the sewage in the electrolytic cell (6'c) and the electrolytic oxidant'c in the dialysis diaphragm tube (4'c) to produce the electrolytic cell (6'c). The sewage (B) inside is gradually deodorized to make it odorless. (7 '
c) (8'c) consists of an odorless gas sensor and a regulator. In order to quickly remove this malodorous gas from the wastewater (B), the auxiliary anodes (10'c) (12'c) are placed upright in the wastewater (B) for electrolysis, and the dialysis membrane (4'c).
Ammonia gas, caustic alkali, and amines are dialyzed and separated using (4 "c) as a cathode, and the sewage is sterilized by reducing the PH value to 3 to 2.5 by electrolytic oxidation. When there are a lot of odorless organic acids such as valeric acid and butyric acid, the diaphragm tube (4'c) is used as the anode chamber (A) for electrolysis by adding a small amount of salt or mirabilite to the electrolytic cell (6 ').
The wastewater (B) in c) is separated from the cathode (1) of another septum (4 "c).
1'c) and the anode (9'c) are electrodialyzed, but the electrolyte in the diaphragm cylinder (4 "c) is also in salt water (B) when electrolyzing as salt or sodium mirabilite. Since the negative ions of (1) are collected at the anode and the positive ions are collected at the cathode, the malodorous components in the sewage gradually collect in each diaphragm cylinder (4'c) (4 "c). Glauber's salt and salt in the diaphragm cylinders (4'c) (4 "c) are decomposed and caustic alkali, ammonia, and amine remain in the cathode chamber, and chlorine, hypochlorous acid, and silicic acid remain in the anode chamber. When the auxiliary electrode (10'c) is used as an anode and (12'c) is used as a cathode and the cathode chamber is wrapped with a diaphragm umbrella, the sewage (B) gradually eliminates a bad odor by oxidation and scum cake precipitate. Since (D) is deodorized, it is used as a washing liquid.The pipe of this washing water (13'c) is used for the tank (3 ').
The new sewage, which has been pumped to c), provided for washing, and washed with water, flows into the sewage (B) of the electrolytic cell (6'c) from the pipe (14'c), and electrolytic deodorization is repeated.
This electrolyzer has the same function as a known aeration tank that oxidizes sewage, but the conventional malodorous gas is deodorized within 3 to 10 minutes by electrolysis, and chlorine and butyric acid are generated by electrolysis, which causes the anode chamber. Is immediately deodorized, and even if the upper surface of the electrolytic cell (6'c) is sealed, no odor is generated because the oxidation is performed by the decomposition action of the anode. Therefore, there is no diffusion of the malodorous gas even in the presence of the malodorous gas for 3 to 10 minutes. Then, the precipitated scum cake is deodorized and screwed (15'c).
It is taken out of the tank and fermented. When a large amount of this sewage (B) is generated in addition to water washing, deodorized sewage (B) is discharged by capillary absorbent fiber (16'c) through pipe (17'c) and introduced into the diluter (18'c). Then, dilute it with tap water (19'c). O. Set D to 5-10 and release port (2
Release from 1'c). (20'c) is a weir that separates suspended matter. The sludge (D) of scum cake is introduced into the settling tank (23'c) by the pipe (22'c) and neutralized liquid is stored in the tank (24'c) by the pump (25'c). It is filtered by a centrifuge (26'c), and the filtered solution is electrolytically oxidized by an electrolytic dialyzer (27'c) and sent to a tank (28'c) by a pump (29'c) as diluted rinsing water. . The deodorized sewage in this tank (28'c) is used as a diluted water for discharge. In addition, the scum cake separated by the centrifuge (26'c) is loaded on the conveyor (30'c) and is mixed with another conveyor (30 "in the mixer (31'c).
After the sawdust fiber bark powder is loaded and mixed in c), the fermenter (31'c) is piled up and a mixture of air and generated electrolyzed oxygen gas is blown to perform fermentation. This fermentation is
Scum cake with a moisture content of 70-80% was mixed with 1 kg of fiber and 0.5 kg of pre-fermented humic acid fiber and fermented for 30 days. One half of this was used as fertilizer and the other half was fermented. It is used for fermentation by mixing with wood waste materials, knot meal, cottonseed husks, and rice husks mixed with fermentation concentrated bacteria in new fermentation as seeds, and fermented at a fermentation temperature of 70 to 80 ° C at room temperature of 25 ° C, and matured for 60 days. Use the fertilizer. In this electrolytic dialysis, a voltage of 1 to 5 V and a current of 0.01 to 0.08 amperes were used, but the power consumption per ton was 300 w to 500 w, but the total power was 3 kW. The time for deodorization by electrolytic oxidation was 3 to 10 minutes with 1 ton of sewage.

れ、二次公害の要因を作らない。As shown in Fig. 5, when a large number of turtles are sequentially absorbed and moved by a capillary absorber, the sewage is electrolyzed and deodorized while the electrolysis is sequentially performed, so that the sewage is separated from the scum cake in the sewage. Since it moves while being purified and electrolysis is performed, it improves the odor pollution by combining with the device of the conventional activated sludge method, so the diaphragm is also isolated if it is put on the electric ring of the capillary absorber. So (-) (-) (+) (+)
(-) (-) Sequential ionization and concentration, so scum cake remains in the higher turtles during sewage treatment of swine, and the amount of sediment decreases toward the end of the turtle. As a diluted electrolytic oxidation wastewater by introducing water, B.
O. 5 to 20P. P. Discharge at about M. In this method, since sewage is moved and purified by utilizing the self-propelled head, there is an advantage that equipment such as a pump is not required only for inclination, and an inexpensive device can be obtained. This facilitates a stable array of turtles, primarily using the slope of the mountains. Further, in order to further purify the sewage, the concentrated sewage separated into anions and cations can be further subjected to repeated electrolytic dialysis, and deodorization is sequentially performed to enhance the sterilization effect. Then, ammonia is easily volatilized and caustic alkali remains. Therefore, when this is replaced with a publicly known aeration tank, a result that less odorous gas is generated is obtained, and a factor of secondary pollution is not created.

されるので産業上有用な発明である。FIG. 3 is a side view of a capillary absorption electrolysis method, showing an inverted U-shaped glass fiber (4) on a 1l beaker (1e) (2e) (3e).
e) (5e) (6e) are inserted and auxiliary electrodes (7e) (8
e) Set (9e) upright and set it in a beaker, and put dirty water (B) in each beaker (1e) (2e) (3e). Then, this waste water (B) is introduced into the beaker (1'e) by the pump (10e), and the inverted U-shaped fiber (4'e) is introduced.
Capillary suction is performed by the beaker (1e) into the dirty water (B)
Introduce each DC battery into the electric ring (11e) (12e) (1
When electric power is applied to 3e) and auxiliary electrodes (7e) (8e) (9e), electrolytic dialysis is performed in each beaker to form an anode chamber containing many anions and a cathode chamber containing many cations. The (-) ion chamber is gradually separated from the (-) ion and the (+) ion group, and the (-) ion chamber gradually loses its malodor. Therefore, insert the siphon tube (14'e) into the beaker (1e) and insert the beaker (15e).
When a liquid containing a large amount of anions is introduced into, the malodorous gas is deodorized and oxidatively decomposed to become odorless. When this is further electrophoresed by attaching an electric ring to the capillary absorbent fiber, the wastewater is further deionized to promote deodorization purification. When this anodizing liquid is introduced into the aeration tank of waste water, generation of malodorous gas is gradually reduced. When the cathodic reduced sewage becomes an alkaline liquid and is separated and concentrated, it serves to degrease the sewage and serves as a raw material for alkaline soap, which is recovered as potassium fertilizer. Sulfide undergoes cathodic oxidation and is sulphated and deodorized. In applying this electric power, electrolysis is performed at a low voltage of 1 to 5 V and a small current of 0.01 to 0.08 amperes. The pH of the anode becomes acidic in 3 minutes, and the pH value reaches 2.5 by adding Glauber's salt or salt. For example, with 0.5% saline solution, the PH value becomes 2.5 in about 10 minutes, so sterilization is performed at the same time, and it is used as washing water in a general dining room and does not generate offensive odor gas from the wastewater, but the sludge is previously generated. Need to separate on screen. When this anode water is used as sewage, the growth of bacteria in the sewage is suppressed, so the sewage obtained by diluting salt water with acidic water obtained by electrolyzing it becomes odorless. Alkaline water can also be used as washing water by reacting hypochlorous acid with it to form an alkaline solution with strong bactericidal activity. Further, the neutralization of the acidic liquid in the anode can release it as neutral, so that secondary pollution can be prevented in advance. In addition, diaphragm electrolysis and capillary absorption electrolysis, that is, when the glass fiber bundle is formed into an inverted U shape, and when sewage is flown into the fiber, for example, when attaching an anode to the inlet and separately electrolyzing with an auxiliary cathode, When the acidic deodorized sewage flows during capillary absorption, and the sewage electrolytically reduced at the cathode first flows,
The alkaline wastewater flows into the next beaker and becomes alkaline water in the beaker, which is used for alkali recovery.
When the odorous odorous gas from the wastewater is washed with the acidic water solution and the alkaline solution, the odorous gas is deodorized, so that the odorous gas is also used for separation. Therefore, this deodorization by electrolysis automatically removes the malodor of the publicly known malodor by electrolysis, and the malodor of the aeration tank, the concentration tank, and the separator is automatically removed. The bad odors and sulfidic odors of amines due to automatic acidic water are first completely neutralized with an alkaline electrolysis solution and subjected to oxidative electrolysis to completely remove odors, and secondary pollution of livestock processing and marine products processing is eliminated. Since this electric power does not use high voltage and high current unlike the conventional electrolytic dialysis, power consumption is small and deodorization can be obtained extremely economically. In this general electrolytic dialysis, 24 to 35 kW for purifying 1 ton of sewage
It is advantageous to increase the practicality that the required amount is suppressed to about 1 kW. And, the combined use of diaphragm and capillary absorption reduces the use of pump power and reduces general administrative costs. As described above, the features of the present invention are that, in order to reduce the bad smell pollution in livestock pollution and fishery products, processed livestock products, and processed food wastewater, general activated sludge method aeration tank, concentration tank, separator tank Most of the bad odors generated in the inside can be easily removed by using the electrolytic oxidizer and the source of the bad odor can be prevented. In addition, the electrolytic treatment by this electrolytic dialysis or ion exchange membrane is the most rational for the removal of ammonia ions in the waste water. It is effectively deammonified and can be removed by, for example, arranging a large number of diaphragm cylinders in an electrolytic cell, which is effective in deammonifying drinking water and is also used for regeneration of activated carbon. In particular, it is possible to install a small and compact electrolytic oxidizer as a deodorizer outside the kitchen drainage and sterilizing and washing liquid, and inside the outlet pipe of the sink, so it is also effective for comprehensive purification of drainage and for sterilizing and sterilizing containers. It can also be used as a fertilizer by fermenting contaminated scum cake, and the deodorization of the scum cake by electrolytic anodizing liquid in fish processing is also used as a feed ingredient in food processing. It is an industrially useful invention because it is widely used for fecal tests in hospitals.

排水汚水処理法。As described below, as deodorization of wastewater in general activated sludge treatment, the wastewater sewage is immersed in a sludge tank in a porous filter container made of multiple plastics or ceramic glass, or
Immerse the glass or plastics fibrin in sewage, insert the Yin and Yang electrodes, electrolyze in the sludge tank, and return the sewage deodorized by anodic oxidation to the original sewage for a certain period of time, and then the new sewage Introduces electrolysis and controls this with a solenoid valve and a sensor to make the entire sewage odorless and deodorize the stench scum cake and sludge in the sludge tank.The sludge is removed from the tank with a screw. It is taken out, dehydrated, mixed with fiber with fermented gold, fermented and decomposed to make it a fertilizer, and the dialyzed alkali and ammonia are concentrated and deodorized and collected, and ammonia gas is heated and volatilized to collect carbonic fertilizer and resin. B. used as a raw material and after aeration by the activated sludge method. O. Similarly, water containing a small amount of D was subjected to deammonification and desulfurization by electrolysis and discharged, and then filtered with a scum cake or screen remaining at the bottom of the aeration tank. The malodor produced when the concentrated S sludge sewage solution is transferred to the concentration tank is also deoxidized by electrolytic oxidation to perform deammonification, and the odorous sewage is dehydrated by a centrifuge to use solid scum cake as a fermentation raw material. After electrolyzing in the electrolytic cell to perform deammonification and desulfurization, it is returned to the aeration tank, mixed with decomposing bacteria, and then circulated and used in the aerated decomposition solution, while the caustic alkali, ammonia, and sulfides separated during that are used for electrolytic recovery. A method for treating wastewater from livestock, fisheries, and agricultural products, which is characterized by purifying and deodorizing sewage for reuse.
