2. Description of the Related Art In recent years,
The pollution of the atmosphere, rivers, lakes and marshes due to exhaust and drainage has become a serious problem as environmental destruction. Among them, considering the pollution of rivers, lakes and marshes by the drainage, there are various types of drainage and various regulations are set. For example, for agricultural village drainage, the agricultural village drainage project implementation guidelines (April 1983)
The Ministry of Agriculture, Forestry and Fisheries (Secretary for Agriculture, Forestry and Fisheries) has been formulated, and the purpose is as follows.

Due to changes in the circumstances surrounding agriculture and rural areas such as the progress of mixed living in rural societies, the sophistication of lifestyles, changes in agricultural production styles, etc., the pollution of agricultural drainage has progressed, and the growth of agricultural crops has been impaired. There are major problems in both the agricultural production environment and the rural living environment, such as increased maintenance costs for land improvement facilities and the generation of offensive odors. Therefore, in order to maintain the water quality of agricultural drainage, maintain the functions of agricultural drainage facilities or improve the rural living environment, and contribute to the water quality conservation of public water areas, human waste in agricultural settlements, domestic wastewater, etc. The facility for treating sewage, sludge or rainwater will be developed.

In addition to such agricultural village drainage, drainage from livestock such as pig farming, general household miscellaneous drainage, factory drainage from food factories, semiconductor manufacturing plants and other factories, leisure drainage from golf courses, etc. , There is a wide variety of wastewater around us that needs to be improved to above a certain standard. Moreover, these wastewaters have different components to be treated, such as human waste, chemical fertilizers, detergents, household oils, etc.
There are various purposes and effects of water quality improvement such as deodorization, oil decomposition and sterilization.

However, in order to effectively improve the water quality for such various effluents, a large-scale and complicated effluent treatment facility is required for each purpose, and the cost of the effluent treatment is high. There is a problem of becoming.

Further, in facilities such as wastewater treatment, sewage treatment, sludge treatment, livestock farms, meat processing plants, etc., a large amount of gas containing hydrogen sulfide gas, ammonia gas and other malodorous components is generated. A device for deodorizing and purifying air is used. As a device conventionally used for deodorization, there is, for example, a device for absorbing and removing a sulfur compound by bringing a gas containing hydrogen sulfide, which is a main component of a malodorous component, into contact with an alkaline aqueous solution.

However, in the case of deodorizing by such an alkali cleaning, when caustic soda is used as the alkaline cleaning liquid, carbon dioxide absorbed in the cleaning liquid reacts with caustic soda to be changed to sodium carbonate or sodium bicarbonate, resulting in efficiency (removal). Rate) decreases. Therefore, in order to maintain the desired efficiency, it is necessary to supplement the caustic soda, and it is difficult to maintain sufficient hydrogen sulfide removal efficiency. Further, as a method for removing a trace amount of sulfur compounds that cannot be completely removed by alkali cleaning, an activated carbon adsorption method, an ozone deodorizing catalyst method, or the like is employed in combination.

Therefore, in order to efficiently remove the sulfur compound from the periodic component-containing gas mainly composed of a sulfur compound such as hydrogen sulfide, the sulfur compound is brought into contact with an aqueous solution of sodium carbonate containing zinc salt as an alkali cleaning liquid to form a sulfur atom in the sulfur compound. A method of separating and removing as zinc sulfide has been proposed (for example, Japanese Patent No. 2731124). According to this method, it is necessary to maintain the content of the zinc salt in the aqueous solution of sodium carbonate at 3 times or more as an equivalence ratio with respect to zinc sulfide accumulated in the aqueous solution as a suspension and a precipitate. Special consideration is required for adjusting and maintaining the content of zinc salt.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of a water catalyst treatment device of a drainage treatment system using catalytic water of functional ceramics according to the present invention, and FIG. 2 is a drainage treatment using catalytic water of functional ceramics according to the present invention. It is a figure which shows the embodiment of a system. In the figure, 1 is a processing tank, 2 is a granule of functional ceramics, 3 is a basket, 4 is an air supply part, 5 is an exhaust part, 6
Is a water supply unit, 7 is a drainage unit, 8 to 11 are valves, 12 is an exhaust fan, 13 is catalytic water, 14 is a spray nozzle, 21 is a treatment tank, 22 is a wastewater treatment facility, and 23 is a sodium hypochlorite addition unit. , 24 is a catalyst water mixing section, and 25 is a treated wastewater extraction section.

In FIG. 1, the processing tank 1 has an exhaust unit 5, an exhaust fan 12 near the ceiling, a water supply unit 6 and a sprinkler nozzle 14 below the ceiling, and an air supply unit 4 and a drain unit 7 near the bottom. The baskets 3 each containing a plurality of functional ceramic particles 2 mixed therein are arranged in multiple stages. The water supply section 6 drips sodium hypochlorite (NaClO) as a drip agent into raw water with a valve 10 and supplies an aqueous solution of sodium hypochlorite having a concentration of about 1 to 3 ppm to the water spray nozzle 14 to feed the treatment tank 1 from above. To be introduced in. Drain 7
Is to take out the catalyst water 13 produced by the catalytic action when showering from the water spray nozzle 14 and passing through and contacting the plurality of functional ceramic particles 2, and through the valve 11, as shown in FIG. By taking out from the bottom at a predetermined height level, the catalytic water is stored in the treatment tank 1 up to the predetermined height level.
The height level may be, for example, half the number of stages of the basket 3, or the number of stages of the basket 3 in the catalyst water 13 and the number of stages of the basket 3 above the water surface of the catalyst water 13 may be appropriately set. Alternatively, the height level may be adjusted according to the number of steps of the basket 3. The air supply unit 4 supplies a gas such as a malodorous component-containing gas or other gas or air through a valve 8 and introduces the gas from the vicinity of the bottom into the stored catalytic water in the processing tank 1. The exhaust unit 5 exhausts the deodorized and purified gas through the valve 9 when the gas introduced from the air supply unit 4 comes into contact with the plurality of functional ceramic particles 2 and the catalytic water. The exhaust fan 12 sends the exhaust gas to the exhaust unit 5.

The functional ceramic granules 2 are obtained by using a resin or glass as a binder and sintering a ferrite-based material in which at least a magnetic material and a plurality of metal oxides such as iron, cobalt and titanium are combined. It is the first
Of the different types of particles having different component concentrations, which are composed of the above-mentioned granules, the second granules, and the third granules, are mixed and stored in the basket 3, and these are stacked in several stages (four stages in the illustrated example). It is arranged so that it can be removed and replaced. The first particles are at least a magnetic material based on ferrite,
The second granular material is formed by sintering a combination of metal oxides of iron, molybdenum, cobalt, titanium, magnesium, aluminum, potassium, zirconium, and silicon.
The ferrite-based material is a combination of at least a magnetic material and a metal oxide of iron and manganese, cobalt, titanium, magnesium, aluminum, potassium, zirconium, and silicon, and the third granular material is at least aluminum oxide, It is made by sintering a combination of metal oxides of zirconia, diatomaceous earth and barium titanate.

In these granules, it is possible to improve the efficiency of the reaction of ions by controlling the component concentration and changing the atomic percentage, and the first granule has a particularly remarkable effect on the sterilization and deodorizing action. It was confirmed that the second granules had a remarkable effect on oil decomposition and bactericidal action, and the third granules had a remarkable effect on oil decomposition action. Also, the first
When the granules of No. 2 and the granules of No. 2 are mixed, the first granules and the second granules react with each other because the component concentrations are different, and the efficiency of ion generation is improved. It has also been demonstrated that by adding a small amount of a third granule, oil decomposition is more advanced. In addition, the third granules have a strong coagulation action, form molecules in the form of flocs, and have the action of making the oil content hydrophilic and lipophilic. Therefore, the effect of increasing the sedimentation speed of sludge has been confirmed in many wastewater treatment plants. In other words, since it works better for organic decomposition, it contributes to the improvement of water quality,
It is connected to the improvement of the deodorizing effect by removing the oxidative odor of oil. This is based on many years of experience in repeated studies of functional ceramics and repeated tests, and the experience value determines the ratio standard of each particle by applying it to deodorization, water quality improvement, and the like.

Therefore, by controlling the component concentrations and changing the mixing ratio of the first to third particles, it is possible to enhance the effect according to the processing purpose. For example, a large amount of ammonia, hydrogen sulfide, nitrogen, phosphorus, etc. are contained in wastewater from livestock industries such as pig farming, wastewater from agricultural communities, and general domestic wastewater, and a deodorizing effect is particularly required. Further, with respect to factory wastewater including food factory wastewater and canteen and restaurant wastewater, a large amount of oil, nitrogen, phosphorus, etc. is required, and the effect of oil decomposition is particularly required. The mixing ratios of the first to third granules are set according to the respective requirements.

In the water catalyst treatment apparatus for producing the catalytic water of the functional ceramic according to the present invention, the aqueous solution of sodium hypochlorite is showered by the sprinkling nozzle 14 so that the granular particles 2 of the functional ceramic in the upper stage are sequentially passed and contacted. Further, it is stored below and is brought into contact with the granules 2 of the lower functional ceramic through the drainage section 7 to perform catalytic water treatment to generate catalytic water. Drainage part 7
It is taken out through the valve 11 through the valve 11 and added to sewage, waste water and sludge to be used as catalytic water for improving the treatment effect or improving the quality of water such as commercial water. On the other hand, the sodium hypochlorite aqueous solution was added to the functional ceramic particles 2 as described above.
Ammonia, dioxin, carbon dioxide (CO ₂ ), and hydrogen sulfide in the gas are removed by the catalytic water produced by passing and contacting with the dewatering agent, and deodorization and purification can be performed.

In the apparatus having the above construction, the aqueous solution of sodium hypochlorite flows from the upper side to the lower side in the processing tank 1 and passes through the functional ceramic granules 2 arranged in multiple stages to generate catalytic water. At the same time as it is taken out, gas flows from the lower direction to the upper direction in the opposite direction,
In the stored catalyst water 13, the gas becomes bubbles and rises between the functional ceramic particles 2 so as to oscillate and contact each other, and the dirt adhering to the functional ceramic particles 2 is removed for cleaning. It can be carried out. Therefore, by replacing the functional ceramic particles 2 between the upper stage and the lower stage from time to time, it is possible to maintain the state in the catalytic water 13 and the state above it in the same state.

The catalyst water taken out from the drainage section 7 is used as water in an agricultural settlement wastewater treatment plant, a treatment plant in the livestock industry, a breeding ground, a meat center, a compost, a factory, etc., or is used as a mixture. By adding and mixing with the above, it is possible to enhance various effects such as deodorization, sterilization, denitrification, dephosphorization, water quality improvement, sludge reduction, and aeration energy saving, which will be described later, in the reaction due to the catalytic effect.

In FIG. 2, the processing tank 21 has already been described with reference to FIG. 1, and resin or glass is used as a binder, and at least a magnetic material and a plurality of kinds of metal oxides such as iron, cobalt and titanium are added to the ferrite system. A plurality of functional ceramic granules obtained by sintering a mixture of materials are mixed and accommodated, raw water is introduced into the treatment tank, and the raw water is passed through and brought into contact with the functional ceramic granules to obtain catalytic water. To generate. The wastewater treatment facility 22 introduces wastewater from livestock industries such as pig farming, wastewater from agricultural settlements, general household wastewater, wastewater for leisure such as golf courses, and other untreated wastewater so that the quality of water meets prescribed standards. It is a facility for water quality improvement and purification treatment, and has, for example, an anaerobic filter bed tank, an aerobic filter bed tank, a sedimentation tank, a sludge concentration storage tank, a disinfection tank, and the like.
The catalytic water generated in the treatment tank 21 or another treatment tank may be added to the anaerobic filter bed tank and the sludge concentration storage tank. This is because the treatment effect of the wastewater treatment facility can be further enhanced. The sodium hypochlorite addition part 23 is for adding and mixing sodium hypochlorite to the raw water introduced into the treatment tank 21, and the catalyst water mixing part 24 is the catalyst water generated by the treatment tank 21 in the untreated wastewater. Is added and mixed. Treated wastewater extraction part 2
5 is for extracting, for example, about 20% as raw water to be introduced into the treatment tank 21 from the treated effluent treated in the effluent treatment facility 22 so as to have a water quality satisfying a predetermined standard. Sodium hypochlorite is added and mixed in the acid soda addition section 23 and introduced into the processing tank 21. In this way, by partially extracting the treated wastewater and refluxing it to generate catalyst water, it is possible to eliminate wasteful use of water and effectively utilize the wastewater. Since the wastewater treatment facility 32 usually has a disinfection tank as described later, when sodium hypochlorite is added and mixed in this disinfection tank, the sodium hypochlorite addition section 23 is omitted. It

FIG. 3 is a diagram showing an embodiment of a method of using catalytic water. 31 is a treatment tank, 32 is a water use facility, and 33 is a water use facility.
Indicates a wastewater treatment facility.

In FIG. 3, the processing tank 31 has already been described with reference to FIG. 1, and resin or glass is used as a binder, and at least a magnetic material and a plurality of kinds of metal oxides such as iron, cobalt and titanium are added to the ferrite system. A plurality of functional ceramic particles formed by sintering a mixture of materials are mixed and accommodated, raw water is introduced into a treatment tank, and the raw water is passed through and contacted with the functional ceramic particles to generate catalytic water. To do. The water use facility 32 is the treatment tank 3
For example, it is a food factory or the like that uses the catalyst water generated in 1. The wastewater treatment facility 33 is a facility that treats the wastewater discharged from the water use facility 32 so that the quality of the water satisfies a predetermined standard. For example, an anaerobic filter bed tank, an aerobic filter bed tank, a sedimentation tank, and sludge concentration It has a storage tank and a disinfection tank. The catalytic water generated in the treatment tank 31 or another treatment tank may be added to the anaerobic filter bed tank and the sludge concentration storage tank. This is because the treatment effect of the wastewater treatment facility can be further enhanced.

FIG. 4 is a diagram showing an example of the structure of the wastewater treatment facility. 41 is a flow rate adjusting tank, 42 is a raw water tank, 43 is an anaerobic filter bed tank, 44 is an aerobic filter bed tank, 45 is a sedimentation tank, Reference numeral 46 indicates a sludge concentration storage tank, and 47 indicates a disinfection tank / discharge tank.

In FIG. 4, the flow rate adjusting tank 41 uses the discharge water from the water use facility 22 shown in FIG. 2 containing the catalyst water and the various discharge water shown in FIG. , For adjusting the flow rate of the raw water tank 42
Is for storing raw water through the flow rate adjusting tank 41. The anaerobic filter bed tank 43 performs anaerobic treatment with anaerobic microorganisms, and the aerobic filter bed / aeration tank 44 performs aerobic treatment and aeration treatment with aerobic microorganisms to oxidize organic matter and solidify carbonization. It is made into powder and then powdered.
The settling tank 45 precipitates the sludge remaining in the water treated by the anaerobic filter bed tank 43 and the aerobic filter bed / aeration tank 44, and the sludge concentration storage tank 46 is the anaerobic filter bed tank 43, The sludge from the aerobic filter bed / aeration tank 44 and the sedimentation tank 45 is concentrated and stored, and if necessary, transferred to a sludge storage tank and carried out. Here, the catalyst water is not limited to the raw water, but the anaerobic filter bed tank 4
3. It may be added to the sludge thickening storage tank 46 as needed. As a result, the decomposition of ammonia can be promoted and the effects of oxidizing, deodorizing, sterilizing, and the like of organic substances can be further enhanced. The surplus water discharged from the sludge concentration storage tank 46 is returned to the anaerobic filter bed tank 43 because the water quality has not been sufficiently improved. The disinfection tank / exhaust tank 47 is for adding sodium hypochlorite to the supernatant water in which sludge has been settled in the settling tank 45, disinfecting it, storing it, and discharging it as treated wastewater.

The wastewater treatment facility is constructed, for example, as described above, and various treatment facilities conventionally used, for example, the Japan Agricultural Village Drainage, which corresponds to the agricultural village drainage business outline described above, is incorporated. JA at the association (JARUS)
RUS type processing facilities are being developed, but these processing facilities can also be adopted. By the way, looking at the JARUS type treatment facility, we combined the anaerobic filter bed and contact aeration in consideration of the type S and type 1 of the system that combines precipitation separation and contact aeration according to the population to be treated and nitrogen removal. Type 2 of the
Type 3 in which a flow rate control tank is installed in front, and a combination of anaerobic filter bed and contact aeration is used. Type 3 in consideration of nitrogen removal and in consideration of nitrogen removal, method 4 in which an anaerobic filter and contact aeration are combined.
Type, type 5 that combines anaerobic filter bed and contact aeration
There are various types such as batch activated sludge type 6, batch activated sludge type 7 with consideration of nitrogen removal, 7G type, continuous inflow intermittent aeration type 8 and 9.

Depending on the wastewater treatment facility, anaerobic filter bed tank 4
3 is not present, or there is no aerobic filter bed / aeration tank 44, or there may be no settling tank 45, but if there is an anaerobic filter bed tank 43 depending on each configuration, then As described above, by adding catalytic water also to the anaerobic filter bed tank 43,
The effect of improving water quality can be enhanced. That is, the present invention is not particularly limited to the configuration of the wastewater treatment facility, it can be applied to various configurations, types of wastewater treatment facility, in short, by adding catalytic water at that time, the treatment effect can be further improved. It can be raised.

As shown in FIG. 2 and FIG. 3, catalytic water of functional ceramics is used for these raw waters, and when sodium hypochlorite NaClO is brought into contact with water H ₂ O, it chemically changes to caustic soda NaOH and pH is changed. Since it is made alkaline, microaerobic microorganisms are generated due to the influence, and aeration and aeration are almost unnecessary. Therefore,
Aeration of one-fourth of normal increases the activity of microorganisms and reduces sludge, resulting in a great energy saving effect. In addition, in the treatment by the aerobic filter bed / aeration tank 44, the organic matter is oxidized and becomes a charcoal substance by utilizing the microorganisms that prefer to live in the presence of the enzyme (hydrolytic enzyme = DO). Can be reduced to an amount of sludge that is discharged from the sludge thickening storage tank after being turned into a carbonized solid and further powdered. Furthermore, the effects of water quality improvement and purification such as deodorization, sterilization, oil decomposition, etc. can be achieved. By mixing the catalyst water of the present invention with grease and other industrial waste oil, the oil-specific mist disappears and oil decomposition is significantly promoted. It is confirmed to do.

Next, the raw water H ₂ O is added to sodium hypochlorite Na.
The reaction by the catalytic action when an aqueous solution containing about ₁ to 3 ppm of ClO or chlorine Cl ₂ passes through and contacts the granules of the functional ceramic will be described.

[0030] [Formula 1] _{NaClO + H 2 O → HClO +} NaOH Cl 2 + H 2 O → HCl + HClO HClO → HCl + O Cl 2 + H 2 O → HClO + H + + Cl - HClO ← → H + + ClO - by the reaction, the sodium hypochlorite NaClO Water H ₂ O
When in contact with hypochlorous acid HClO and caustic soda Na
It changes to OH and becomes alkaline. This reaction is extremely slow and does not easily proceed to the right under normal conditions, but the functional ceramic acts as a catalyst that significantly promotes the action to the right. The same applies to the case of chlorine Cl ₂ . Then, the hypochlorous acid HClO is further decomposed to generate nascent oxygen, and this oxygen exhibits a strong oxidizing action. Therefore, of the decaying odors and excretion odors of living organisms, for example, the unpleasant odor of public toilets is mainly composed of skatole (3 methylindole), but has a -NH- functional group, and thus shows weak basicity [ Chemical formula 2] It reacts with hydrochloric acid like 2C ₉ H ₉ N + HCl → 2C ₉ H ₉ N · HCl to generate skatole hydrochloride.
This amine salt becomes odorless and soluble. Ammonia, which is a component of excreted odor, is hypochlorous acid and [Chemical Formula 3] 2NH ₄ ⁺ + 3HClO → N ₂ + 3H ₂ O + 5H ⁺ +3
Ammonia is decomposed and deodorized by reacting like Cl ⁻ . These are hydrolyzed easily by catalytic action in order to bring water containing sodium hypochlorite into contact with the functional ceramic in the treatment tank, and thus, as shown in [Chemical Formula 1] above, This is because it produces caustic soda.

When ammonia or amine is present in water, it combines with chlorine to produce chloreramine (NH ₂ Cl). When chlorine is injected into ammonia-containing water, the residual chlorine (free chlorine that has not become Cl) gradually increases, but at some point, it begins to decrease sharply, reaches a local minimum, and then increases again. This point is called a discontinuity point, which is the point at which reducing substances such as ammonia have disappeared, and the amount of chlorine added up to this point is called the required chlorine amount. Bonded residual chlorine There is chlorine bonded to ammonia, amine, etc. as a nitrogen compound in the water. Hypochlorous acid is 4HClO → 4
Performs sterilization, deodorization and cyanidation by the reaction of HCl + 40.

Further, hydrogen sulfide is [Chemical formula 4] H ₂ S + NaOH → NaHS + H ₂ O NaHS + NaOH → Na ₂ S + H ₂ O Na ₂ S + 4NaClO → Na ₂ SO ₄ + 4NaC together with caustic soda.
l Na ₂ S + NaClO + H ₂ O → NaCl + NaO
It reacts like H + S and is decomposed and deodorized.

For example, the component of a compound called red hump or red rust deposited inside a long-used water pipe is mainly iron hydroxide Fe (OH) ₃ and calcium carbonate CaC.
O ₃ , magnesium carbonate MgCO ₃ , iron oxide Fe
It is composed of ₂ O ₃ , Fe ₃ O _4, etc. In the water catalyst treatment device of the catalytic water of the functional ceramic, since hypochlorous acid HClO and hydrochloric acid HCl are produced in the catalytic water as described above, [Chemical formula 5] Fe (OH) ₃ + 3HCl → FeCl ₃ + 3H ₂ O CaCO ₃ + 2HCl → CaCl ₂ + H ₂ CO ₃ and Fe (OH) ₃ is soluble FeCl ₃
Then, CaCO ₃ is changed into soluble CaCl ₂ , which dissolves red cobb.

In the wastewater treatment with microorganisms, by utilizing aerobic microorganisms that prefer to inhabit where an enzyme (hydrolytic enzyme = DO) is present, [Chemical Formula 6] (aerobic oxidation) organic matter (C _x H _y O _z ) + O ₂ + aerobic microorganism → CO
₂ + H ₂ O + activity energy of microorganisms (growth of microorganisms) Organic matter (C _x H _y O _z ) + N compound + O ₂ + aerobic microorganism → CO ₂ + H ₂ O + energy (endothermic reaction) and organic matter is oxidized It decomposes and is used for the active energy of microorganisms and the growth of organisms. Therefore, since the organic matter is oxidized to be a carbide, the organic matter becomes a carbonized solid matter, which is further powdered to reduce the amount of sludge carried out from the sludge concentration storage tank.

Next, a concrete example will be described. FIG. 5 is a diagram showing a comparative example of hydrogen sulfide concentration before and after use of catalytic water in a treatment facility, and FIG. 6 is a diagram showing a comparative example of methane gas concentration before and after use of catalytic water in a treatment facility. is there. As the functional ceramic particles, the first particles are 2
5φ sphere, ferrite, magnetic material, iron, molybdenum,
18 kinds of metal oxides including cobalt, titanium, magnesium, aluminum, potassium, zirconium, and silicon are combined, and the second particle is a 15φ sphere, and a ferrite-based magnetic material and iron and manganese, cobalt, titanium, 18 kinds of metal oxides including magnesium, aluminum, potassium, zirconium, and silicon are combined, and the third particle is a sphere of 15φ, and aluminum oxide, zirconia,
Diatomaceous earth and a metal oxide containing barium titanate were combined and sintered, and as a breakdown of the weight of 25 kg, the ratio of the first and second particles to the third particles was 95: 5, the first particles. The ratio of the body to the second granules was 7: 3. In other words, the first granules are about 16.525kg, the second granules are 7.125k.
g, and the third granule was 1.250 kg.

The functional ceramic granules are mixed with raw water containing 1 ppm of sodium hypochlorite so as to pass through the raw water for catalytic treatment to generate catalytic water. , Figure 5 shows the hydrogen sulfide concentration when it is used in the wastewater treatment plant for general household wastewater, and Figure 5 shows the hydrogen sulfide concentration when it is used in the food processing water treatment plant. The following is ▲. On the other hand, the hydrogen sulfide concentration before using the catalyst water is represented by ● in FIG. Methane gas concentration when catalytic water is used in wastewater treatment plants for agricultural village wastewater and general household wastewater,
Figure 6 shows the concentration of methane gas before using catalytic water.
Is. The amount of catalytic water per hour for 1 kg of functional ceramic particles is 0.041 to 0.043 m ³ /
It was h.

Throughout the results of these tests, hydrogen sulfide,
Almost no methane gas is generated, agricultural village drainage,
In the wastewater treatment of general domestic miscellaneous wastewater, odor is reduced to a level where it is hardly felt in one week to 10 days, and the sedimentation rate of activated sludge after aeration is shortened, which is 1/3 of the conventional sludge generation amount. The effects such as the above reduction were recognized. In the industrial water field, by switching the water used in food factories to catalytic water, the functions of existing wastewater treatment facilities have been improved, the quality of the discharged water has been dramatically improved, and sludge residue and sludge have been improved. Was significantly reduced.

Further, in the leisure water field, the use of catalytic water for the water reservoir (fountain) of the golf course eliminated the blue algae and made the water transparent. By using it for watering, it was possible to reduce pesticides by reducing diseases such as dying of grass and wilting and pests.

According to the inspection data so far, the pH is 6.2.
→ 7.5, BOD concentration 160 → 8.3 mg / l, suspended matter 150 → 17 mg / l, total nitrogen 19 → 3.2 m
g / l result, pH 7.1 → 7.6, BOD concentration 36 → 7.0 mg / l, suspended matter 140 → 27 mg /
1 and the total nitrogen content was 17 → 11 mg / l.

When the functional ceramic catalyst water is used, the chlorine odor of the water discharged from the terminal faucet disappears after a few hours, and the red lumps in the pipe are almost removed after 4 months. Therefore, when discharged into the sewer, the offensive odor of the wastewater treatment facility and the sewer pipe disappears. It is considered that this is because the emulsion action is improved and the free residual chlorine is not consumed by the red cob, and a large amount of the free residual chlorine flows into the sewer, which increases the sterilization effect.

The ClO ⁻ produced by the above-mentioned reaction of [Chemical Formula 1] is more active than the dimolecular chlorine Cl ₂ and the hypochlorous acid HClO existing as a gas and has a high sterilizing ability. In fact, a circulating bath attached to the sauna (20 a day
1 dl, 4,000,000 general bacteria and 16 Escherichia coli were detected in (00 people use), but in the water quality test 10 days after using the catalytic water of the functional ceramic, the number of general bacteria was 3,500. , E. coli decreased to 0, and after one month, both general bacteria and E. coli became 0, showing a remarkable effect.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above-described embodiment, the processing system and method using the catalytic water of the functional ceramic have been described.
Introduce the air inlet of the air purifier into the catalyst water to pass the exhaust air, smoke, and air supply as bubbles, or atomize and supply the catalyst water to the exhaust pipe, the smoke exhaust pipe, and the air inlet of the air purifier.
