Field of the Invention The present invention relates to a deodorizing and purifying apparatus and a water catalytic processing apparatus using a functional ceramic for performing deodorization and purification of gas by utilizing the catalytic action of a functional ceramic, and generating and treating catalyst water.

[0002]

2. Description of the Related Art In recent years,
The pollution of the atmosphere, rivers, lakes, and seas by exhaust and drainage has become a major problem as environmental destruction. Among them, considering the pollution of rivers, lakes, marshes and the sea by drainage, there are various types of drainage and various regulations are established. For example, in agricultural settlement drainage, the agricultural settlement drainage project implementation guidelines (April 1983
The Secretary-General of Agriculture, Forestry and Fisheries was enacted on April 4, and its purpose is as follows.

[0003] In recent years, due to changes in the circumstances surrounding agriculture and rural areas, such as the progress of congestion in rural communities, sophistication of lifestyles, and changes in agricultural production styles, the pollution of agricultural wastewater has progressed, and the growth of agricultural crops has suffered. 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 foul odors. For this reason, to maintain the water quality of agricultural drainage, maintain the function of agricultural drainage facilities or improve the rural living environment, and at the same time contribute to the conservation of water quality in public water areas, excrement in agricultural settlements, household wastewater, etc. Sewage, sludge or rainwater treatment facilities.

[0004] In addition to such agricultural settlement wastewater, wastewater from the livestock industry such as swine raising, general household wastewater, wastewater from food factories and semiconductor manufacturing factories and other factories, leisure water from golf courses and the like are included. There is a wide variety of wastewater around the world that needs to be improved to a certain level of water quality. Moreover, these wastewaters have different components to be treated, such as human waste, chemical fertilizers, detergents, and household oils.
There are various purposes and effects for improving water quality, such as deodorization, oil decomposition, and sterilization.

[0005] However, in order to effectively improve the water quality of such various wastewaters, a large-scale and complicated wastewater treatment facility is required for each purpose, and the cost for wastewater treatment is high. Problem.

In addition, facilities such as wastewater treatment, sewage treatment, and sludge treatment, livestock breeding facilities, and meat processing facilities generate a large amount of gas containing hydrogen sulfide gas, ammonia gas, and other malodorous components. A device for deodorizing and purifying air is used. As an apparatus conventionally used for deodorization, for example, there is an apparatus that absorbs and removes 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 alkali washing, if caustic soda is used as the alkali washing solution, the carbon dioxide absorbed in the washing solution reacts with the caustic soda to change into sodium carbonate or sodium bicarbonate, thereby increasing the efficiency (removal). Rate) decreases. Therefore, in order to maintain the desired efficiency, it is necessary to supplement caustic soda, and it is difficult to maintain sufficient hydrogen sulfide removal efficiency. In addition, as a method for removing a trace amount of sulfur compounds that cannot be completely removed by alkali washing, a combination of an activated carbon adsorption method, an ozone deodorization catalyst method, and the like is employed.

Therefore, in order to efficiently remove the sulfur compound from the gas containing a periodic component 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 a zinc salt as an alkaline cleaning solution, and the sulfur compound is contained in the sulfur compound. Has been proposed for separating and removing as zinc sulfide (for example, Japanese Patent No. 2731124). According to this method, it is necessary to maintain the content of the zinc salt in the aqueous sodium carbonate solution at an equivalent ratio of at least 3 times the zinc sulfide accumulated as a suspension and a precipitate in the aqueous solution, Special considerations are needed for adjusting and maintaining the zinc salt content.

[0009]

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a view showing an embodiment of a deodorizing purification and water catalyst treatment apparatus using a functional ceramic according to the present invention, wherein 1 is a treatment tank, 2 is a functional ceramic granule, 3 is a basket, and 4 is an air supply. 5, an exhaust unit, 6 is a water supply unit, 7 is a drainage unit, 8 to 11 are valves, 12 is an exhaust fan, 13 is catalyst water, and 14 is a watering nozzle.

In FIG. 1, the treatment tank 1 has an exhaust unit 5 and an exhaust fan 12 near the ceiling, a water supply unit 6 and a water spray nozzle 14 below, and an air supply unit 4 and a drainage unit 7 near the bottom. And a plurality of cages 3 in which a plurality of functional ceramic particles 2 are mixed and stored. The water supply unit 6 drip sodium hypochlorite (NaClO) as a dropping agent into the raw water with the valve 10, supplies an aqueous solution of sodium hypochlorite having a concentration of about 1 to 3 ppm to the spray nozzle 14, and supplies the treatment tank 1 from above. It is introduced in. Drainage part 7
Is for taking out the catalyst water 13 which is showered from the watering nozzle 14 and generated by the catalysis when passing through and contacting the plurality of functional ceramic particles 2. By removing the catalyst water from a predetermined height level from the bottom, the catalyst water is stored in the treatment tank 1 up to the predetermined height level.
The height level may be, for example, up to a half of the number of stages of the cage 3, or the number of stages of the cage 3 in the catalyst water 13 and the number of stages of the cage 3 above the water surface of the catalyst water 13 may be appropriately set. Even if it changes, the height level may be adjusted according to the number of stages of the basket 3. The air supply section 4 supplies, for example, a gas such as an odorous component-containing gas, other gas, or air through a valve 8 and introduces the catalyst water stored in the processing tank 1 from the vicinity of the bottom. 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 granules 2 and the catalyst water. The exhaust fan 12 feeds the air into the exhaust unit 5.

The functional ceramic particles 2 are obtained by sintering a resin or glass as a binder and combining a ferrite with at least a magnetic material and a plurality of metal oxides such as iron, cobalt and titanium. Is the first
A plurality of types of granules having different component concentrations, including the granules of the first, second and third granules, are mixed and accommodated in the basket 3 and stacked in several stages (four stages in the illustrated example). To be replaceable. The first grain is a ferrite-based magnetic material,
Iron, molybdenum, cobalt, titanium, magnesium, aluminum, potassium, zirconium, sintering a combination of metal oxides of silicon, the second particles,
Ferrite is obtained by sintering a combination of at least a magnetic substance and iron and manganese, cobalt, titanium, magnesium, aluminum, potassium, zirconium, and a metal oxide of silicon. It is obtained by sintering a combination of zirconia, diatomaceous earth, and barium titanate metal oxide.

These particles can improve the efficiency of ion reaction by controlling the concentration of the components and changing the atomic percentage. The first particles have a remarkable effect particularly on the sterilization and deodorization effects. It was confirmed that the second granules had a remarkable effect on oil decomposition and sterilization, and the third granules had a remarkable effect on oil decomposition. Also, the first
When the first granule and the second granule are mixed, the first granule and the second granule react with each other due to the different component concentrations, and the efficiency of ion generation is improved. It has also been demonstrated that by adding a small amount of the third granules, the oil cracking proceeds more. In addition, the third granules have a strong coagulating action, form molecules in a floc shape, and have an action of making oil components hydrophilic and lipophilic. Therefore, many effects of increasing the sedimentation speed of sludge have been confirmed at wastewater treatment plants. In other words, since the function of organic decomposition is improved, it contributes to the improvement of water quality,
It removes the oxidized odor of the oil, which leads to a better deodorizing effect. This is based on many years of experience in functional ceramics research and repeated tests. Based on this experience, the ratio standard of each granule is determined by applying it to deodorization, water quality improvement, and the like.

Therefore, by controlling the component concentration and changing the mixing ratio of the first to third granules, it is possible to enhance the effect according to the processing purpose. For example, ammonia, hydrogen sulfide, nitrogen, phosphorus, and the like are large in wastewater from the livestock industry such as pig farming, agricultural settlement wastewater, and general household wastewater, and a deodorizing effect is particularly required. Also, factory wastewater including wastewater from food factories and canteens and restaurants contains a large amount of oil, nitrogen, phosphorus, etc., and is particularly required to have an oil decomposition effect. The mixing ratio of the first to third granules is set according to each of these requirements.

In the deodorizing purification and water catalyst treatment apparatus using the functional ceramic according to the present invention, the aqueous sodium hypochlorite solution is showered by the watering nozzle 14 and sequentially passed from the upper functional ceramic particles 2 to contact therewith. It is stored further downward and is brought into contact with the lower functional ceramic particles 2 through the drainage section 7 until it reaches the drainage section 7 to perform catalytic water treatment to generate catalytic water. It is taken out from the drainage section 7 through the valve 11 and is added to sewage, wastewater, and sludge to be used as catalyst water for improving the treatment effect or improving the quality of commercial water and the like. On the other hand, ammonia, dioxin, carbon dioxide (CO ₂ ), and hydrogen sulfide in the gas are removed by the catalyst water generated by passing the aqueous sodium hypochlorite solution into contact with the functional ceramic particles 2 as described above. Deodorization and purification can be performed.

In the apparatus having the above-described structure, the aqueous solution of sodium hypochlorite flows from the upper part to the lower part in the treatment tank 1 and passes through the functional ceramic particles 2 arranged in multiple stages to produce catalytic water. At the same time as it is taken out, the gas flows upward from the completely opposite direction from the bottom,
In the stored catalyst water 13, the gas becomes bubbles and rises between the functional ceramic particles 2 to oscillate and come into contact with each other to remove dirt attached to the functional ceramic particles 2 and perform cleaning. It can be carried out. Therefore, the particles in the catalyst water 13 and the particles above the catalyst water 13 can be maintained in the same state by occasionally replacing the functional ceramic particles 2 between the upper stage and the lower stage.

The catalyst water taken out from the drainage section 7 is used as water in an agricultural settlement drainage treatment plant, a treatment plant in the livestock industry, a breeding farm, a meat center, a compost, a factory, or the like, or used by mixing. By adding and mixing with water, various effects such as deodorization, sterilization, denitrification, dephosphorization, water quality improvement, sludge reduction, and aeration energy saving, which will be described later, can be enhanced by a reaction using a catalytic effect.

Sodium hypochlorite is added and mixed in the acid soda adding section 23 and introduced into the treatment tank 21. By thus extracting and refluxing a part of the treated wastewater to generate the catalyst water, it is possible to effectively use the wastewater without using waste water. 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.

Here, the catalyst water is used not only in the raw water but also in the anaerobic filter bed tank 4.
3. The sludge concentration storage tank 46 may be appropriately added as needed. This can promote the decomposition of ammonia and further enhance the effects of oxidizing, deodorizing, and sterilizing organic substances. Further, 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 disinfecting tank / discharging tank 47 is for disinfecting and adding sodium hypochlorite to the supernatant water from which the sludge has been settled in the sedimentation tank 45, and storing and discharging the treated wastewater.

The wastewater treatment facility is constructed, for example, as described above, and various treatment facilities conventionally used, for example, Japanese agricultural settlement drainage corporations corresponding to the agricultural settlement drainage business outline described above. JA at the Association (JARUS)
RUS type processing facilities are being developed, but these processing facilities can also be adopted. By the way, even if you look at the JARUS type treatment facility, according to the population to be treated, etc., the anaerobic filter bed and the contact aeration are combined in consideration of the nitrogen removal and the S type, which combines sedimentation and contact aeration.

As shown in FIGS. 2 and 3, deodorizing purification using the functional ceramic according to the present invention and using catalyst water generated by a water catalyst treatment apparatus as shown in FIGS. Is chemically changed to caustic soda NaOH when brought into contact with water H ₂ O to make the pH alkaline, so that microaerobic microorganisms are generated due to the effect, and aeration aeration is almost unnecessary. Therefore, the activity of the microorganisms is increased by the aeration of 1/4 of usual, and the sludge is reduced, so that a great energy saving effect can be obtained. Moreover, in the treatment in the aerobic filter bed tank / aeration tank 44, the organic matter is oxidized to carbonized by utilizing microorganisms that preferentially inhabit where the enzyme (acid enzyme = DO) is present. Can be turned into carbonized solids and further powdered to reduce the amount of sludge carried out of the sludge concentration storage tank. Furthermore, the effects of water quality improvement and purification, such as deodorization, sterilization, and oil decomposition, can also be improved. By mixing the catalyst water of the present invention with grease or other factory waste oil, the oil-specific muddy disappears, and oil decomposition remarkably accelerates.

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

When contacted with sodium hypochlorite and sodium hydroxide
Chemically changes to OH and becomes alkaline. Although this reaction is extremely slow and does not readily proceed to the right under normal conditions, the functional ceramic acts as a catalyst that significantly enhances the rightward action. The same applies to the case of chlorine Cl ₂ . Then, the hypochlorite HClO is further decomposed to generate nascent oxygen, and this oxygen exhibits a strong oxidizing action. Therefore, among the putrefaction odors and excretion odors of organisms, for example, the unpleasant odor of public toilets is mainly composed of skatole (3-methylindole), but has a weak basicity because it has a functional group of -NH-.

Embedded image 2NH ₄ ⁺ + 3HClO → N ₂ + 3H ₂ O + 5
Ammonia is decomposed and deodorized by reacting like H ⁺ + 3Cl ⁻ . These are easily hydrolyzed by catalysis because the water to which sodium hypochlorite is added passes through the treatment tank and comes into contact with the functional ceramic in the treatment tank, and as shown in the above [Chemical Formula 1], This is because it produces caustic soda.

When ammonia or amine is present in water, it binds to chlorine to produce chloreramine (NH ₂ Cl). When chlorine is injected into the ammonia-containing water, the residual chlorine (free chlorine which is not Cl) gradually increases, but at a certain point, starts to decrease suddenly, reaches a minimum point, and then increases again. This point is called a discontinuous point, and is a point at which a reducing substance such as ammonia has disappeared, and the amount of chlorine added so far is called a chlorine demand. As a nitrogen compound, chlorine bonded to ammonia, amine, or the like is present in the combined residual chlorine water. Hypochlorous acid is 4HClO → 4
Sterilization, deodorization and cyanidation are performed by the reaction of HCl + 4O.

Further, hydrogen sulfide is added together with caustic soda.

For this reason, the organic matter is oxidized to be a carbide, so that the organic matter becomes a carbonized solid, and the amount of sludge which is further pulverized and carried out of the sludge concentration storage tank can be reduced.

Next, a specific embodiment will be described. FIG. 5 is a diagram showing a comparative example of the concentration of hydrogen sulfide before and after use of catalytic water in a water catalyst treatment apparatus in a treatment facility, and FIG. 6 is a diagram showing a deodorization purification in the treatment facility according to the present invention. It is a figure which shows the comparative example of the methane gas concentration before and after use of the catalyst water of the water catalyst treatment apparatus. As a functional ceramic particle, the first particle is a sphere having a diameter of 25φ, and a ferrite-based magnetic material, iron, molybdenum, cobalt, titanium, magnesium, aluminum, potassium, zirconium,
The second particle is a sphere having a diameter of 15φ, and includes a ferrite-based magnetic material and iron and manganese, cobalt, titanium, magnesium, aluminum, potassium, zirconium, and silicon. Combining different types of metal oxides, the third particle is a 15φ sphere,
Combining and sintering metal oxides including aluminum oxide, zirconia, diatomaceous earth, and barium titanate, 25 kg
The ratio of the first and second granules to the third granules was 95: 5, and the ratio of the first and second granules was 7: 3. That is, the first granular material is approximately 16.525.
kg, the second granule is 7.125 kg, and the third granule is 1.125 kg.
The weight was 250 kg.

By contacting raw water obtained by adding and mixing 1 ppm of sodium hypochlorite to the functional ceramic particles, water treatment utilizing a catalytic action is carried out to generate catalytic water, and this catalytic water is drained from an agricultural settlement. Figure 5 shows the concentration of hydrogen sulfide when used in a general domestic household wastewater treatment plant. Figure 5 shows the concentration of hydrogen sulfide when used in a food processing water treatment plant. The following is ▲. On the other hand, the concentration of hydrogen sulfide before using the catalyst water is indicated by ● in FIG. Methane gas concentration when catalytic water is used in wastewater treatment plants for agricultural settlement drainage and general household wastewater,
FIG. 6 shows the methane gas concentration before using the catalyst water.
It is. The amount of catalyst water per hour per 1 kg of functional ceramic particles is 0.041 to 0.043 m ³ /
h.

Through the results of these tests, hydrogen sulfide,
Almost no methane gas is generated, agricultural village drainage,
In the wastewater treatment of general household household wastewater, the odor is reduced to such an extent that almost no odor is felt in one week to 10 days, and the sedimentation speed of activated sludge after aeration is shortened, which is one third of the conventional sludge generation amount. The effects such as the above reduction were recognized. In the industrial water field, the water used in food factories has been switched to catalytic water, which has improved the functions of existing wastewater treatment facilities, significantly improved the quality of discharged water, and further improved sludge residue and sludge. Was significantly reduced.

In the leisure water field, the use of catalytic water in the reservoir (fountain pond) of the golf course eliminated the blue algae and made the water transparent. By using it for watering, diseases and pests such as wilt and wilt were reduced and pesticide-free.

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

When the catalyst water generated by the deodorizing purification and water catalyst treatment apparatus using the functional ceramic according to the present invention is used, the chlorine odor coming out of the terminal faucet after several hours is eliminated, and the red bump in the pipe is eliminated. Is almost eliminated after 4 months. Therefore, when discharged into the sewer, the odor of the wastewater treatment facility and the sewer is eliminated. This is considered to be due to the improvement of the emulsion action and the fact that the free residual chlorine is not consumed by the red knot and the free residual chlorine flows to the sewer correspondingly, thereby increasing the sterilizing effect.

[0047] ClO produced by the reaction of that shown earlier [Chemical 1] ^- is compared to bimolecular chlorine Cl ₂ and hypochlorite HClO present as a gas, sterilizing ability because it is active high. Actually, the circulation bath attached to the sauna (20 per day)
1 dl, 4,000,000 common bacteria and 16 Escherichia coli were detected in the case of "00 person use", but the catalyst water generated by the deodorization purification and water catalyst treatment device using the functional ceramic according to the present invention was used. In the water test 10 days later,
The number of general bacteria was reduced to 3,500, and the number of Escherichia coli was reduced to 0. After one month, both the number of general bacteria and Escherichia coli were reduced to 0, showing a remarkable effect.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are possible. For example, in the above-described embodiment, the deodorization purification and water catalyst treatment apparatus and the water treatment system and method using the catalytic water of the functional ceramic have been described. However, the exhaust pipe, the smoke exhaust pipe, and the air introducing portion of the air purifier are provided with the catalytic water. The exhaust gas, smoke exhaust, and air supply are introduced by introducing air into the exhaust, smoke exhaust, and air supply as bubbles, and the catalyst water is atomized and supplied to the exhaust pipe, smoke exhaust pipe, and air inlet of the air purifier. It may be configured to be used for purification of water, or may be used as a device for simply generating catalyst water by feeding ordinary air instead of a gas containing malodorous components into a deodorization purification and water catalyst treatment device. Although the level of the catalyst water stored in the tank is set to an intermediate level, it may be raised to the level above the nozzle. Further, by circulating a part or all of the catalyst water, raw water and sodium hypochlorite or chlorine may be appropriately replenished according to the consumption thereof, and may be used as a gas deodorizing and purifying apparatus. A part thereof may be taken out as catalyst water and used.

In addition, for example, by using catalytic water for body washing, truck cleaning, deodorizing, disinfection in the yard, cleaning and discharging of filth, and clean room for the arrival of livestock,
The effect of improving and purifying the water quality of these wastewaters can be enhanced. Further, the catalyst water according to the present invention is used for improving n-hexane of a grease trap (oil / water separation tank), preventing red rust and red water between water supplies, eliminating silica in a cooling tower, improving water quality, improving condenser cooling effect, saving energy, and cleaning a boiler tube.
