Raw water introduced from the water supply unit 5 is removed from the functional ceramic contained in the cage 2. By bringing the particles into contact with the granules 2, water treatment utilizing a catalytic action is performed to generate catalytic water, and the catalytic water is extracted from the catalytic water extracting section 7. The air supply unit 6
An exhaust unit 8 is provided at the bottom of the catalyst tank 1 to supply cleaning air for the functional ceramic particles 2, and the exhaust unit 8 is provided at the ceiling of the catalyst tank 1 to exhaust the cleaning air. is there. The valves 11 to 14 include a water supply unit 5, an air supply unit 6,
It controls the flow of the catalyst water extracting section 7 and the exhaust section 8.

In the water catalyst device having the above-described structure, raw water is introduced into the catalyst tank 1 from the water supply unit 5 through the valve 11 so that the raw water passes through the functional ceramic particles 2 arranged in the catalyst tank 1 in multiple stages and comes into contact therewith. At the same time as the catalyst water is generated and taken out from the catalyst water take-out part 7 through the valve 13, the cleaning air is introduced from the air supply part 6 into the catalyst tank 1 through the valve 12, thereby forming bubbles and particles of the functional ceramics. The body 2 is swung up and brought into contact with each other to remove dirt attached to the functional ceramic particles 2 and perform cleaning. The catalyst water taken out from the catalyst water take-out unit 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 factory, or used in addition to and mixed with water. By mixing and using, deodorization, sterilization, denitrification, dephosphorization, water quality improvement, sludge reduction, etc.
Various effects such as energy saving for aeration can be enhanced.

The functional ceramic particles 2 are obtained by mixing a plurality of types of particles having different component concentrations. The first particles are composed of at least a magnetic substance, iron, molybdenum, cobalt, titanium, magnesium and a ferrite. ,aluminum,
Potassium, zirconium, sintering a combination of metal oxides of silicon, the second particles, ferrite-based at least a magnetic substance and iron and manganese, cobalt, titanium, magnesium, aluminum, potassium, zirconium, The third particle is obtained by sintering a combination of metal oxides of silicon, and the third particle is formed by sintering a combination of metal oxides of at least aluminum oxide, zirconia, diatomaceous earth, and barium titanate.

These particles can improve the efficiency of ion reaction by controlling the component concentration and changing the atomic percentage. The first particles have a remarkable effect on sterilization and deodorization. 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 empirical value, the ratio standard of each granule is determined by applying 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 purpose of processing.

Therefore, in the case of tap water to which chlorine of about 1 to 3 ppm has already been added and mixed, it can be used as raw water as it is. When this raw water is brought into contact with the functional ceramics, a remarkable deodorizing effect can be obtained from the catalytic reaction as described later.

Ammonia is decomposed and deodorized by reacting like H ⁺ + 3Cl ⁻ . These are caused by catalytic action to bring the chlorine-added water into contact with the functional ceramics in the catalyst tank.
This is because molecular chlorine (Cl ₂ ) is easily hydrolyzed to generate hydrochloric acid and hypochlorous acid as shown in the above [Chemical Formula 1].

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. The free chlorine present in the waste water is the total of Cl ₂ , HClO, and ClO, and the effective free chlorine is the total of HClO and ClO, and is combined with ammonia, amines, etc. as nitrogen compounds in the combined residual chlorine water. There is chlorine present. Hypochlorous acid is 4HCl

The ratio of the particles to the second particles was 7: 3. That is, the first granules are about 16.525 kg, and the second granules are 7.125 k.
g, the third granules were 1.250 kg.

The functional ceramic particles are contacted with raw water mixed with 1 ppm of chlorine by passing through the raw water to perform catalytic water treatment to generate catalytic water. The catalytic water is discharged into agricultural settlements, Figure 5 shows the concentration of hydrogen sulfide when used in a wastewater treatment plant for gray water.

FIG. 6 shows the methane gas concentration when catalytic water was used in a wastewater treatment plant for agricultural settlement drainage and general household wastewater, and the methane gas concentration before using catalytic water. The amount of catalyst water per hour per 1 kg of the functional ceramic particles was 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.

You. 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.

[0043] ClO produced by the reaction of that shown earlier [Formula 4] ^- 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)
