Also, it maintains a substantially constant water pressure regardless of the height. However, since there is a water tank, the clean water will temporarily stay in the water tank. After clean water, clean water is injected with chlorine, sodium hypochlorite, etc. so that the residual chlorine concentration is maintained at a constant level in the water supply pipe of the supply destination to prevent the propagation of various bacteria.

In addition, foreign matter may be mixed into the storage tank or algae may be generated, resulting in deterioration of water quality. Therefore, the airtightness of the water storage tank has been improved, the number of maintenance work of the water storage tank has been increased, and chlorine-based chemicals such as hypochlorous acid have been added. The increase in maintenance work does not completely solve the problem, and the addition of a large amount of chemicals to the tap water sometimes results in an excess of available chlorine. The above is not preferable either.

題点があった。As a method for preventing these problems, Japanese Patent Laid-Open No. 6-332
Japanese Patent No. 80 discloses a method of disinfecting drinking water by electrolysis. This method consists of placing electrodes with at least one coating selected from platinum and titanium, tantalum, zirconium, niobium, and tin so that adjacent electrodes have different polarities, placing the device in water, and periodically The electrolysis is performed while reversing the polarity, and disinfection is performed according to the generated substance. However, since it is a method of directly electrolyzing tap water or the like, it cannot be energized at a sufficient current density because of the low electric conductivity of water. As a result, the amount of bubbles generated by electrolysis is small even when using a large-scale electrolysis device, and because the generated bubbles cannot stir the liquid, a separate water circulation mechanism is required to disinfect the water in the storage tank. There were problems such as.

The tubular body 13 to which the electrolysis unit 1 is attached is provided in the clean water 15 in the water tank 14. Conductive connection device 8 energizes device 1
It is connected to 6 and the electrolytic current is supplied. The electrolysis unit 1 is operated by an energizing device so as to invert the current to prevent the scale from depositing on the electrodes. Then, as the bubbles 17 generated by electrolysis rise, the ascending current generated inside the tubular body causes the tubular body to flow into the tubular body from the lower portion and to flow from the upper portion into the water tank. As a result, the aquarium water is treated by hypochlorite, ozone, etc. generated while circulating in the tubular body due to the upward flow, and the aquarium water as a whole is agitated.

極めて小さい。In the electrolysis unit of the present invention, the anode and the cathode are provided in close contact with each other on both sides of the cation exchange membrane, so that when the electrodes are energized, the cation exchange membrane acts as a solid electrolyte. As a result, electricity can be applied even when tap water having low conductivity is used. For example, when Nafion 115 or 117 manufactured by DuPont is used as the cation exchange membrane, the resistance is 2Ω or less per 1 cm 2 . 10A /
When energized at a current density of dm 2, the ohmic loss due to the electrolyte is about 0.2 V, which is extremely small compared to the ohmic loss at 10 A / dm 2 in the water electrolysis of ordinary tap water, which is 10 to 20 V.

Since it is possible to increase the size, it is possible to downsize the device.

によっても変化する。For the anode and the cathode, an electrode catalyst containing platinum or iridium oxide, which has been conventionally used for water electrolysis, can be used. Further, in order to adhere the anode and the cathode to the cation exchange membrane, a method in which an electrode obtained by firing an electrocatalyst on the surface of a fine titanium porous body by a pyrolysis method is prepared and then brought into contact with the surface of the cation exchange membrane . Alternatively, one in which platinum is directly electrolessly deposited on the surface of the cation-exchange membrane, one in which platinum or another electrode substance is supported on carbon and which is joined together with carbon by a hot press using a fluororesin as a binder. But good. When platinum is used as the electrode catalyst, ozone is generated in addition to the generation of hypochlorous acid by the oxidation of chlorine ions contained in the tap water. This is remarkable as the current density increases. Further, with iridium oxide, the production efficiency of hypochlorous acid is increased and the production of ozone is reduced. The generation efficiency also changes depending on the chlorine ion concentration in the liquid and the electrolysis current density.

In addition, in the disinfection device of the present invention, it is possible to expect the disinfection effect of the produced substance such as hypochlorite and the oxidative decomposition of the contained substance by direct electrolysis.

The electrolysis unit of the present invention can be energized at a current density of 1 to 50 A / dm 2 . When electrolysis is performed on aquarium water that has an effective chlorine concentration of zero, in a steady state,
The current efficiency of hypochlorite is 0.1 to 3%, and the balance is oxygen generation or, at times, some ozone added thereto. Also, since the contained chlorine ion concentration is low, the effective chlorine concentration does not exceed a few ppm. The same applies to the generation of ozone. If the current density is 30 A / dm 2 or less, the current efficiency is 1% or less.

For example, when operating at 50 A / dm 2 , the generated bubbles are
It can rise at several cm / sec, and an ascending rate of 0.5 cm / sec can be obtained at the electrode surface. Furthermore, the disinfection device of the present invention,
Even water having a low conductivity, such as tap water, can be electrolyzed with a large current density, so that a large effect can be obtained even in a device having a small electrode area.

することも可能である。Further, in the disinfecting apparatus of the present invention, it is possible to prevent the scale from being deposited on the electrodes and the electrolysis being disabled by reversing the current supplied to the electrolysis unit. In the disinfecting apparatus of the present invention, an electrolysis unit is installed in water in a water tank for electrolysis, so that a mixed gas of hydrogen and oxygen generated from the electrolysis unit may accumulate in the upper part of the water tank. Therefore, in the case of such a water tank, it is preferable to ventilate the inside of the water tank or provide a combustion catalyst of hydrogen and oxygen to prevent the accumulation of explosive gas in the upper part of the water tank. The disinfecting apparatus of the present invention is suitable for disinfecting aquarium water in an apartment house or a building, but can also be applied when high-quality water similar to tap water such as a swimming pool is used. .

The water is disinfected by reactivating the active chlorine into effective chlorine, and a small amount of ozone also decomposes organic substances contained in the aquarium water and decomposes algae that cause odors, like active chlorine. Since it can also be performed together, it will be supplied as water of higher quality than the tap water taken into the aquarium.
