Therefore, if the electrolysis is not continued for a long time, the entire target water cannot be uniformly and sufficiently disinfected. Further, a residual chlorine diffusing device is required to diffuse the residual chlorine throughout. Moreover, since the amount of target water is always large, there is a drawback that residual chlorine is often redissolved. In view of the problems of the conventional electrolytic disinfection, the present invention can select target water and perform electrolysis,
It is provided for the purpose of effectively utilizing the oxygen gas generated during the electrolysis and not being restricted by the place of installation.

As disclosed in Japanese Unexamined Patent Publication No. 87, a technique relating to an underwater immersion type electrolytic disinfecting device that electrolyzes salt contained in water to additionally disinfect water to be disinfected has been developed and proposed. This electrolytic sterilizer is equipped with a pair of electrodes in the main body of the sterilizer, which is immersed in the water to be disinfected to electrolyze the salt contained in the water to be disinfected to remove sodium hypochlorite from the chlorine ions contained. The generated water is used to disinfect the water to be disinfected with this sodium hypochlorite.

ができないという欠点がある。However, this electrolytic disinfection device is simply put in an arbitrary position in the water to be disinfected in a water tank and immersed therein.
Since it only electrolyzes the salt content in the water to be disinfected to generate sodium hypochlorite, it is not possible to disinfect the entire water to be disinfected uniformly unless electrolysis is continued for a long time. There is.

Furthermore, because it is an immersion type in which the electrolytic disinfectant is immersed in the water to be disinfected in the water storage tank, it is possible to check the electrolytic state or maintain the electrolytic disinfectant itself.
There is also a drawback that inspection and cleaning are very troublesome.

的に処理することができる。Moreover, since a part of the stored water 6 in the water storage tank 1 is pumped up by the pump 7 and used as the water to be disinfected,
The stored water 6 can be selectively disinfected and the accumulated water can be purified. In particular, by selecting the pumping point and the returning point of the stored water 6, the stored water 6 in the water storage tank 1 can be efficiently treated.

なり、汚染を招く恐れがある。When the inflowing water is stopped and the stored water 6 remains in the water tank 1, if the electrolysis is continued for a long time, the residual salt in the stored water 6 will be consumed. As the exhaust gas exhausts, its concentration gradually decreases, and finally sodium hypochlorite cannot be produced. For this reason, if the stored water 6 in the water storage tank 1 is left with the disinfection stopped, the disinfecting power of the stored water 6 will rapidly decrease, and the water quality will deteriorate due to the inclusion of pathogenic bacteria, etc., leading to pollution. There is a fear.

て、貯水槽1 内の貯留水6 を全体に亘って消毒する。Therefore, even after the salt content of the stored water 6 in the water storage tank 1 is exhausted and the production of sodium hypochlorite becomes impossible,
The voltage is continuously applied to the electrodes 22 and 23 to switch the electrolysis of salt to the electrolysis of the water to be disinfected to generate oxygen and hydrogen by the electrolysis of the water to be disinfected. Then, while disinfecting the water to be disinfected (oxidative disinfection by contact oxidation) with the oxygen generated during this electrolysis, the water to be disinfected containing a large amount of oxygen after electrolysis is returned to the stored water 6 in the water tank 1. , Disinfect the stored water 6 in the water storage tank 1 all over.

して使用した場合にも問題はない。Of the oxygen generated during electrolysis, the oxygen atoms in the nascent stage have a particularly strong oxidizing power, and the water to be disinfected can be instantaneously and directly oxidatively sterilized. Therefore, even if the stored water 6 with a reduced residual chlorine concentration is stored in the water storage tank 1 for a long time while the inflow water is stopped, the oxidative disinfection action of oxygen generated during electrolysis causes the propagation of pathogenic bacteria. Since the deterioration of water quality can be prevented by preventing or suppressing the above, there is no problem even when the stored water 6 in the water storage tank 1 is used as drinking water thereafter.

移動する。The oxygen generated by electrolysis diffuses into the atmosphere while bubbling in water and disappears if it is left open to the atmosphere, but since the water to be disinfected is electrolyzed in the closed container 12. While bubbling in the water to be disinfected to disinfect the water to be disinfected, it moves together with the water to be disinfected in the closed container 12.

て、更に生命体に有効な水にすることができる。For this reason, the water to be disinfected can be sufficiently disinfected by oxygen, and a large amount of oxygen is dissolved in the water to be disinfected to increase the dissolved oxygen concentration of the water to be disinfected, which is effective for the living organisms. It is possible to improve water quality by transferring it to something.
Moreover, the electrolysis causes water particles of the water to be disinfected into fine particles, and can be made into water that is more effective for living organisms.

自身の劣化、損耗を防止することができる。At the time of electrolysis, a DC voltage is applied between the electrodes 22 and 23, and ON / OFF control is performed by a signal from the control means 55. That is, if there is an ON signal from the control means 55, a large voltage is supplied from the large-capacity power supply section 53 to the electrodes 22 and 23 to flow a large current.
A small voltage is supplied between 2 and 23 to flow a minute current. Therefore, it is possible to prevent wasteful consumption of electric power, and at the same time, the electrodes 22, 23
It is possible to prevent deterioration and wear of itself.

により容易に点検できる。In addition, when it is turned on, the phase inversion section 52 operates by the inversion signal from the control means 55 and intermittently inverts the phase of the voltage applied to the electrodes 22 and 23. Therefore, the scale of the hardness component adhered to the cathode side is scaled. Can be electrically eluted, and the initial performance can be maintained while the maintenance is reduced. Hydrogen and oxygen are generated in the electrolysis chamber 15 during electrolysis of the water to be disinfected, and especially oxygen can be used to improve the water quality, but the state of bubbling of oxygen and the status of the electrodes 22 and 23 at this time can be seen through the inspection window 44. For example, it can be easily visually inspected even from the outside of the closed container 12.
