In general, a method has been adopted in which a disinfectant is directly injected into water to be disinfected and disinfected. However, this requires replenishment of the disinfecting solution at all times, and has problems in operation and maintenance of the injection device. Further, if the injection amount of the disinfecting solution is incorrect, there is a problem of carcinogenicity due to excessive disinfection, a problem of poor disinfection due to insufficient injection, and a problem of increasing running cost.

As disclosed in Japanese Patent Publication No. 87, a technique relating to an underwater immersion-type electrolytic disinfection apparatus that electrolyzes salt contained in water and additionally disinfects water to be disinfected has been developed and proposed. This electrolytic disinfection device is equipped with a pair of electrodes in the disinfector body, immersed it in the water to be disinfected, electrolyzes the salts contained in the water for disinfection, and converts sodium hypochlorite from the contained chlorine ions. The water to be disinfected is generated and disinfected by this sodium hypochlorite.

がある。This electrolytic disinfection device is
Since the salt contained in tap water etc. can be used directly, there is no need to inject or add a disinfectant solution, which has the advantage of eliminating excessive disinfection and other problems.
There are advantages such as running cost reduction as well as labor saving. However, since this electrolytic disinfection device is simply put in and immersed in an arbitrary location in the water to be disinfected in the water tank, the salt contained in the water to be disinfected is electrolyzed to generate sodium hypochlorite. If the electrolysis is not continued for a long time, there is a drawback that the water to be disinfected cannot be uniformly disinfected over the entirety.

To diffuse quickly throughout the target water, a separate chlorine diffusion device is required. In addition, this electrolytic disinfection device has a disadvantage that the amount of water to be subjected to electrolytic disinfection is very large, and thus residual chlorine is often re-decomposed. Further, since the electrolytic disinfecting device is of the immersion type in which the electrolytic disinfecting device is immersed in the water to be disinfected in the water storage tank, there is a disadvantage that it is very troublesome to check the state of electrolysis or to maintain, check, and clean the electrolytic disinfecting device itself.

安定性が良好である。In addition, since a part of the stored water 6 in the water storage tank 1 is pumped up by the water pump 7 through the water pumping pipe 8 and used as the water to be disinfected, the stored water 6 can be selectively disinfected. Purification of accumulated water is possible. In addition, since the pumping port of the pumping pipe 8 and the return port of the return pipe 11 are separated from each other in the water storage tank 1, the object to be disinfected after the disinfection is returned from the return pipe 11 to the storage water 6 of the storage tank 1. Water is not immediately pumped up by the pump 7 through the water pipe 8. Pumping pipe 8
Since the pumping port at the lower end is located near the bottom of the water storage tank 1 and the water pump 7 is provided on the water pumping port 8 side, the stored water 6 near the bottom of the water storage tank 1 can be pumped up as water to be disinfected. At the same time, the stability of the pump 8 and the pump 7 in the storage water 6 is good.

亘って消毒する。In the state where the inflow water is stopped and the stored water 6 remains in the water storage tank 1, if the electrolysis is continued for a long time, the residual salt in the stored water 6 is consumed. At the end, the concentration gradually decreases, and eventually the production of sodium hypochlorite becomes impossible. Therefore, if the stored water 6 in the water storage tank 1 is left in a state where the disinfection is stopped, the disinfecting power of the stored water 6 is rapidly reduced, and water quality is deteriorated due to contamination with pathogenic bacteria and the like, resulting in pollution. There is fear. Therefore, even after the storage water 6 in the storage tank 1 has lost the salt content and the generation of sodium hypochlorite has become impossible, the application of the voltage to the electrodes 22 and 23 is continued, and the disinfection target from the salt electrolysis is continued. Switch to electrolysis of water itself, and generate oxygen and hydrogen by electrolysis of the water to be disinfected. Then, while performing the disinfection of the water to be disinfected by the oxygen generated during the electrolysis (oxidative disinfection by contact oxidation), the water to be disinfected containing a large amount of oxygen after the electrolysis is stored in the storage tank 1.
It is returned to the stored water 6 inside, and the stored water 6 in the water storage tank 1 is entirely disinfected.

用した場合にも問題はない。Of the oxygen generated during electrolysis, the oxygen atoms in the generation stage have particularly strong oxidizing power and can instantaneously and directly oxidize and disinfect the water to be disinfected. Therefore, the stored water 6 with the reduced residual chlorine concentration is
Even if it is stored for a long time in 1, the oxidative disinfection of oxygen generated during electrolysis can prevent or suppress the propagation of pathogenic bacteria and prevent the water quality from lowering. There is no problem when the stored water 6 in the tank 1 is used as drinking water.

However, since the water to be disinfected is electrolyzed in the closed vessel 12, the oxygen is electrolyzed. The water moves along with the water to be disinfected in the closed container 12 while bubbling in the water to be disinfected to disinfect the water to be disinfected. As a result, the water to be disinfected can be sufficiently disinfected by oxygen, and a large amount of oxygen dissolves in the water to be disinfected, increasing the dissolved oxygen concentration in the water to be disinfected, and shifting the water to be disinfected to one that is effective for living organisms. Good water quality can be achieved. Moreover, the water particles to be disinfected become finer by electrolysis,
Furthermore, it can be made effective water for living organisms. Then, the water to be disinfected after the electrolysis is returned from the sealed container 12 into the stored water 6 in the water tank 1, and the water in the water tank 1 and the electrolytic disinfection device
