とができ、残留塩素値の経時的な低下を防止できる。With the water to be disinfected flowing into the electrolysis chamber 15 of the sealed container 12, a voltage is applied between the electrodes 22 and 23 from the large-capacity power supply unit 53 or the small-capacity power supply unit 54 by the control means 55, and
The salt content in the water to be disinfected passing through
Electrolyze between. That is, since the water to be disinfected is tap water and salt remains in the water to be disinfected, each of the electrodes 22, 23
When a direct current is applied between the electrodes 22, 23, Cl 2 is generated at the anode and NaOH is generated at the cathode, and both react to form sodium hypochlorite NaClO, which is dissolved in the water to be disinfected. I do. Then, since the water to be disinfected after electrolysis is returned to the stored water 6 in the water tank 1, the residual chlorine value of the water to be disinfected can be increased by utilizing the salt in the stored water 6, and the residual chlorine can be increased. It is possible to prevent the chlorine value from decreasing over time.

止することができる。Therefore, even in the case of tap water, if the residual chlorine value becomes 0.1 ppm or less and the disinfecting power is reduced while staying in the water storage tank 1, if pathogenic bacteria and the like in the air enter together with the rainwater. The water quality decreases as it breeds,
The residual chlorine content of the water 6 in the water storage tank 1 is constantly maintained at, for example, 0.15 ppm or more by sodium hypochlorite generated during electrolysis of the water to be disinfected by directly utilizing the salt content remaining in the water. The deterioration of the water quality of the stored water 6 in the tank 1 can be prevented.

The pump automatically pumps up the stored water 6 in the water storage tank 1 with the pump 7 according to the signal, and directly electrolyzes the salt content in the water to be disinfected. Is very easy. 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 a pumping point and a return point of the storage water 6, the storage water 6 in the water storage tank 1 can be efficiently treated.

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.

The application of the voltage to each of the electrodes 22 and 23 is continued to switch from electrolysis of the salt to electrolysis of the water to be disinfected, and oxygen and hydrogen are generated 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 returned to the storage water 6 in the water storage tank 1. Then, the stored water 6 in the water storage tank 1 is entirely disinfected.

Therefore, even if the stored water 6 with the reduced residual chlorine concentration is stored in the water storage tank 1 for a long time while the inflow water is stopped, propagation of pathogenic bacteria, etc., due to the oxidative disinfection of oxygen generated during electrolysis, etc. Therefore, there is no problem even if the stored water 6 in the water storage tank 1 is subsequently used as drinking water.

に生命体に有効な水にすることができる。If the oxygen generated by the electrolysis is left open to the atmosphere, the oxygen diffuses into the atmosphere while bubbling through the water and disappears. 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. For this reason, the water to be disinfected can be sufficiently disinfected by oxygen, and a large amount of oxygen dissolves in the water to be disinfected, so that the dissolved oxygen concentration in the water to be disinfected becomes large, and the water to be disinfected is transferred to an effective water for living organisms. Water can be improved. In addition, the water particles to be disinfected are made finer by the electrolysis, and the water can be made more effective for living organisms.

Electrolyze the water to be disinfected pumped in step 7 to disinfect and improve the quality of the stored water 6 in the water tank 1.

That is, if there is an ON signal from the control unit 55, a large voltage is supplied between the electrodes 22 and 23 from the large capacity power supply unit 53 to flow a large current, and sodium hypochlorite is generated according to the supplied power amount. . If there is an off signal from the control means 55, the application of the large voltage from the large-capacity power supply unit 53 is stopped, and at the same time, a small voltage is supplied between the electrodes 22 and 23 from the small-capacity power supply unit 54 to flow a small current.

Etc. can be prevented. It is possible to prevent the deterioration and wear of the saw electrodes 22 and 23 themselves.

Can be electrically eluted, and the initial performance can be maintained while reducing maintenance. Hydrogen and oxygen are generated in the electrolysis chamber 15 during electrolysis of the water to be disinfected.Especially oxygen can be used to improve the water quality, but the state of the bubbling of oxygen and the condition of the electrodes 22 and 23 can be seen through the inspection window 44. For example, it can be easily visually inspected even from the outside of the sealed container 12.
