All the water in the fresh water outlet pipeline 51 is collected in the fresh water outlet main pipeline 53, and the electrolysis module 91 sterilizes the water in the fresh water outlet main pipeline 53, so that the water flowing out of the fresh water outlet main pipeline 53 is prevented from being turbid and smelly.

After the water enters the electrolysis module 91, under the action of the electric field, anions migrate to the anode electrolyte sheet 912 and cations migrate to the cathode electrolyte sheet 913.
In the vicinity of the anolyte sheet 912, chloride ions lose electrons more readily than other anions and are oxidized to chlorine gas:
2Cl--2e-—→Cl2
in the vicinity of the catholyte sheet 913, hydrogen ions are reduced to hydrogen gas, more readily available electrons than other cations:
2H++2e-—→H2
the hydrogen ions continuously get electrons on the cathode electrolyte sheet 913 to generate hydrogen gas to be discharged, which destroys the ionization balance of water near the cathode electrolyte sheet 913 and generates more hydroxyl OH-And an alkaline environment is formed. Chlorine gas generates hypochlorite ions in an alkaline environment:
Cl2+4OH-—→2ClO-+2H2O
hypochlorite ions have strong oxidizing property, and can act on organic matters and bacterial pollutants to play a role in cleaning the electric purification module 1.
The concentration of hypochlorite ions generated by the electrolysis module 91 can be changed by changing at least one of the flow rate of the inflow water to the electrolysis module 91, the voltage applied to the electrolysis module 91, and the pitch between the anode electrolyte sheet 912 and the cathode electrolyte sheet 913. In other words, the concentration of hypochlorite ions generated by the electrolysis module 91 depends on the flow rate of the feed water, the applied voltage, and the distance between the anode electrolyte sheet 912 and the cathode electrolyte sheet 913. The concentration of the generated residual chlorine is controlled within the range of 0.01-1.0mg/L, the effects of preventing the deposition of organic matters in the electric purification module 1 and the breeding of bacteria in a water purification system are achieved, meanwhile, the ion exchange membrane cannot become brittle under the action of the electric purification module 1, and the performance of the ion exchange membrane is favorably maintained.
