The high-integration bipolar electrolytic ozone generating stack technology is adopted in the system, and the Proton Exchange Membrane (PEM) electrolytic ozone generating stack using the technology generates high-concentration high-purity ozone (more than or equal to 20 percent by weight percent) as an ozone source on a special anode/solution interface under the action of low-voltage direct current. The electrochemical reaction principle is H 2O→2H++2e-+1/3O3. High-concentration ozone is very soluble in water, and high-concentration ozone water is generated.
The high-concentration ozone water (high-efficiency broad-spectrum disinfectant) is prepared on site by utilizing the high-concentration ozone gas source and the gas/water mixing device of the sanitary-grade high-efficiency turbine pump, the concentration of the ozone water is more than or equal to 15mg/L, and the disinfection requirement of a purified water storage and distribution system is met.
