Description
Technical Field

Background
Ozone, a strong oxidant, has a very high oxidation potential, 2.07 volts, much higher than 1.36 volts for chlorine and 1.28 volts for hydrogen peroxide, and is seen to be the strongest one in terms of oxidizing power in treating water. The strong oxidizing property of the ozone enables the ozone to become a broad-spectrum and high-efficiency bactericide, and the reaction time is short, the sterilization speed is high, and no residue or selectivity exists. Ozone is used as a clean and environment-friendly broad-spectrum bactericide and has been applied in the field of small household appliances. Among the methods for generating ozone, the method of electrically shocking air, which is mainly used in industry, is used in the largest amount of production at the most, and the equipment is bulky.

The ozone generator of the current water electrolysis method has been developed for years, and the research direction of the proton membrane electrode is formed. Corresponding catalysts have appeared as nanoscale catalysts. The whole generator consists of an anode assembly, a cathode assembly and a proton membrane, wherein the electrode adopts a coating oxide titanium electrode (DSA), and the DSA belongs to an enamel-electrocatalysis-semiconductor electrode. The anode assembly and the cathode assembly are fastened in different manners according to different connection manners of the anode assembly and the cathode assembly, and the cathode and the anode are directly connected by using screws most frequently.

The life of the current generators is short, typically in the thousands of hours.
