Advanced oxidation processes generate a large amount of highly oxidative hydroxyl radicals (·OH) in situ through the combined action of ozone, hydrogen peroxide, ultraviolet light, catalysts, etc.
Hydroxyl radicals non-selectively attack trace organic matter, pesticide residues, algal toxins, disinfection byproduct precursors and other pollutants in water, destroy their molecular structures, and gradually oxidize and decompose them.
These pollutants are finally mineralized into carbon dioxide, water and inorganic salts, achieving advanced purification of drinking water.
Meanwhile, this process can also oxidize some inorganic pollutants and destroy the cell structure of microorganisms, providing auxiliary disinfection.
