Ozone oxidation catalytic technology is an efficient deep treatment method for wastewater and has become a hot topic in the field of sewage treatment in recent years. Compared to ozone used as a standalone oxidant, ozone in the presence of a catalyst forms hydroxyl radicals (·OH) that react with organic compounds at a higher rate and with stronger oxidation, allowing for the oxidation of almost all organic substances. The catalyst utilizes the strong oxidative properties of ozone to directly oxidize organic compounds in water into CO₂ and H₂O, or to decompose large organic molecules into smaller ones, making them easier to degrade.
