[0002] In the existing industrial wastewater treatment process, the advanced oxidation method can directly mineralize or improve the biodegradability of organic wastewater with poor biodegradability and large relative molecular mass. The ozone oxidation process has good oxidation effect, strong decolorization ability and no secondary pollution, is the most representative and widely used advanced oxidation method in the advanced oxidation process, has strong ability to remove organic pollutants, can remove phenol, cyanide and other pollutants in water, and can also be used to decompose pollutants such as alkyl benzene sulfonate (ABS), protein, amino acid, organic amine, lignin, humus, heterocyclic compound and chain unsaturated compound in wastewater. At the same time, the ozone oxidation method also has very good effect on the decolorization treatment of printing and dyeing wastewater, so the ozone oxidation method has good application prospect.
