ZSM⁃5 molecular sieve was used as carrier, cerium (Ce), manganese (Mn), nickel (Ni) and copper (Cu) were used as active components to prepare metal⁃supported catalyst to catalyze ozonation treatment of phenol wastewater. The catalyst was prepared by impregnation method and characterized. The effects of active components, ozone dosage, catalyst concentration and pH on the treatment of phenol wastewater were investigated. The results showed that Ce⁃ZSM⁃5 had the best catalytic effect and COD removal rate under the conditions of pH=7, catalyst concentration of 1.00 g/L, ozone dosage of 44.0 mg/min and reaction time of 60 min. It is 85.74%. When Ce⁃ZSM⁃5 is added, about 80% of the ozone can be saved. It shows good stability which the COD removal ratio reached about 70% after the catalyst repeatedly used for 7 times.
