NOVELTY - A sewage treatment oxidation catalyst comprises catalyst carrier and active component. The catalyst carrier comprises clay, activated carbon and graphene. The active component comprises activated alumina, manganese iron ore, rare earth element, and cerium-zirconium powder. The oxidation catalyst is prepared by mixing active component with organic solvent additive and then calcining with catalyst carrier. USE - Sewage treatment oxidation catalyst. ADVANTAGE - The sewage treatment oxidation catalyst has improved durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the sewage treatment oxidation catalyst, which involves performing acidic oxidation pretreatment of catalyst carrier, mixing active component with catalyst carrier, drying catalyst carrier and calcining.
