Abstract: A method for preparing a supported two-component metal oxide ozone catalytic oxidation catalyst for an advanced treatment of a petrochemical wastewater is provided. The supported two-component metal-oxide ozone catalytic oxidation catalyst is prepared from commercially-available active alumina balls by the steps of carrier activation, impregnating liquid preparation, carrier impregnation, catalyst roasting, and catalyst cleaning. The supported two-component metal oxide ozone catalytic oxidation catalyst has product stability, is reusable, and is of significance in application of ozone catalytic oxidation technologies as well as energy conservation and consumption reduction for petrochemical wastewater treatment plants.
