SUPPORTED TWO-COMPONENT METAL OXIDE CATALYST FOR ADVANCED TREATMENT OF PETROCHEMICAL WASTEWATER AND PREPARATION METHOD THEREFOR

摘要

Disclosed is a method for preparing a supported two-component metal oxide catalytic ozonation catalyst for the advanced treatment of petrochemical wastewater. The method involves subjecting commercially available activated alumina balls to the steps of carrier activation, impregnation solution preparation, carrier impregnation, catalyst calcination, and catalyst cleaning to obtain the supported metal oxide catalytic ozonation catalyst. The method is simple, low in cost and easy to prepare. The prepared catalyst can efficiently remove a secondary effluent of petrochemical wastewater with a relatively high selectivity. The product has a good stability, is reusable, and is of great significance to the application of catalytic ozonation technology and to saving energy and consumption reduction in petrochemical wastewater treatment plants.
