Problems solved by technology

[0002] With the development of the chemical industry and the wide application of chemical synthesis products, the types and contents of refractory organic pollutants and new pollutants in the water environment have increased significantly. With the gradual strengthening of my country's environmental awareness and the continuous upgrading of sewage discharge standards, Relevant units at all levels have strengthened wastewater treatment efforts to meet national water treatment standards. Ozone catalytic oxidation technology for oil refinery wastewater has been widely concerned and applied due to its high treatment efficiency and simple operation. Due to its oxidation selectivity and ozone utilization rate Low cost, high operating cost and other issues, the promotion and application of ozone oxidation technology has been severely restricted, therefore, it is necessary to prepare an ozone catalyst with high catalytic activity, good stability, low preparation cost and no secondary pollution
