- Abstract:
- The ozone catalytic oxidation technology has some problems in wastewater treatment, such as poor treatment efficiency and low ozone utilization rate. Therefore, the ozone catalyzed oxidation process and equipment were optimized, and a new type of ozone catalytic oxidation device was designed by setting different outlet heights of the ozone tower, increasing exhaust spray absorption, arranging a two-stage gas intake and coupling hydrogen peroxide. The performance of this device for the treatment of the biochemical effluent from an enterprise in Shandong Province was investigated. The best treatment performance of the wastewater was obtained when the outlet height of the ozone tower was above 7.0 m, a spraying was added before ozone exhaust, an air intake was arranged at the bottom, and the hydrogen peroxide was added in an appropriate amount. Under these conditions, the ozone utilization rate and COD removal efficiency of the wastewater were both increased by about 10%.
