The removal capacity of organic matter by catalytic oxidation of honeycomb ceramics was higher than that by ozone oxidation. The maximum removal rate of FP was about 2 times higher than that of ozonation. In the continuous flow test, the removal effect of catalytic oxidation on UV2s4 is obvious at low ozone dosage, and the removal rate of UV2s4 is 16.7% higher than that of ozone at 1 mg/L, which is the result of the high proportion of horizontal push flow in the honeycomb ceramic catalytic reactor and the rapid increase of liquid phase ozone concentration. In addition, the catalytic oxidation of honeycomb ceramics on BrO; When ozone dosage is L mg/L, catalytic oxidation effluent BrO; The content is 38.8% lower than that of ozone oxidation.activated carbon for gold recovery
Activated carbon catalyst can promote the decomposition of ozone. The consumption rate of liquid phase ozone in activated carbon catalytic secondary oxidation process is 71.2% higher than that in ozone secondary oxidation process. The analysis of the relationship between ozone consumption and organic matter content in activated carbon catalytic secondary oxidation process shows that activated carbon can react directly with ozone or act as a free radical initiator in the process of ozone decomposition, especially when the organic matter content in water is low. When ozone dosage is L mg/L, the MIB removal rate of catalytic secondary oxidation is about L times higher than that of ozone secondary oxidation. When the concentration of ozone in water is about 1.5 mg/L, the catalytic secondary oxidation makes BrO; The concentration decreased by 0.04mg/L.activated carbon wholesale
