【Abstract】 Cu/artificial zeolite catalyst was prepared by impregnation method and its catalytic degradation of coal chemical wastewater by ozone oxidation was studied. The effects of calcination temperature, Cu（NO₃）₂ impregnation concentration, pH, ozone dosage and catalyst dosage on wastewater treatment were studied and the optimum preparation conditions of catalyst were obtained. The degradation mechanism of coal chemical wastewater by ozone-catalyzed oxidation was studied by adding tert-butanol, and the water samples treated under the optimal working conditions were analyzed by UV spectrum. Results showed that the optimum calcination temperature and impregnation concentration were 400 ℃ and 0.8 mol/L, respectively. The optimal pH, ozone ventilation and catalyst dosage were 7.8, 2 g/h and 60 g/L, respectively. Under the optimal preparation and working conditions, the removal rates of chemical oxygen demand（COD） and total phenol in coal chemical wastewater reached 72.4% and 51.9%, respectively, and the organic compounds in coal chemical wastewater were effectively degraded.·OH played an important role in the degradation of coal chemical wastewater.更多还原
