Abstract: Three methods,including UV,O3 and UV/O3,are separately used to treat with actual biochemical tail-water of the sewage treatment plant in a chemical industrial park.Influences of UV lamp power,irradiation time,O3 dosage and reaction initial pH on the reaction are explored.The results show that the treatment effect by UV/O3 is larger than the sum of that by UV and O3,representing a synergistic effect.The content of COD in tail water drops from 82.3 mg·L-1 to 49.5 mg·L-1,with a removal rate of 40% when the power of UV lamp is 16 w,the dosage of O3 is 0.6 mL·min-1,the initial pH is 7.1,and the duration of irradiation is 120 min.The effluent reaches grade A of China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918—2002).
