摘　　要：研究了超声波辅助光催化(US/UV/TiO2)处理蔗渣浆CEH漂白废水的效率,分析了废水的水质特性和经过US/UV/TiO2处理后氯酚等有机物的变化情况,并且对比了其它废水处理技术与US/UV/TiO2联合使用的效果。结果表明:该废水的可生化处理性差并且有机化合物是废水COD的主要来源;经过12h处理后,大多数有机物被完全矿化;H2O2、Fenton试剂和活性炭与US/UV/TiO2联用后,大大提升了反应速率。US/UV/TiO2作为漂白废水深度处理技术是可行的。The efficiency of CEH bleaching effluent of bagasse pulp treated by ultrasonic photocatalytic degradation （US/UV/TiO2） technology was studied. The effluent feature and the reaction condition of organic compound such as chlorophenols treated by US/UV/TiO2 were analyzed. The results showed that the biochemical feature of the effluent was not good and organic compounds were the main source of COD. Within 12 h, most of compounds were mineralized by US/UV/ TiO2, and adding H2O2, Fenton reagent and activated carbon into the system could improve the rate of degradation greatly. Therefore US/ UV/TiO2 Js feasible for advanced treatment of the CEH bleaching effluent.
