摘　　要：研究了TiO2光催化降解有机磷农药乐果废水的影响因素,获得的适宜工艺条件为:TiO2用量0.4 g/L,乐果初始浓度20 mg/L,曝气量23 L/h,在强酸性及碱性介质中均有利于乐果废水的降解。加入电子接受体Fe3+、H2O2能较大地提高乐果废水降解率。Photocatalytic degradation of pestcides wasteater by catalyst TiO2 investigated. The suitable conditions for degrading the process were obtained： consumption 0.4 g/L of TiO2, rogor initial density 20 mg/L, the airflow 23 L/h, favorable to the degradation of the organic matter in the wastewater in strong acid and alkaline medium. The degradation efficiency of rogor increased greatly when the electron acceptor Fe^3＋ or H2O2 was added.
