摘　　要：探索了微电解工艺处理毒死蜱生产废水的可行性,以COD和TOC同时作为指标,分别考察了反应时间、初始pH、H2O2加入量等工艺参数对降解效果的影响,得出了最佳工艺参数组合。试验发现,H2O2加入对反应造成不良影响,以不添加为宜;对可能的机理进行了分析。在此基础上进行了双级微电解试验,COD和TOC的总去除率均达到85%以上。结果表明微电解是一种非常经济适用的农药废水处理工艺,并显示了其实际应用的前景。The feasibility of treating chlorpyrifos wastewater by micro-electrolysis was investigated by using COD,TOC value as indexes. and different operating parameters such as reaction time, initial pH and H2O2 dosage were studied to achieve the optimal combination. While H2O2 seemed to have complex influence on the degradation process, it was abandoned and the possible mechanism was discussed. The two-band experiments were carried out based on the obtained results and the removal rate of COD and TOC value both exceeded 85%. The option of micro-electrolysis was proved to. be very economical and adaptable in treating pesticides wastewater and showed possibilities for real application.
