摘  要:
[目的]寻求一种有效降解含有机磷农药废水的方法。[方法]研究了Fenton反应的反应时间、pH值、H2O2与Fe2+浓度对降解率的影响,同时考察了光和超声波对反应的促进作用。[结果]对于125 mg/L的乐果溶液,在温度60℃,溶液pH值为3,H2O2加入量为5mmol/L,FeSO4.7H2O加入量为0.3 g条件下,30 min内降解率可达100%,延长反应时间为8 h,COD去除率可达100%。光与超声波对Fenton试剂有很强的协同催化作用,3 h内COD去除率可达90%。[结论]Fenton试剂可使有机磷农药有效降解。

摘  要:
[Objective] The aim of the study was to seek a good method for the degradation of organophosphorus pesticide wastewater containing dimethoate.[Method] The influence of reation time,pH value,the concentration of H2O2 and Fe2+ on degradation efficiency of Fenton reaction were analyzed,and the stimulating effects of photo and ultrasonic on Fenton reaction were also researched.[Result]Under the condition of 60 ℃,pH3,H2O2 5 mmol/L,the addition of FeSO4·7H2O 0.3 g,the degradation efficiency was 100% within 30 min,the COD removal efficiency could reach 100% in 8h.Furthermore,photo and ultrasonic could enhance the degradation ability of Fenton reagent,under the same condition,the COD removal efficiency could be 90% within 3 h.[Conclusion] Fenton reagent can be applied in the efficient degradation of organophosphorus pesticide wastewater containing dimethoate.
