摘  要:
采用芬顿氧化-微电解相结合的方法对噻唑磷废水进行了处理研究,探讨了影响处理结果的各种要素。试验结果表明芬顿反应的最佳条件是:废水初始pH=3.5~4,H_2O_2投加量为5 mL/L,10%FeSO_4的量为6g/L,反应时间为1.5 h;芬顿出水直接进行微电解,微电解停留时间为4 h。经过预处理后,废水的化学需氧量去除率达到80%。处理后废水的5日生物需要量/化学需氧量由0.17提高到0.39。

摘  要:
The processes of micro-electrolysis and Fenton oxidation have been combined and used for pretreating fosthiazate wastewater and the parameters that affect the emciencies of the wastewater treatment have been discussed.The results showed that the best condition for Fenton reaction is:wastewater initial pH = 3.5~4,H_2O_2 dosage of 5 mL / L,10%FeSO4 amount of 6 g/L, reaction time of 1.5 hours.Micro-electrolysis was directly taken place,after Fenton treated water and micro-electrolysis stayed for four hours.After pretreatment,the wastewater COD removal rate reached 80 percent.Treated wastewater BOD_5/ COD increased from 0.17 to 0.39.
