摘　　要：研究了Fe/C微电解和Fenton氧化处理印刷电路板废水的最佳条件和联合工艺的处理效果。结果表明,Fe/C微电解最佳工艺条件为:pH=2,Fe/C质量比为2∶1,投加药剂量为30 g/L,停留时间为30 min;Fenton氧化最佳工艺条件为:pH=3,H2O2投加量为6 mL/L,停留时间为2 h。将2种方法联用并进行中试实验,结果表明,对原水的COD去除率可达80%,而且Fenton反应可利用微电解产生的Fe2+,节约成本,运行稳定,效果良好。The combined techniques of Fe /C micro-electrolysis and Fenton reagent for treating printed circuit board wastewater were studied.Results show that the appropriate parameters of Fe / C micro-electrolysis are as follows： pH = 2,Fe / C mass ratio of 2∶ 1,iron and carbon dosage of 30 g / L,reaction time of 30 min;the appropriate parameters of Fenton reagent are pH = 3,H 2 O 2 dosage of 6 mL / L,reaction time of 2 h.The results of pilot scale test show that the COD removal,rate was 80%.And Fenton reagent could take use of Fe2 ＋generating in Fe / C micro-electrolysis.The combined techniques are highly efficient in removal of pollutants,stable in operation and saving cost.
