摘　　要：采用Fenton氧化法处理印染废水,探究体系下初始pH值、H2O2投加量、FeSO4投加量、反应时间对废水中COD去除率的影响。结果表明,处理100 mL初始COD浓度为1465 mg/L的印染废水时,Fenton体系的最佳反应条件为:初始pH为3、H2O2为0.81 mL、FeSO4为1 mmol、反应时间120 min,此时COD去除率为87.34%。The system of Fenton oxidation was employed to treat printing and dyeing wastewater,the effects of different influential factors in the systems were investigated,including the initial pH,the dosage of H2O2 and FeSO4,and reaction time.The results showed that when treating 100 mL of printing and dyeing wastewater with an initial COD concentration of 1465 mg/L,the Fenton system can remove COD at the rate of 87.34%under the optimal reaction conditions,which is,the initial pH is 3,H2O2 is 0.81mL,FeSO4 is 1mmol,and the reaction time is 120min.
