摘　　要：研究了Fenton试剂处理机械加工清洗废水的影响因素及其适宜操作条件。实验结果确定的适宜操作条件为:在原水COD_(Cr)约2 000 mg/L时,n_(H_2O_2)/n_(Fe^(2+))=37.6,H_2O_2的投加量40 mL/L,pH=4,反应时间2.5 h,此时COD_(Cr)的去除率可达91.4%。同时考察了聚丙烯酰胺与Fenton试剂的协同效果。适宜操作条件下COD_(Cr)的去除率可达93.2%。The influencing factors and optimal operating conditions for the treatment of cleaning wastewater in machine finishing using Fenton reagent are studied.The optimal operating conditions determined by experiment are as follows：the COD_（Cr） of the wastewater is about 2 000 mg/L,n_（H_2O_2：n_（Fe^（2＋））=37.6,the dosage of H_2O_2 is 40 mL/L,pH value is 4 and the oxidation time is 2.5 h. Under these conditions,the COD_（Cr） removal rate is up to 91.4%.Meantime,the synergic effect of PAM cooperated with Fenton reagent is also studied.Under the optimal operating conditions,the COD_（Cr） removal rate is up to 93.2%.
