摘　　要：以橡胶厂的工业废水为研究对象,探讨了各种因素对Fenton氧化后废水混凝处理效果的影响,并对H2O2、FeSO4·7H2O和Fe2(SO4)3用量进行L9(33)正交试验,确定Fenton氧化-混凝联合工艺处理橡胶废水的最佳反应条件为:质量分数30%的H2O2、FeSO4·7H2O和Fe2(SO4)3投加量分别为2mL、0.3g和0.3g。与Fenton氧化法和直接混凝法相比,Fenton氧化-混凝联合工艺对橡胶废水处理效果更好,对COD去除率明显高于单独采用2种方法对COD去除率的总和。With rubber wastewater as the object of study, H2O2 dosage, coagulation solution pH value, coagulation dosage and reaction time which had notable effect on the coagulation process with Fenton preoxidation water were investigated. According to L9（3^3） orthogonal experiments with H2O2（30%） dosage, FeSO4·7H2O dosage and Fe2（SO4）3 dosage, the optimal dosage were 2 mL, 0.3 g and 0.3 g respectively. The united process had better COD treatment result than that of Fenton oxidation or direct coagulation.
