摘　　要：采用Fenton氧化-好氧生物法联合处理经过生物法处理的碱减量废水,运用正交实验确定最佳的Fenton氧化反应参数,验证该组合工艺的可行性及运行效果。结果表明,废水经Fenton氧化-好氧生物法的处理可以获得很好的处理效果,相比于单一的好氧生物法,可以减少水力停留时间,碱减量废水的Fenton氧化反应的最佳反应条件是:pH=3.5,H2O2加入量为1.5mL/L,FeSO4·7H2O加入量为400mg/L。The Fenton oxidation-biological method was combined to treat the alkali-decrement wastewater treated by biological method,and the optimal Fenton oxidation reaction parameters were determined by orthogonal test to verify the feasibility and operation effect of the combined process.The results showed that the wastewater could be treated by Fenton oxidation-aerobic biological method,and the hydraulic retention time could be reduced compared with the single aerobic biological method.The optimum reaction conditions for Fenton oxidation of alkali-decrement wastewater were:pH =3.5,the amount of H2O2 added was 1.5 mL/L, and the amount of FeSO4·7H2O was 400 mg/L.
