摘　　要：采用水解酸化-好氧-深度处理(混凝沉淀+Fenton氧化法)工艺处理制浆造纸废水,确定了水解酸化反应器、好氧反应器的最佳运行参数,考查了不同混凝药剂对CODCr去除率的效果及最佳投药量,并对混凝处理后出水进行了Fenton试剂氧化处理。结果表明:经生化处理后CODCr去除率可达72%左右,再经过混凝沉淀+在Fenton试剂氧化的基础上投加絮凝剂PAM强化处理,系统出水CODCr可降至100 mg/L以下。Hydrolysis acidification-aerobic process-advanced waster treatment(Coagulating sedimentation+Fenton oxidation process)was conducted to treat the pulp and papermaking wastewater,the best running parameters of the anaerobic reactor and the aerobic reactor has been identified,the different coagulatant agents and the best amount of coagulants added on the COD Cr removal rate has been examined,and Fenton reagen process were attempted to the effluent of Coagulation treatment.The results showed that after biochemical system,the removal efficiencies of COD Cr is 72%,and after Coagulating sedimentation+adding flocculant PAM on the basis of Fenton oxidation process,the system effluent COD Cr can be reduced to 100 mg/L.
