摘　　要：采用Fenton试剂氧化-混凝沉淀法深度处理焦化生化处理二沉池出水,考察了H2O2投加量、Fe2+/H2O2(物质的量比)、PFS(聚合硫酸铁)投加量、pH值、反应时间对TOC和COD去除效果的影响,确定了适宜的反应条件。试验结果表明,TOC和COD去除率最高分别达到90.7%和72.7%,出水COD浓度达到GB 8978—1996《国家污水综合排放标准》一级。The effluent from the secondary sedimentation tank of coke wastewater biochemical treatment pool was treated by Fenton oxidation-flocculation precipitation method.The effects of hydrogen peroxide dosage,the mole ratio of Fe2＋/H2O2,the dosage of PFS,the pH value and reaction time on TOC and COD removal rate are investigated and the appropriate reaction conditions are determined.The experimental results show that the removal rate of TOC and COD reaches 90.7 % and 72.7 % respectively and COD effluent quality conforms to the first grade of the National Integrated Wastewater Discharge Standard（GB 8978—1996）.
