摘　　要：利用赤泥制备复合混凝剂PAFCS(聚合硫酸氯化铝铁)并以炉渣作为吸附剂对垃圾渗滤液进行预处理,对SS和色度的去除率分别为84%和92%,对COD的去除率可达53.3%,还提高了渗滤液的可生化性。然后采用两段SBR法对垃圾渗滤液进行生化处理,结果显示:通过对降解COD和氨氮的两类微生物分别进行培养,保持了较高的生物活性,进而提高了对此类高浓度难降解废水的处理效率。通过两段SBR处理以后,COD、BOD和氨氮的去除率分别为88%、94%和89%,出水水质达到了国家《生活垃圾填埋污染控制标准》(GB 16889—1997)的二级标准。For the treatment of landfill leachate, the coagulation and absorption of Polymeric Aluminum Ferric Chloride Sulfate （PAFCS） and furnace slag were used in the pretreatment. The results show that the removal efficiencies of SS, chroma and COD are 84% , 92% and 53.3% respectively in this step. The two-stage SBR biochemical process was applied for further treatment, the purpose of which is to cultivate the microorganisms focusing on COD and NH4^＋ -N. After the whole process, the removal efficiencies of COD, BOD and NH^4＋ -N can reach 88% , 94% and 89% respectively. The effluent can meet the Ⅱ -chass criteria specified in Standard for Pullution Control on the Landfill Site for Domestic Waste（ GB 16889 - 1997 ）.
