摘　　要：彭州市垃圾填埋场为了实现渗滤液处理组合工艺"SBR+混凝沉淀"系统的快速恢复运行,减轻渗滤液与生活污水合并处理对污水厂造成的冲击,采用接种城市污水处理厂活性污泥的方法,先驯化污泥再进行工艺调试。结果表明,系统经恢复调试后运行稳定,对渗滤液中COD、氨氮、SS的去除率分别达到(71.6%~76.7%)、(59.4%~60.5%)、(59.5%~88.9%),处理费用为6.9元/m^3,但不能达标排放。通过实验室小试验证,在SBR生化处理前降低氨氮浓度将使组合工艺处理出水水质达到《生活垃圾填埋污染控制标准》(GB 16889—1997)的三级排放标准。In order to reduce the impact of combined treatment of leachate and domestic sewage on the operation of wastewater treatment plant, and achieve rapid recovery of the combined leachate treat- ment process of SBR/coagulation and sedimentation in Pengzhou landfill site, the activated sludge from municipal wastewater treatment plant was used as the inoculated sludge. After the sludge acclimation, the commissioning of the combined process was performed. The results demonstrated that the process system could operate stably after recovery and commissioning. The removal rates of COD, ammonia nitrogen and SS reached 71.6% to 76.7%, 59.4% to 60.5% and 59.5% to 88.9%, respectively. The treatment cost was 6.9 yuan/m^3, but the effluent quality could not meet the national discharge standards. The bench scale test revealed that the effluent quality of the combined process could meet the third class crite- ria specified in the Standard for Pollution Control on the Landfill Site for Domestic Waste （GB 16889- 1997） by reducing ammonia nitrogen concentration before the SBR biological treatment.
