摘　　要：该文以河北省某生活垃圾焚烧发电项目500 m^(3)/d渗滤液处理系统为研究对象,对“预处理+厌氧UASB+MBR(两级A/O+外置式超滤UF)+纳滤(NF)+反渗透RO”的组合工艺流程、各处理单元设计参数、调试运行效果及运行成本进行详细介绍,分析厌氧系统、MBR系统对渗滤液中COD、氨氮指标的去除效率。实际运行效果表明,该系统垃圾渗滤液出水满足设计出水水质标准,其吨水处理成本为51.73元。This paper takes the 500 m^(3)/d leachate treatment system of a municipal solid waste incineration power generation project in Hebei Province as the research object,and introduces in detail the combined process flow of"pretreatment+anaerobic UASB+MBR(two-stage A/O+external ultrafiltration UF)+nanofiltration(NF)+reverse osmosis RO",the design parameters of each treatment unit,debugging operation effect and operation cost,and analyzes the removal efficiency of COD and ammonia nitrogen in leachate by anaerobic system and MBR system.The actual operation results show that the effluent of the landfill leachate of the system meets the designed effluent quality standard,and the treatment cost per ton of water is CNY 51.73.
