摘　　要：北方某生活垃圾填埋场配套的3座渗滤液处理设施,工艺分别为:调节池+厌氧反应器+两级硝化反硝化系统+超滤系统+纳滤系统+反渗透系统、调节池+两级硝化反硝化系统+超滤系统+高压反渗透系统+反渗透系统和调节池+预处理生物转盘系统+一级硝化反硝化池+超滤系统+高压反渗透系统。通过对比运行数据,发现3座渗滤液处理设施在不同水质下对各主要污染物均有良好的去除效果,对COD、氨氮、总氮的平均去除率均在99.0%以上,设施内电导率降低率达95.0%以上。综合考虑能源消耗、运营成本、处理效果等因素,采用MBR系统+高压反渗透系统+反渗透系统代替MBR系统+纳滤系统+反渗透系统处理老龄化渗滤液具有较好的效果。Three leachate treatment facilities were equipped in a domestic wastelandfillin North China.The processes were regulating reservoir+anaerobic reactor+two stage nitrification and denitrification+ultrafiltration+nanofiltration+reverse osmosis,regulating reservoir+two stage nitrification and denitrification+ultrafiltration+high pressure reverse osmosis+reverse osmosis and regulating reservoir+pretreatment rotating biologicalcontactor+nitrification,and denitrification+ultrafiltration+high pressure reverse osmosis.By comparing the operation data,it was found that the three leachate treatment facilities all had good removal effects on the main pollutants under different water quality.The average removal rates of COD,ammonia nitrogen and total nitrogen were above 99.0%,and the electrical conductivity of the facility decreased by more than 95.0%.Comprehensively considering the factors such as energy consumption,operating costs and treatment effect,the process of MBR+high pressure reverse osmosis+reverso osmosis had better effect than the process of MBR+nanofiltration+reverse osmosis in the treatment of aged leachate.
