摘　　要：对于含有较高污染物浓度的垃圾渗滤液,采用MBR工艺处理,运行效果稳定、效率高。工程实践表明,MBR进水COD应满足硝化及反硝化的要求,生物池水温取值宜不低于25℃,生物池混合液污泥浓度宜取12～20 g/L,污泥龄宜取15～25 d,剩余污泥产率宜取0.15～0.30kgVSS/kgCOD。MBR process has stable operation effect and high efficiency in treatment of landfill leachate with high concentration of pollutants. The engineering practice shows that the influent COD should meet nitrification and denitrification requirement. The temperature, mixed liquor suspended solid concentration, sludge age and excess sludge yield rate should be above 25℃, 12 to 20 g/L, 15 to 25 d and 0. 15 to 0. 30 kgVSS/kgCOD respectively.
