MBR工艺处理垃圾渗滤液几种典型工艺流程分析

Analysis of Several Typical Landfill Leachate Treatment Methods Using MBR Process

MBR是处理含有高浓度COD及高浓度氨氮的垃圾渗滤液的主流工艺,得到了业内的普遍认可。目前国内MBR工艺主要有外置式一级硝化反硝化MBR、外置式二级硝化反硝化MBR、设置中间沉淀池的外置式二级硝化反硝化MBR、内置式二级硝化反硝化MBR四种类型,从工程实践角度分析了这几种MBR工艺的适用条件和各自的优缺点,具体应用时应根据工程实际情况慎重选择。

MBR is the mainstream process for treating leachate containing high concentrations of COD and ammonia. In China, there are four main types of MBR processes including external primary ni- trification and denitrification MBR, external secondary nitrification and denitrification MBR, external sec- ondary nitrification and denitrification MBR with intermediate settling tank and built-in secondary nitrifi- cation and denitrification MBR. The advantages, disadvantages and applicable conditions of those four types of MBRs were analyzed from engineering practice. It should be carefully selected according to the specific project application
