摘　　要：垃圾渗滤液处理新标准实施后逐渐形成了"预处理/厌氧+膜生物反应器+膜深度处理"组合工艺,本工艺保证了污水处理的连续稳定运行及达标排放。分析了垃圾渗滤液的特点和新标准下垃圾渗滤液处理的工艺选择,并对国内主流工艺特点进行了总结;对"预处理+膜生物反应器(MBR)+膜深度处理"组合工艺的流程进行了详细说明,并对主要工艺设计参数进行了归纳总结,分析了垃圾渗滤液处理工艺在设计运营中存在的二次污染、泡沫外溢、能源回用等问题并提出了改进措施建议。After the implementation of new standards, the combined process of pretreatment/anae- robic treatment, membrane bioreactor and advanced treatment with membrane technology has been gradu- ally formed, which can ensure the continuous and stable operation of the system and the effluent to meet the discharge standards. The characteristics of landfill leachate and selection of treatment process under the new standards were analyzed, and the features of domestic mainstream technologies were summarized. The flow of the combined process was described, and the main design parameters of the combined process were summarized. Problems existing in operation of the treatment process, such as secondary pollution, foam overflow, energy reuse and so on were analyzed, and improvements were proposed.
