摘要
结合青岛市某生活垃圾处理场工程实例,介绍了MBR工艺处理垃圾渗滤液的工艺流程、原理等,分析了MBR工艺处理垃圾渗滤液的特点和优势。垃圾渗滤液经过MBR工艺处理,生化部分采用前置反硝化/硝化工艺,再经纳滤/反渗透等膜分离技术和其他方法处理,最终流出液水质可以达到《生活垃圾填埋场污染控制标准》(GB 16889-2008)。
Combined with an engineering project in Qingdao City, the technical process and principles of membrane bio - re- actor（MBR） in treating landfill leachate are introduced, and the characteristics and advantages of MBR process are analyzed. MBR adopts denitrification and nitrification as bio - treatment measures. Then, the landfill leachate is treated by nanofihration and reverse osmosis as well as other treatment methods. The final effluent can meet the Standard for Pollution Control on the Land- fill Site for Domestic Waste（ GB 16889 - 2008 ）.
