摘　　要：中心城区垃圾转运站在垃圾压缩过程中会产生渗滤液,其特点是渗滤液水量小、水质复杂、水量波动大,出水一般执行CJ 343-2010标准。常规"预处理+厌氧+膜生物反应器+纳滤/反渗透"组合工艺虽然可保证出水水质达标,但无法适应中心城区垃圾转运站占地面积小、周边建筑密集、环境敏感点多的特点。针对上述问题,推荐采用"预处理+HBR(高负荷生化反应器)+MBR(膜生物反应器)"的新型组合工艺处理垃圾转运站渗滤液,保障出水水质达到接管标准。Refuse transfer station（RTS）in center city will produce leachate during the compression process.The amount of leachate is small and its wastewater quality is complicated.And the quality of leachate vary a lot.Its effluent standard is CJ 343-2010.Although the general combination process of＂pretreatment-anaerobic-MBR-NF/RO＂can ensure effluent water quality standards,it cannot adapt to the characteristics of the RTS in center city such as small occupied area,dense surrounding buildings and intensive environmental sensitive points.For these reasons,it is recommended to use the new combined process of ＂pretreatment-HBR（high-load bio-reactor）-MBR＂to treat the leachate in RTS,which would ensure that water quality could meet the effluent standard.
