摘　　要：选用新型生物反应器填埋场(由卫生填埋场和产甲烷反应器组成),进行了渗滤液处理效能及产能特性研究。结果表明:新型生物反应器填埋场有助于渗滤液中有机物进行分相降解,在渗滤液的净化和填埋场垃圾的稳定化上优于渗滤液直接循环的填埋场。产甲烷反应器处理垃圾渗滤液时,在进水的VFA浓度大于3000mg/L条件下,CODCr去除率76%～94%;容积CODCr去除率0 88～4 85g/(L·d);容积沼气产率0 5～2 85L/(L·d)。A study was conducted on the characteristics of bioreactor-landfill system which was composed of sanitation landfill and methane bioreactor.The results showed that the system helps the degradation of organic pollutants in leachate to be divided into two-phases.It also compares the operation of this system with leachate-recirculation-landfill system on leachate treatment and solid waste of landfill stabilization which was superior to the leachate directhy circulated landfilll.The methane bioreactor treatment results were:when the influent VFA concentration were more than 3000mg/L,COD removal rate of 76%—94% volumetric COD removal rate of (0.88～)4.85g/(L·d),average 2.60 g/(L·d);volumetric biogas product of 0.5—2.85L/(L·d) could be achieved.
