中文摘要	以4座有效垃圾量均为30t的模拟厌氧生物反应器填埋柱(R1~R4),每周分别回灌1.6,0.8,0.2m3的渗滤液和0.1m3清水,对比分析渗滤液回灌负荷对垃圾产气效能及稳定化进程的影响.结果表明,回灌比例最大(5.3%)的实验柱R1在回灌5周后开始大量产气,比R2~R4分别提前了7~13周;且垃圾产气速率与系统进水COD、VFA等污染负荷的变化存在正相关关系.回灌至第50周时,R1柱内垃圾更趋于稳定,TOC和COD的累积气相转化率分别为28.96%和14.57%,这表明部分有机质在回灌早期随液相流失,减少了垃圾产气潜能.因此,为提高生物反应器填埋场的垃圾产气效能,应根据垃圾稳定化的不同阶段适时地调整回灌方案.; Effects of leachate recirculation loading on the efficiency of aerogenesis or methanogenesis of municipal solid wastes(MSWs) was investigated in four simulated anaerobic bioreactors(R1～R4),which were filled with 30 tons of wet weight waste each and recirculated weekly with 1.6,0.8 and 0.2m~3 leachate and 0.1m~3 pure water,respectively.The results indicated that R1,with the highest recirculation ratio of 5.3%,began to produce landfill gas(LFG) largely after 5 weeks of leachate recirculation,while the other columns took 7～13 more weeks of lag phase time of LFG production.And LFG generation rates had good relationships with pollution loadings,such as COD and VFA in the leachate.By the 50th week,the waste in R1 was more stabilized with the highest loading rate.The accumulative transfer ratios to gas phase of TOC and COD were 28.96% and 14.57%, respectively,which meant large mount of organic matter was carried out by the effluent of the early stage and thus the potential of LFG generation was reduced.Therefore,to enhance the efficiency of LFG generation,the regimes of leachate recirculation in bioreactor landfills should be adjusted timely according to the phases of waste stabilization.; 深圳市科技局资助项目
