摘　　要：垃圾焚烧场的渗滤液具有pH低、污染成分复杂、COD_(Cr)浓度高、可生化性好等特点。本研究探索了UASB法处理焚烧场渗滤液时的快速启动方法,考察了水力停留时间、容积负荷对COD_(Cr)去除率的影响及产气量与COD_(Cr)去除率的关系,结果表明,在水力停留时间6d、容积负荷5kg/(m3.d)的情况下,COD_(Cr)去除率可达到93%,每升原水产气量可达22.5L,折合热值492.7kJ。Leachate from solid waste store-tank in municipal solid waste incinerators factory has the character of high organic contamination and low pH.The start-up performance of commercial-scale UASB reactors to treat leachate at ambient temperature was investigated.The experiment was also designed to investigate the effects of COD_(Cr) degrading efficient on HRT and VLD.The results indicate that at a HRT of 6 d and the VLD of 5 kg/(m 3 ·d),the COD_ Cr degrading efficiency is above 85%,and the gas produced from the organic contamination of each raw leachate is 22.5 L.
