摘　　要：填埋是垃圾处理处置最常见的手段。随着生物反应器型填埋场的广泛应用,渗滤液回灌作为其中一项关键技术发挥着重要作用。渗滤液回灌在加速填埋场稳定化、加速填埋场沉降和提高产甲烷气量等方面具有关键作用。本文主要回顾了渗滤液回灌技术在垃圾填埋场中增大甲烷产量的研究历程,阐述了渗滤液回灌至垃圾填埋场可促进产甲烷的机理及影响因素。渗滤液回灌技术提高了甲烷产量,若是将甲烷气体加以收集利用,可减少化石燃料的燃烧,实现废物的资源再利用,从而得到较好的社会效益。Landfill is the most common means of waste disposal. With the wide application of bioreactor type landfills, leachate reinfusion plays an important role as one of the key technologies. Leachate recirculation has a key role in accelerating the stabilization of landfills, accelerating their sedimentation and increasing methanogenic gas production. This paper mainly reviews the research courses of leachate recirculation technology on augmenting methane production in landfills, and illustrates the mechanism and influencing factors of leachate recirculation to landfills to promote methane production. The methane production is improved by leachate recirculation technology. If the methane gas is collected and utilized, the combustion of fossil fuel can be reduced, and the resource reuse of waste can be realized, so as to obtain better social benefits.
