摘　　要：温室效应导致的全球变暖是备受瞩目的环境问题之一,其中垃圾填埋场产生填埋气是全球温室气体的重要来源。文章从垃圾填埋场的CH4产生、CH4减排技术和覆盖层CH4氧化行为及其影响因素等方面对国内外研究现状进行总结,为全面认识垃圾填埋场的CH4减排提供参考。目前,填埋场CH4减排技术包括填埋层原位减排、资源化利用和末端控制技术等,其中准好氧填埋技术和生物覆盖层甲烷氧化技术是适合我国现阶段大量中小型填埋场CH4减排要求的技术。填埋场覆盖层的特性如温度、含水率、有机质含量、pH值、孔隙率、CH4/O2比、植被和无机氮等都会影响其甲烷氧化能力,是填埋场覆盖层甲烷氧化能力研究和调控的主要参数。Greenhouse effect caused by global warming is one of high-profile environmental issues,and landfills gas produced by MSW landfills is an important source of global greenhouse gases.This paper reviewed research status about the landfill CH4 production,CH4 emission reduction technologies and cover CH4 oxidation behavior and its influencing factors,which can provide the full understanding for landfill CH4 emissions.Currently,the technologies of CH4 emission reduction in landfill include the in-situ reduction technology of landfill layer,resource utilization and end control technology.At the present stage,the semi-aerobic landfill technology and bio-methane oxidation by landfill cover was considered to de the most suitable CH4 emission reduction technologies for a large number of small and medium landfills in China.The characteristics of landfill cover,such as temperature,moisture content,organic matter content,pH,porosity,CH4/O2 ratio,vegetation and inorganic nitrogen,which will affect the methane oxidation capacity of landfill cover,were main parameters for CH4 oxidation researching and controlling.
