生活垃圾卫生填埋甲烷排放及减排研究进展

卫生填埋是生活垃圾最主要的处理方式，生活垃圾卫生填埋场产生甲烷(CH₄)等温室气体，加快全球气候变暖进程，引起各国政府的高度重视。笔者探讨了影响生活垃圾卫生填埋场CH₄产生的因素，对CH₄减排技术进行了总结。目前，生活垃圾卫生填埋场CH₄减排技术主要包括填埋层原位减排、资源化利用和末端控制技术等。为了控制和减少CH₄排放量，中国需要增加技术和设施投入，加强生活垃圾卫生填埋场气体排放的管理，开发有效的CH₄抑制技术，建立适合中国国情的CH₄等温室气体减排技术体系。

Methane Emission and Emission Reduction in Domestic Waste Sanitary Landfill

Sanitary landfill is the main way of domestic waste treatment, however, domestic waste sanitary landfill produces methane and other greenhouse gases, which speed up the process of global warming and draw great concern from governments. The authors discussed the influencing factors of methanogenesis of domestic waste sanitary landfill, and summarized the technology of emission reduction technology. At present, the methane emission reduction technology in domestic waste sanitary landfill mainly included landfill in situ reduction, recycling use and end control technology. In order to control and reduce the emission of methane, China should invest more in technology and facility, strengthen the management of domestic waste sanitary landfill gases, develop the effective technology of methane reduction, and establish the technical system of methane emission reduction and other greenhouse gas emission reduction according to China’s national condition.
