摘　　要：针对我国高厨余垃圾填埋后降解和填埋气产生速度快的特点,提出了填埋气高效收集方法,包括源头密闭、集气设施、集气管网、引风设施、预处理设施和利用设施等6个环节的技术措施,各项技术措施的处理能力均需要与理论产气量匹配。通过在深圳市下坪填埋场的应用实践表明:填埋气收集量从2014年的6413 m^(3)/h上升至2019年的45500 m^(3)/h,填埋气收集率从23%提升至94%,实现了填埋气的高效收集,减少了无序逸散造成的环境问题。In view of the characteristics of high kitchen waste degradation and fast landfill gas generation in China,an efficient landfill gas collection method was proposed,including six technical measures,such as source containment,gas collection facilities,gas collection pipe network,air extraction facilities,pretreatment facilities and utilization facilities,and the processing capacity of each technical measure should match the theoretical gas production.The application was carried out in Xiaping landfill in Shenzhen,and it showed that the landfill gas collection volume increased from 6413 m^(3)/h in 2014 to 45500 m^(3)/h in 2019,and the landfill gas collection rate increased from 23%to 94%,which realized the efficient collection of landfill gas and reduced the environmental problems caused by disorderly escape.
