摘要采用静态箱和激光甲烷检测仪等设备开展了50组地表甲烷通量测试,分析了不同龄期垃圾堆体上部土质覆盖层的甲烷氧化能力,并修正了评估现场土质覆盖层甲烷氧化速率和甲烷氧化率的计算方法.结果表明:80%测试点的地表甲烷通量低于澳大利亚CFI(澳洲碳农业倡议)规定限值60g/(m²∙d),导气竖井附近20m范围内存在甲烷通量超过CFI规定的排放热点.填埋龄期3~7a堆体的地表甲烷通量从1.13g/(m²∙d)下降到0.53g/(m²∙d),7~10a的地表甲烷通量基本保持稳定.甲烷氧化速率和覆盖层底部甲烷通量具有正相关性,现场测得的土质覆盖层最高甲烷氧化速率为63.30g/(m²∙d),对应的底部甲烷通量为75.95g/(m²∙d).每一龄期堆体上部黄土覆盖层的平均甲烷氧化率均超过90%.

Abstract：50 sets of surface methane flux tests were conducted to test and analyze the methane oxidation capacity of the soil cover at different landfilling ages by using static chamber, laser methane detector and other equipment. In addition, a modified calculating method was proposed to directly evaluate the methane oxidation rate and methane oxidation fraction of the soil cover. The field test and analysis results indicated that the surface methane flux at 80% of the test sites were lower than the CFI (Carbon Farming Initiative) standard of 60g/(m²∙d); there were emission hotspots with methane flux exceeding CFI limit within 20m near the gas guide shaft. The surface methane flux of the landfill decreased from 1.13g/(m²∙d) to 0.53g/(m²∙d) during the landfilling ages from 3 to 7 years, and remained basically stable during the period of 7 to 10 years. There was a positive correlation between methane oxidation rate and methane flux at the bottom of the cover. The maximum methane oxidation rate measured in the soil cover was 63.30g/(m²∙d), and the corresponding methane flux at the bottom was 75.95g/(m²∙d). The average methane oxidation fraction of the upper loess cover at each landfilling age was over 90%.

Key words： municipal solid waste landfill landfilling age soil cover methane flux methane oxidation rate methane oxidation fraction
