【摘要】 本文重点介绍了城市垃圾填埋场CH4 产生模型的研究成果 ,并以此为基础 ,对今后 2 0年我国垃圾填埋场CH4 产生情况进行了预测 ,预测结果表明 ,随着垃圾产生量的增长 ,CH4 排放量占我国温室气体排放总量的分额将从 2 0 0 0年的 3 83% ,增加到 2 0 2 0年的 7 19% ,其对温室效应的贡献不可忽视 ,对填埋场CH4 的控制和利用已成为我国城市垃圾管理领域的重要课题更多还原

【Abstract】 In order to control the total emission of methane efficiently,different models of methane generation from landfills were analyzed in this paper.The mathematical model of methane generation from landfills of the next 20 years in China is described.The results indicate that with the increasing of Municipal Solid Waste(MSW)landfilled,the fraction of methane from landfills in GHGs emitted in China would increase from 3.83%(in 2000)to 7.19?%(in 2020).Therefore its contribution to global warming can’t be ignored.The emission control and resource exploitation of landfill methane have the important tasks in MSW management.更多还原
