Two typical estimation models were used to predicted LFG production rate in next 20 years. The prediction results were consistent with the current landfill gas production by testing report and the higher concentration of hydrogen sulfide was detected under the membrane. The result shows that membrane covering may improve LFG production and induced higher concentration of hydrogen sulfide under it. * Peng Lu, Qiguang Cao, Xiaohui Zhang* , Guoli Xie, Hongmei Chen, Linan Xing, Mingyue Zheng, Yuning Zhang, Song Li, Xiao Fu, Bioengineering Faculty of Beijing Electronic Science Technology Vocational College, Beijing 100029，China; Guiqin Wang, Xinyan Liu, Xu Zhang, Zongzheng Zhang, Beijing Environmental Sanitation Engineering Research Institute, Beijing 100028, China; Zhifeng Dai, Beijing Municipal Commission of City Administration and Environment, Beijing 100021，China Author biography: Peng Lu (1969-), Ph.D, The main research direct ion is the solid waste treatment, E-mail：lupeng531@163.com Responsible author: Xiaohui Zhang, Ph.D, The main research direct ion is the solid waste treatment, E-mail: zxh11218@ INTRODUCTION Landfill gas (LFG) mainly comprised of methane (the primary component of natural gas) and carbon dioxide that produce after municipal solid waste buried at landfill site. Methane is an important green house gas which has the effect 25 times compared to carbon dioxide [1]. LFG also contains variety of carcinogenic and odorous compounds that m
