本文比较分析了几种常用的有关垃圾场甲烷气产率计算方法,并详细计算了甲烷的产率及累计产量,在此基础上用一个比较实际的垃圾填埋场计算垃圾填埋过程中甲烷气的产率情况及累计产量,为垃圾填埋场的沼气发电提供了可靠的资料。并用此方法计算了全国各省份垃圾的甲烷排放量,并大致计算了全国的垃圾中甲烷资源的潜力。

In this study,we analyze several calculation methods of the production rate of methane in rubbish and make a detailed calculation of the production rate and the cumulate output of methane. On the basis of this study,we use a real rubbish dumping field to calculate the production rate and the cumulate output of methane. It helps to supply the useful reference deta for producing electricity from rubbish in the rubbish dumping fields. Finally we calculate the methane output from rubbish of every province and the potential methane resource in rubbish of the whole country.
