填埋场甲烷排放因素分析及甲烷减排研究进展

Methane emission factor analysis and methane emission reduction research in landfill:A review

垃圾填埋场甲烷排放是全球人为温室气体排放的重要来源,对于整个大气中温室气体增加引起的气候效应的影响不容忽视,是世界各国现代化进程中迫切需要解决的一个严重的社会公害问题.文章从填埋场甲烷产生的相关因素、垃圾处理现状和填埋场甲烷减排技术等方面对国内外研究现状做了总结.甲烷的产生受填埋场中的垃圾特性、含水率、温度、pH值、填埋时间、渗滤液含量和其他因素影响.当前的填埋场减排技术包括原位减排、资源化利用和末端控制等,填埋场可以从多方面共同作用实现减排目标.

Landfill methane emission is an important source of anthropogenic greenhouse gases. Its influence on the increasing global greenhouse gas emissions in the entire atmosphere which cause climate effects can not be ignored and it is a serious problem of public nuisance that needs to be solved urgently in the modernization process of the world. The paper summarizes the related formative factors of methane, the present status of waste disposal and meth- ane emission reduction technologies at home and abroad. Methane production is affected by waste characteristics, moisture content, temperature, pH, time, leachate levels and other factors in landfill. The current landfill methane e- mission reduction technologies include the in situ reduction technique,resource utilization and end control technolo- gy. The landfill can achieve the goal of methane emission reduction from the combined effect of various aspects.
