我国填埋场改造及发展方向的探讨

Discussion on Landfill Improvement and the Way to Develop in China

对我国部分生活垃圾填埋场和室内填埋设施的填埋气组分进行了现场测试和分析 ,结果表明 ,厌氧填埋场的CH4 含量高 ,半好氧填埋场CH4 含量很低。并针对我国填埋场的现状提出了如果打算利用填埋气进行发电 ,填埋构造可以作成厌氧填埋 ,否则 ,填埋场应以安全性为主 ,应建造成半好氧结构。

The generation situation of LFG was monitored and analyzed in some of laboratory installations and landfill sites.It is indicated that CH 4 content is high in anaerobic landfills and very low in semi\|aerobic landfills.And based on the relevant literature search for the status of landfills in China,this paper discussed the way to develop in the future.Landfill type should be anaerobic type if LFG resource is planned to generate electricity,otherwise it should be safe type in prioity,namely semi\|aerobic type.
