我国垃圾填埋场填埋气体排放和回收利用现状分析

城市生活垃圾填埋气体的回收和资源化利用是一项经济可行且对环境有益的技术。本文介绍了我国目前垃圾填埋气体产生、排放及利用情况,分析了几种填埋气体利用技术的特点及其在我国的适用性,并提出了未来我国城市生活垃圾处理的主要方向,即建立配备填埋气体回收装置的卫生填埋场。

The technology of recovery and utilization of landfill gas (LFG) from municipal solid waste (MSW) landfill sites is cost effective and environment friendly. In this article, the status of output, emission and utilization of LFG is introduced. The characteristics of several technologies of LFG utilization and their applicability for China are also analyzed. It is proposed that the future trend of MSW disposal in China is to develop and build the sanitary landfill sites installed the facilities of LFG recovery.
