城市生活垃圾填埋场填埋气体收集导排工程设计探讨

Discuss on the Design of MSW Landfill Gas Collection Project

填埋气体是城市生活垃圾填埋场产生的一种主要污染物和易爆危险物，同时它也是一种能源。因此对填埋气体进行有效地收集和导排，不仅可有效防止填埋气体对周围环境的污染、避免爆炸事故发生，而且还可以利用其能源获得一定经济效益。本文从工程实际的角度探讨了填埋气体的计算方法和工程设计方法，提出了填埋气体收集利用工程设计中应考虑的一些问题。

Landfill gas （LFG）is a kind of pollutant and dangerous gas from a MSW landfill. And LFG is also a kind of energy. Effectively leaded, collected and used, the landfill gas can not only avoid polluting and exploding, but also get benefit from gas utilization. The way of calculating LFG quantity and engineering design of collecting facilities will be discussed in this paper. Some suggestions and conclusions that should be considered on design are submitted.
