生活垃圾填埋产沼的提取净化利用

Distilling and Purifying Utilization on Biogas Generated from Domestic Refuse Landfill

垃圾填埋是目前我国各城市广为采用的垃圾处理方式,但垃圾填埋产沼以后对沼气的回收利用却不被人们所熟知和重视。由此造成了对可开发利用的二次能源的极大浪费,而沼气对周围环境也造成了严重的污染并对大气臭氧层造成了破坏。本文阐述了垃圾填埋产沼回收的必要性和经济性,对垃圾填埋产沼提取利用、制取汽车压缩气的可行性及工艺流程进行了分析和介绍。

Refuse landfill is one of refuse treatment methods which are applied widely in the cities, but people don＇t know and don＇t pay more attention to the recovery and utilization of biogas generated from refuse landfill that causes a great extravagant in the utilization of secondary energy. At the same time, biogas causes severe pollution to environment and damage to atmospheric ozone layer. The article explicates the necessity and economic benefits in utilizing biogas generated from refuse landfill; makes analysis and introduction in distilling and utilizing biogas generated from refuse landfill, and feasibility on getting auto compressed air as well as technology process.
