垃圾填埋气收集利用全流程系统解决方案

The Whole Process Systematic Solution for Collection and Utilization of Refuse Landfill Gas

垃圾填埋气的收集利用是一项对环境有益且经济可行的技术手段。我国目前的垃圾填埋气处理模式存在收集效率低下、资源化利用水平低、产业化发展不足等问题,严重制约着我国实现垃圾填埋气资源化、无害化的目标。在统筹安排、协调统一温室气体减排问题与垃圾填埋气高值利用问题的前提下,针对处于填埋作业中和填埋封场后等不同阶段的填埋场,以我国多处典型垃圾填埋场为实际案例,阐述垃圾填埋气高效收集系统、以变压吸附过程为基础的填埋气甲烷高效分离技术、集成化撬装式垃圾填埋气甲烷分离提纯装备的探索、优化、推广过程;在此基础上,提出"高效收集-净化提纯预处理-资源化利用"的全流程系统解决方案,以期对垃圾填埋气高效收集利用的各个流程环节提供技术支撑。

The technology of collection and utilization of refuse landfill gas is cost effective and environmental friendly.The current treating model of landfill gas,with low collection efficiency and utilization,and insufficient industrial development,is still the major restricting factor on the objective of landfill gas utilization.On the premise of overall coordination between greenhouse gas emission control and landfill gas utilization,aimed at different stages of refuse landfills,this paper discussed the efficient collection,methane separation based on pressure swing adsorption,and landfill gas upgrading equipment,with several typical landfills in China as the actual cases.The whole process systematic solution of efficient collection-purification and upgrading-resource utilization was proposed,which would provide technological support for refuse landfill gas collection and utilization.
