基于LandGEM模型估算北京六里屯垃圾填埋场填埋气的产气量及分析

Estimation of Gas Production and Analysis of Landfill Gas in Beijing Liulitun Landfill by LandGEM Model

对北京市六里屯垃圾填埋场的工程概况、历年垃圾填埋量、填埋气收集系统现状和垃圾量等做了研究。选用推荐的模型参数,利用LandGEM模型对六里屯垃圾填埋场2000—2045年填埋气体的产生量进行了估算。结果表明:采用推荐参数、应用LandGEM模型估算的结果较为准确;填埋气产气量在2016年达到最高峰。对收集率偏低的原因进行了分析,并总结提高填埋气收集率的要点。

We studied the project of Liulitun landfill in Beijing,landfill volume over the years,landfill gas collection system and waste volume. We adopted the recommended model parameters and used LandGEM model to predict the landfill gas production in Liulitun landfill from 2000 to 2045. The results showed that the estimated data using LandGEM model were more accurate with the recommended parameters. The production of landfill gas reached its peak in 2016. The reasons for the low collection rate were analyzed and the main points to improve the collection rate of landfill gas were summarized.
