垃圾填埋场填埋气体产气量计算方法研究

Research on Calculation Methods of Landfill Gas Generation

垃圾填埋场在垃圾不断地被降解和稳定化的过程中将产生气体，垃圾填埋产气率预测对于评估填埋场能源气体产生潜力，确定填埋气体利用方式极为关键。为了更准确的计算填埋气体的产气量，以北方某生活垃圾填埋场为例，使用一阶降解模型、Monad模型和Schollcanyon模型，分别对填埋场的填埋气体产生量进行预测。结果表明，一阶降解模型是针对具体的垃圾填埋场，综合考虑了填埋场垃圾填埋量、垃圾组分等变化因素，能够较合理地对填埋场垃圾产气规律进行预测。

Landfill gas（LFG） will release from landfill in process of degradation and stabilization. Predicting LFG generation rate is very important to assess LFG resources and to determine the manner of LFG utiliza- tion. For a accurate calculation result, one--order degradation model, Monad model and Scholl canyon model have been used to predict the LFG generation situations for a northern landfill. Results show that one--order degradation model is set up for specific landfill. Considering of the landfill capacity and waste components, this model will get more reasonable result on LFG prediction.
