垃圾填埋气产生量估算模型简述

摘要

目前国内生活垃圾的主要处理方式是卫生填埋,填埋气中甲烷的成分占40%～60%,可作为一种清洁的可再生能源加以利用。利用填埋气首先确定其产生速率和产生量,建立准确预测填埋气产气量、产气周期、产气速率的估算模型非常重要。本文论述计算甲烷气体产生量和产气速率模型（动力学模型、统计学模型与经验模型）的使用条件和优缺点。不同的模型有不同的使用条件,目前使用较多的是经验模型。应用国外成熟模型对北京市填埋场进行填埋气估算,需要调整模型中相关参数,关键参数的确定需要实验数据作支撑。%Landfill is the most important municipal solid waste treatment technology nowadays.Landfill gas with methane of 40%~60% is a kind of clean and renewable energy.The estimation of landfill gas generation rate and quantity as well as the models which forecast gas generation accurately are necessary for landfill management.This paper reviews the advantage,disadvantage and applicability of theoretical models（dynamic models and statistics models）and empirical models,which is commonly used in the developed countries.Current models can be used for landfill gas generation in Beijing after parameters adjustment on the basis of experimental data.
