垃圾填埋场产气速率模型研究

结合前人的工作,分段建立了产气速率模型。自配垃圾试样进行有机物降解实验,根据试样降解的化学反应方程式及实验期间试样的质量变化,得到试样的产气量,由此计算试样的产气速率,确定了模型参数。实验结果表明:试样在实验初期产气速率增加较快,达到产气高峰后逐渐降低。用建立的模型进行产气速率计算,计算结果与实测数据比较接近,说明本文建立的模型是可靠的。

Research on Gas Production Rate Model of Solid Waste in Refuse Landfills

Based on predecessors'studies,gas production rate model was established with partition.Experiments on organic matter degradation were made by using self-prepared solid waste specimens.According to the chemical reaction equation of specimen degradation and quality variation of specimens,gas production quantity was obtained,then gas production rate of the specimens was calculated,the parameters of model were finalized.It is indicated by the experimental results that gas production rate in the experimental initial period increased rapidly and then gradually decreased when it reached the gas production peak.The calculated result is close to the real data if gas production rate is calculated using the established model.It is certified that the model established in this paper is reliable.
