摘　　要：根据重庆市生活垃圾的组成特点,自配垃圾试样进行有机物降解实验,根据实验期间试样的质量变化,结合降解反应方程式,计算试样的产气量,并建立产气率模型。实验结果表明,试样质量随时间逐渐降低,呈指数型衰减规律。试样在实验初期产气率增加较快,达到产气高峰后逐渐降低。用建立的产气率模型进行计算,计算结果与实测数据比较接近,说明该产气率模型是可靠的。According to the component characters of the municipal solid waste（MSW）in Chongqing,the MSW sample was confected and the organic matter degradation test was carried out.In terms of the weight change to calculate the landfill gas production and build the generation rate model with the degradation reaction.The results show that the weight decreases along with the time,through the data fitting,the weight change presents trend of exponential attenuation.The gas production rate increases rapidly in the initial stage,when it reaches the peak value,the rate decreases gradually.Using the model to calculate the gas production rate,the results approximate with real data,this shows that the model is credible.
