摘　　要：为揭示生活垃圾在填埋场条件下的厌氧降解规律,该文试验研究了生活垃圾中4种常见的有机组分:蛋白质、淀粉、脂肪和纤维素在厌氧填埋条件下的降解特性,并建立了动力学模型。研究揭示了单组分垃圾在填埋场中的降解动力学规律,为模型参数的确定提供了必要的数据。通过混合物料降解试验验证模型的可靠性,结果表明,试验值与模拟值吻合得很好。The components in the municipal solid wastes are the key factor for determining the stabilization of landfills. This paper presents experimental research and a dynamic model of single material （protein, amylum, fat, and cellulose） digestion for landfill conditions. The model describes the dynamics of single material digestion in landfills based on a mass balance and the Monod model for gas generation regulation of cellulose digestion in landfills. The model coefficients are based on test data. Mixed materials tests show that the models can predict the digestion rates of a range of materials.
