摘　　要：采用人工配置的生活垃圾,设计了不同污泥掺入量条件下的污泥-生活垃圾混合填埋试验,从污泥掺入量角度研究混合填埋体的降解规律,获得污泥-生活垃圾混合填埋体降解的动力学模型.研究结果表明:随着污泥掺入量的增加,有机质降解速率也越来越快,当污泥掺入量为30%时,混合填埋体的降解速率最快;生化降解稳定时间大致在2.55~5.76 a.Using artificially configured municipal solid waste,a sludge-municipal solid waste mixed landfill experiment was designed under different sludge mixing conditions,and the degradation law of the mixed landfill was studied from the perspective of the sludge mixing amount,and the kinetic model of the degradation of the mixed landfill was obtained.The research results showed that with the increase of sludge addition amount,the degradation rate of organic matter was increasing,indicating that the degradation rate of organic matter was getting faster.When the sludge addition amount was 30%,the degradation rate of mixed landfill was the fastest.The stabilization time of mixed landfill biochemical degradation was approximately 2.55-5.76 years.
