摘　　要：污泥中的微生物能够将其中的有机物降解,影响污泥的填埋工程应用。针对这种问题对污泥开展降解试验,分析污泥中的有机物的降解过程,并总结出污泥有机物降解的降解规律和动力学模型。结果表明:污泥中有机物含量整体趋势是随着时间逐渐减小;有机物降解速率在初期波动较大,但整体趋势依然是随着时间逐渐减小;随着降解时间的增加,污泥的p H先是降低,然后慢慢回升,继而逐渐趋于稳定;而污泥的含水率逐渐增加。有机物降解的动力学模型适合指数关系(M=M_0e^(-βt))。Engineering application of sludge landfill might be influenced because of organic degradation from micro-organic activities. A study on the law of organic matter degradation was conducted to obtain the dynamic model. Results showed that the whole trend of organic matter content was gradually decreased with time in sludge. The degradation rate of organic matter in the early stage was fluctuant,but the overall trend was still gradually decreased. With the increase of degradation time,the PH of the sludge was reduced,then slowly rebound,and gradually stabilized. The water content of sludge was gradually decreased. Dynamic model for the degradation of organic matter fit the exponential relationship M= M0e^-βt.
