摘　　要：本论文分别对初沉污泥、生化污泥及深度处理污泥的基本物化性质及热解特性进行了研究,并进一步采用Coats-Redfern法描述了热解过程,计算了三种污泥的热解动力学参数。动力学研究结果表明:造纸厂水处理初沉污泥有机物热解主要区域的反应级数为2,二沉污泥及深度处理污泥的反应级数为3,三者的活化能分别为:43.80kJ/mol、32.74kJ/mol及17.16kJ/mol,频率因子分别为:1.56×106min-1、1.18×107min-1、2.60×108min-1。Basic properties and pyrolysis characteristics of primary sludge, secondary sludge and advanced treatment sludge from paper mill were studied. According to the analysis of pyrolysis process by means of Coats-Redfern method and based on the calculated kinetic parameters of three kinds of sludge at 10℃/min heating rate. It is found that the reaction order of primary sludge is 2 at the organic pyrolysis region, the other two are 3. The activation energy of the three kinds of sludge are 43.80 kJ/mol, 32.74kJ/moland17.16kJ/mol, and their frequency factor are 1.56×10^6min-1, 1.18×10^7min-I and 2.60×10^8min-1 respectively.
