摘　　要：采用Chen-Hashimoto模型研究了不同进料基质浓度下,污泥中温两相厌氧消化小试工艺的动力学特性。根据两个投加不同来源剩余污泥的系统运行数据,表明基质II中存在抑制物质。添加厨余垃圾的系统动力学参数μmax和K值都高于未添加的两个系统,这表明添加厨余垃圾提高了厌氧消化工艺的产气性能,污泥与有机固体废物的联合厌氧消化效率要高于污泥单独消化。根据Chen-Hashimoto模型分别计算出小试系统的动力学参数值μmax和K,基质I、II和III的μmax值分别为0.177、0.146、0.209 d-1,K值分别为0.239、0.178和0.265。The Chen-Hashimoto model was used to examine the kinetic characteristics of mesophilic two-phase anaerobic digestion under different influent VS concentrations. According to the experimental data from two systems of different sludge sources, there existed some inhibitory matter in substrate Ⅱ. The kinetic parameters of μmax and K of substrate Ⅲ were both higher than the others, which suggested that the addition of kitchen garbage impoves the biogas production. The μmax values for three systems are 0.177, 0.146 and 0.209 d^-1 respectively, and the K values for three systems are 0.239, 0.178 and 0.265 respectively.
