摘　　要：以城市污水厂污泥为底物,结合两相厌氧消化的工艺研究,初步探讨了两相厌氧消化的机理。通过试验,估算了高温酸相以及传统一段法的动力学常数。试验结果还表明,两相法的有机物分解率优于传统一段法。This paper presents a study on the two-stage anaerobic digestion of sewerage sludge. In it,the kinetic parameters were estimated from the experimental data by using Monod model. The experimental result has shown that,the organism degradation efficiency of the two-stage system is higher than that of traditional single-stage system at same HRT. At the end,the mechanism of two-stage anaerobic digestion is discussed.
