摘　　要：总结了颗粒有机物在厌氧消化过程中水解动力学的研究进展。颗粒有机物的水解动力学模型可以分为3类:基于颗粒有机物浓度的水解模型;基于颗粒表面积的水解模型以及基于颗粒有机物成分的水解模型。其中Yasui H模型首次提出颗粒有机物的各组分分别水解的概念,在实验过程中能较精确地反映产甲烷速率的变化,但其各组分的化学意义不明确,还需开展更深入细致的研究。Research progress on hydrolysis kinetics of particulate organic materials during anaerobic digestion process was summarized. The hydrolysis kinetic models of particulate organic materials can be classified into 3 types： concentrationrelated kinetics; surface-related kinetics and substance-related kinetics. The concept of different substances of particulate organic materials having different hydrolysis pathways was first proposed in Yasni H model while the model can accurately reflected variety of methane production rate. However, as chemical meaning of different substances of particulate organic materials was not revealed, the model still need to be further studied.
