摘　　要：综述了废水处理中厌氧污泥颗粒化研究进展，介绍了厌氧颗粒形成的主要理论，解释了颗粒污泥之间的关系、组成和厌氧污泥颗粒化的影响因素。研究表明：胞外聚合物是细菌群落以颗粒污泥形式存在关键；此外，温度、有机负荷率、pH值、碱度、营养盐、阳离子和重金属是影响厌氧颗粒污泥形成的重要因素。提出产甲烷过程中的产气量与颗粒污泥内部产甲烷菌的活性密切相关。Progress in research on the granulation of anaerobic sludge formed in the wastewater treatment process was reviewed, and main theories about the formation of anaerobic granules were presented to explain the granular sludge composition and influencing factors in the anaerobic sludge granulation. Extracellular polymer （ECP） was found totally responsible for the existence of microbe community in a form of granular sludge. In addition, dependable factors of anaerobic granule formation process including temperature, organic loading rate, pH value, alkalinity, nutrients, cations and heavy metals have been discussed. It was believed that the process of biogas production closely related to the activities of methanogens, which were practically found in the core of granules.
