摘　　要：近年来,好氧颗粒污泥技术凭借其优良的沉降性能以及较好的处理效果等优点,引起了人们越来越多的关注。通过参考大量的文献资料,简要总结了国内外学者关于颗粒污泥形成机制的多种假说与形成步骤,并从沉淀时间、水中金属离子、不同有机底物及负荷、水力剪切力和饱食-饥饿期几个方面分别讨论了各自对好氧颗粒污泥形成及稳定运行的影响。最后列举了好氧颗粒污泥在实际工程中的应用,目前仍存在的问题以及未来发展的方向。Nowadays the aerobic granular sludge technology has become more and more attractive to researchers for its excellent settling ability and treatment efficiency compared with traditional activated sludge. The formation mechanism and steps of ~terobic granular sludge was summarized by referring to a mass of domestic and overseas document literature, and the factors influencing the granules formation and stabilization were discussed, such as settling time, divalent ions, organic substrates and loading rate, hydraulic shear force and feast-famine time. At last, the applications of aerobic granular sludge technology in practical engineering were illustrated, and problems existing in current research and directions for future research of aerobic granular sludge were proposed.
