摘　　要：好氧颗粒污泥因其具有较高的微生物量,具备脱氮除磷能力和良好的沉淀性能,在工业废水和城市污水处理中的应用潜力很大,但在其形成机理方面还存在问题并未彻底弄清。分析了好氧颗粒污泥的特点及其形成过程的影响因素,如胞外聚合物、水力剪切力、温度等;归纳了关于好氧颗粒污泥的形成假说,总结了其在城市污水和工业废水处理方面的应用情况以及好氧颗粒污泥稳定性及形成机理方面存在的问题,论述了好氧颗粒污泥技术今后的发展趋势。Aerobic granular sludge has great potential for application in industrial wastewater and urban sewage owing to its high microbial biomass,nitrogen and phosphorus removal capacity and good sedimentation performance. However, its formation mechanism has not been fully clarified. This paper analyzed the characteristics of aerobic granular sludge and the influencing factors of its formation process,such as extracellular polymeric substance,hydraulic shear force,and temperature. The formation hypothesis of aerobic granular sludge was summarized. Meanwhile, this paper studied its application in municipal wastewater and industrial wastewater treatment and the stability and formation mechanism of aerobic granular sludge. Finally, the development trend of aerobic granular sludge technology was discussed.
