摘　　要：好氧颗粒污泥技术是近几十年来发展起来的一种新型微生物自固定化技术,通过特定的培育手段可以实现污泥颗粒化。这种颗粒污泥具有生物密度大、沉降性好、抗冲击能力强等优点,有的还具有优良的脱氮除磷等功能。简要介绍了SBR反应器中好氧颗粒污泥的沉降动力学模型,详细说明了其理化及生物学特性,并着重分析了好氧颗粒污泥脱氮功能的影响因素,提出了对好氧颗粒污泥脱氮进行深入研究的方向。Aerobic granular sludge （AGS） technology is a new microbiology self-immobilization technology which has progressed in the recent decades. The granulation can be achieved through special cultivation. This kind of granular sludge has high microbial density, good settleability and stronger resistance to shock loading. Some of AGS also have good capacity to remove nitrogen and phosphorus. The settling model of the AGS in SBR is introduced, its physicochemical and biological characteristics are described, the factors affecting the N-removal function of AGS are analyzed, and the further study trend of the nitrogen removal with AGS is put forward.
