摘　　要： 近几年来,好氧颗粒污泥的研究得到人们的广泛关注,但其研究规模主要局限于小试,还很少有工业应用的报道。回顾了好氧颗粒污泥的研究成果,分析了好氧颗粒污泥的形成机理及应用,并探讨了好氧颗粒污泥的特征及其颗粒化过程的主要影响因素。指出,好氧颗粒污泥是近期发现的在有氧条件下自发的细胞自固定化过程,是生物膜的特殊生长形式,具有良好的沉降性能、较高的生物量和生物活性。 The research on aerobic granulation has recently been given appropriate attention. Many studies are evaluated at the bench-scale in laboratory studies, there have been few reports on its industrial application. The results of fundamentals and applications of aerobic granulation are reviewed. And the characteristics and factors influencing on aerobic granules are discussed. It is found that aerobic granular sludge is self immobilized sludge and is a special case of biofilm. Aerobic granular sludge demonstrates high settling velocities resulting in good liquid separation, high biomass retention and good activity.
