摘　　要：阐述了以普通活性污泥和厌氧颗粒污泥为接种物时好氧颗粒污泥的形成过程,以及细胞表面较高的疏水性,基质中适当的Ca2+浓度,反应器内较高的水流剪切力和较短的沉降时间对这一过程的促进作用。Aerobic granular sludge is the active sludge with granular shape formed by inducing microbial self--agglomeration. In this paper, we summarized the formation of aerobic granular sludge by seeding active sludge and anaerobic granular sludge, respectively. The accelerating effects of high hydrophohicity of cell surface, moderate concentration of Ca^2＋ in the suhstrate, high shear force of stream and short settling time in the reactor of the process are also discussed.
