Abstract

Abstract:

The research on the formation mechanism of aerobic granular sludge shows that the joint action of waterpower force，EPS and microorganism self-immobilization，etc. plays the key role，but at present，there has not been afinal conclusion. The basic characteristics is introduced，and the hypotheses about the formation mechanisms，suchas current main crystal nuclei，selective pressure driving，cell surface hypophobicity，EPS，self-agglomerative princi-ple，hyphomycete，and stage formation，etc. are summarized.

Key words: aerobic granular sludge, biological treatment, wastewater treatment

摘要：

介绍了好氧颗粒污泥的基本特性,并对目前主流的好氧颗粒形成机理如晶核假说、选择压驱动假说、细胞表面疏水性假说、胞外多聚物假说、自凝聚原理、丝状菌假说和阶段形成假说等进行了综述,结果表明,虽然目前还没有统一的机理,但水力剪切力、胞外多聚物、微生物的自固定等的联合作用对好氧颗粒污泥的形成起了关键作用。
