摘　　要： 从好氧颗粒污泥的基本性质,相对于普通活性污泥的优势、好氧颗粒污泥形成的机理以及在污水处理中的应用等四个方面,综述了国内外好氧颗粒污泥的研究成果。好氧颗粒污泥是近几年发现的在好氧条件下自发形成的细胞自身固定化颗粒,具有良好的沉淀性能、较高的生物量和在高容积负荷条件下降解高浓度有机废水的良好生物活性。好氧颗粒化过程是一个多阶段的过程,取决于废水组成、操作条件和接种污泥等因素。由于其特殊的内部结构和生物相,同时好氧颗粒污泥也是一种良好的重金属吸咐剂。 The latest research works on aerobic granular sludge were reviewed , which covered the sludge general properties, the advantage relative to conventional activated sludge, formation mechanism as well as its application in wastewater treatment. Aerobic granular sludge is the self-immobilized sludge, which is recently found under the aerobic condition. Aerobic granular sludge demonstrates high setting velocities leading to good solid liquid separation,high biomass retention, high activity and an ability to withstand high loading rates. Aerobic granulation is a multiple phase process,which is depending on the composition of the wastewater, the operation condition and the seed suldge. Because of the special inner structure and microbial morphology, aerobic granular sludge also has ability to adsorb heavy metals.
