摘　　要：好氧颗粒污泥具有沉降性能良好、微生物群落丰度和多样性高、耐冲击负荷能力强等优点,在高有机负荷难降解废水、含重金属以及有毒有害工业废水领域中有广泛应用前景。但目前好氧颗粒污泥的培养和应用仍存在一些问题,如颗粒形成速度慢,培养条件苛刻,操作复杂、颗粒污泥的形成机制不明确,成熟颗粒污泥结构不稳定易解体等,这些问题很大程度上限制了好氧颗粒污泥的工业化推广。通过对好氧颗粒污泥形成机理、影响因素、快速培养及稳定性研究进行综合阐述,提出好氧颗粒污泥的稳定培养方法及研究方向。There are many advantages of aerobic granular sludge(AGS)including good settleability,high microbial community abundance and diversity,strong impact load resistance,etc.It has broad application prospects in treating toxic and harmful industrial wastewater as well as sewage of high organic waste and heavy mental.At present,problems are still existing in the cultivation and application of aerobic granules sludge such as slow formation rate,harsh cultivation conditions,complex operation condition,unclear formation mechanism,unstable structure and easy disintegration,which largely limit the industrialization of aerobic granular sludge.This study comprehensively expounds the formation mechanism,influencing factors,rapid cultivation and stability research of aerobic granular sludge,then puts forward the stable cultivation method and research direction of aerobic granular sludge.
