摘　　要：针对好氧颗粒污泥颗粒化时间慢等问题,进行了同步硝化内源反硝化除磷好氧颗粒污泥常温储存及活性恢复实验研究.结果表明,好氧颗粒污泥经过60d的常温储存后,颗粒的结构基本能保持稳定,但是颗粒污泥的活性大幅度降低,污染物去除率仅有储存前的30%~40%.将常温储存的颗粒污泥接种到反应器中,经过一定的调控手段,可以在60d内恢复好氧颗粒污泥的功能及活性.此外,经过储存与恢复,好氧颗粒污泥的群落结构也发生了明显变化.大部分的微生物的相对丰度变化可逆,经过储存和恢复可以恢复至储存前的状态(包括Defluviicoccus(GAOs)和Flavobacterium(PAOs)),重构同步脱氮除磷的微生物群落结构.Aiming at the slow granulation time of aerobic granular sludge,an experimental study was carried out on the ambient storage and activity recovery of simultaneous nitrification and endogenous denitrification for phosphorus removal aerobic granular sludge.The results showed that after 60days of ambient storage of aerobic granular sludge,the structure of granular sludge was basically stabilized,but the activity of granular sludge was greatly reduced,and the pollutant removal rate was only 30%~40% of that before storage.The function and activity of aerobic granular sludge could be restored within 60days after certain control measures by inoculating the stored granular sludge into the reactor.In addition,the community structure of aerobic granular sludge changed significantly after storage and recovery.Most of the microorganisms had reversible changes in their relative abundance and could be restored to the pre-storage state after storage and recovery(including Defluviicoccus(GAOs)and Flavobacterium(PAOs)),which reconstructed the microbial community structure for simultaneous nitrogen and phosphorus removal.
