Abstract 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.
