The effects of different operating conditions(AAO/inverted AAO,nitrification reflux ratio,hydraulic residence time)on nitrogen and phosphorus removal in a continuous flow aerobic granular sludge reactor were studied in order to provide conditions for the control of the continuous flow aerobic granular sludge reactor.The results show that there are two kinds of denitrification and denitrification and phosphorus removal for TN removal under AAO process.In the inverted AAO process,the lack of NO3--N as electron acceptor in the anoxic section inhibited the process of denitrification phosphorus removal.The increase of the reflux ratio and the prolongation of the hydraulic residence time of nitration are beneficial to the removal of TN.
