摘　　要：研究了在连续流好氧颗粒污泥反应器中,不同运行条件(AAO/倒置AAO、硝化液回流比、水力停留时间)对脱氮除磷的影响,以期为连续流好氧颗粒污泥反应器的控制提供条件。结果表明,在AAO工艺下,TN的去除存在反硝化脱氮和反硝化除磷两种方式;倒置AAO工艺下,缺氧段缺少NO_(3)^(-)-N作为电子受体,抑制了反硝化除磷方式的进程。硝化液回流比的增大和水力停留时间的延长有利于TN的去除。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 NO_(3)^(-)-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.
