| 摘 要： | 以低C/N值生活污水为处理对象,重点考察了以厌氧/缺氧(A/A)运行的ABR耦合好氧MBR系统启动过程中脱氮除磷特性及系统长期运行的稳定性.结果表明,控制ABR容积负荷(VLR)为0. 8 kg·(m3·d)-1,污泥回流比为80%,硝化液回流比从150%逐步提升稳定至300%,反硝化除磷功能区污泥停留时间(sludge retention time,SRT)为25 d,MBR溶解氧(DO)为1～2 mg·L~(-1),温度为30℃±2℃,于46 d成功富集了反硝化聚磷菌(denitrifying phosphorus bacteria,DPBs),净释磷量为20. 56 mg·L~(-1),净吸磷量达到27. 74 mg·L~(-1),批次实验表明约84. 8%的聚磷菌(PAOs)能够利用NO-3-N作为电子受体进行反硝化除磷.启动成功后稳定运行50 d,对COD、NH+4-N、TN和PO_4~(3-)-P的平均去除率分别为91. 8%、99. 0%、71. 5%和94. 2%,系统缺氧反硝化除磷去除1 mg·L~(-1)的PO_4~(3-)-P,同步消耗约0. 83 mg·L~(-1)的NO-3-N,满足同步脱氮除磷的要求.
