| 摘 要： | 采用ASBR(530 L)接种A~2/O厌氧污泥,考察了厌氧氨氧化(ANAMMOX)的启动及其与反硝化耦合处理含盐废水的脱氮特性,并对菌群结构进行了分析.结果表明,温度35℃±1℃、反应时间为14 h,160 d可实现ANAMMOX的成功启动.稳定运行阶段,ANAMMOX与反硝化耦合(SAD)使得总氮(TN)去除率和去除负荷分别达91.1%和0.45 kg·(m~3·d)~(-1);污泥呈浅红色颗粒状,厌氧氨氧化菌为优势菌,且主要菌属为Candidatus Brocadia(10.6%).此外,采用按梯度逐步提高盐度的驯化方式,可实现SAD对高盐(Cl-浓度8 000 mg·L-1)模拟火电厂废水的高效脱氮除碳,COD和TN去除率分别达93.2%和90.0%.推测SAD中反硝化主要为NO_3~--N→N_2,部分反硝化(NO_3~--N→NO_2~--N)仅占30.3%.
