| 摘 要： | 以包裹无纺布的微孔炭管作为膜曝气生物膜反应器（MABR）的膜组件，进行了短程硝化，厌氧氨氧化和反硝化耦合脱氮(SNAD)研究。实验中，控制温度34±1℃，pH 7.5～8.5, HRT 8 h，通过逐步降低膜内压力使反应器中的溶解氧由8 mg/L逐步降低到0.5 mg/L以下。实验采用亚硝酸细菌挂膜，然后接种厌氧氨氧化细菌，实现在单一反应器中同时发生短程硝化、厌氧氨氧化和反硝化耦合脱氮功能。结果表明，经过180 d的连续稳定运行，氨氮去除率达到了93.4%，总氮去除率达到了92.5%，COD去除率达到97.2%, 氨氮去除负荷0.6 kg N/（m3 ·d）。适合SNAD工艺的最佳C/N比为0.2～0.6，当COD浓度过高时，会抑制厌氧氨氧化细菌，使SNAD工艺的处理效果明显下降。
