中文摘要：

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℃，pH7．5～8．5，HRT8h，通过逐步降低膜内压力使反应器中的溶解氧由8mg／L逐步降低到0．5mg／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180d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0．6kgN／（m^3·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。

英文摘要：

A lab-scale membrane-aerated biofilm bioreactor （ MAtin） equipped, port around the gas-permeable carbon tube was developed for the removal of ammonium based on simultaneous partial nitrification, anaerobic ammonium oxidization and denitrification （SNAD）- The temperature, pH and HRT were controlled at 34 ＋ 1 ℃ , 7.5 - 8.5 and 8 h. By decreasing the air pressure in the carbon tube gradualreactor was decreased from 8 mg/L to 0.5 mg/L. Initially, the reactor was inoculated with nitrifly, DO in the SNAD system in one reactor. The reying biomass. Subsequently, anammox biomass was inoculated to start up sults showed that after 180 d of operation, 93.4 % of NH4^＋-N removal rate, 92.5 % of TN removal rate and 97.2 % of COD removal were achieved in MABR. The ammonium nitrogen removal rate was 0.6 kg N/（m^3 d）. The suitable C/N ratio is 0.2 - 0.6, and the higher COD will inhibit the Anammox bacteria and make the reactor performance worsen.
