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。

关 键 词:炭管膜曝气生物膜反应器  短程硝化  厌氧氨氧化  反硝化
