摘　　要：硝化菌的生长快于厌氧氨氧化菌,通过培育硝化生物膜,利用硝化菌的基质多样性和代谢多样性,可使生物膜由催化硝化反应过渡到催化厌氧氨氧化反应,加速ANAMMOX反应器的启动。经过2个月的运行,成功地启动了ANAMMOX反应器,而且反应器运行性能稳定。将厌氧氨氧化引入反硝化聚磷系统中,试验结果表明,在COD和TP的去除率保持基本不变的情况下,NH4+-N的去除率从23%上升到87%,TN的去除率从88%提高到93%,出水NH4+-N和NO2--N的质量浓度均低于2mg/L。As nitrobacteria grew faster than anaerobic ammonia oxidation bacteria, through nurturing nitrification biofilm, with the effects of the substrate diversity and metabolic diversity of the nitrobacteria, the biofilm was transitioned from catalytic nitrification reaction to catalytic anaerobic ammonia oxidation reaction, which accelerated the start up of the ANAMMOX reactor. After 2 months of operation, ANAMMOX reactor was successfully started up, and the running performance was stable. The results of the test that inducting ANAMMOX into denitrifying phosphorus removal system showed that, under the condition that COD and TP removal rate holding constant, the removal rate of NH4^＋-N increased from 23% to 87%, the removal rate of TN increased from 88% to 93%, and the mass concentration of NH4^＋-N and NO2^--N in effluent water were below 2 mg/L .
