摘　　要：采用厌氧复合床,经自养型反硝化过程转化,成功启动了厌氧氨氧化反应器,共耗时165 d.反应器启动成功后,容积负荷达到了0.17 kg总氮/(m3·d),NO2-—N与NH4+—N去除率分别为100%和93.04%.稳定运行时,NH4+—N去除量、NO2-—N去除量与NO3-—N生成量之间的比值约为1∶1.18∶0.28.扫描电镜镜检发现,试验中的优势菌大小约为1,μm,呈圆形或椭圆形,成簇聚生,表面可观察到明显的漏斗状缺口,具有典型的厌氧氨氧化菌特征.The anaerobic ammonium oxidation （ ANAMMOX ） reactor in an upflow blanket filter （ UBF ）. The authors spent 165 days in successfully transited starting up. The ANAMMOX was from the autotrophic denitrification. After the start-up of the ANAMMOX reactor, the volumetric loading rate was up to 0.17 kg total nitrogen/（ m^3·d ） with the removal rate of 93.04%, for NH^＋4-N and 100%, for NO^-2-N, respectively. When operating at steady state, the molar ratio of NH^-4-N removal, NO^-2-N removal and NO^-3-N production was about 1 ： 1.18 ： 0.28. The scanning electron micrographs showed that the dominant bacterium was about 1μm in size, displayed circular or elliptical morphology, lived in cluster, and had crateriform nick on the surface. The character of the dominant bacterium was the same as that of typical ANAMMOX bacterium.
