摘　　要：在EGSB反应器中快速启动厌氧氨氧化(ANAMMOX)工艺,总氮去除速率为0.931±0.006 kg/(m^3·d),总氮去除效率为90.5%±0.8%。培养得到厌氧氨氧化颗粒污泥和絮状污泥混合物,污泥平均粒径为307.5μm。高质量浓度的NO_2^-(143.25 mg/L)抑制厌氧氨氧化菌活性;N_2H_4可强化厌氧氨氧化,但高质量浓度的N_2H_4抑制厌氧氨氧化菌活性;短期添加丙酸盐(COD质量浓度0~400 mg/L)对厌氧氨氧化速率几乎无影响;厌氧氨氧化速率随Fe^(3+)浓度(0~1.2 mmol/L)的增加而增加。ANAMMOX process is rapidly started- up in EGSB reactor,and the total nitrogen removal rate and the total nitrogen removal efficiency can reached 0. 931 ± 0. 006 kg/（m^3·d） and 90. 5% ±0. 8%. Granular biomass and floccular biomass are both found in reactor,and the mean radius is 307. 5 μm. High concentration of NO2^-（ 143.25 mg/L） inhibites the activity of ANAMMOX bacteria. The addition of N2H4 can enhance the performance of ANAMMOX,while the excess of N2H4 will inhibit the activity. The addition of propionate（ COD 0 ～ 400 mg / L） in short term has little effect on the rate of anaerobic ammonium oxidation,while Fe^3＋（0 ～1.2 mmol/L） can accelerate ANAMMOX process.
