• 摘要：采用厌氧氨氧化工艺(ANAMMOX)处理味精废水,结果显示,总氮容积去除负荷可达457mg·L^-1·d^-1,高于传统硝化-反硝化工艺,可成为传统硝化-反硝化工艺的替代技术.厌氧氨氧化菌对NO₂^--N的耐受范围为96.5～129mg·L^-1.受基质NO₂^--N抑制后,厌氧氨氧化反应器难以自行恢复,将基质浓度稀释到临界浓度以下则可恢复效能.反应器对进水c_NO2^--N/c_NH4⁺-N比值有一定的适应能力.在所试的进水c_NO2^--N/c_NH4⁺-N比值(1.0～1.4)范围内,出水基质浓度基本保持不变.

• Abstract：Physical and chemical treatment of industrial wastewater containing high concentrations of monosodium glutamate (MSG) is neither economical nor effective. Anaerobic Ammonium Oxidation (ANAMMOX) is a practical biological process that has been developed recently and has found wide application. Strong monosodium glutamate industrial wastewater containning high ammonia was treated with the ANAMMOX process. The total nitrogen removal rate was up to 457 mg·L^-1·d^-1, which was higher than that achieved with the traditional nitrification-denitrification process. The nitrite concentration tolerated by ANAMMOX bacteria was in the range of 96.5～129 mg·L^-1. However, tie reactor could not recover itself after complete inhibition by nitrite. Reducing the substrate concentration to the critical value could relieve nitrite inhibition. The ANAMMOX reactor showed some adaptability to the influent c_NO2^--N/c_NH4⁺-Nratio. The effluent substrate concentration remained relatively constant when the influent c_NO2^--N/c_NH4⁺-Nratio was in the range of 1.0 ～1.4.
