The nitrogen loading rate (NLR) of an anammox attached film expanded bed (AAFEB) reactor was increased from 5.0 to 60.0 gN/L/d. During the stable operational period, the TN removal efficiency maintained at 87.3 ± 2.5%, and a maximum nitrogen removal rate (NRR) of 44.9 ± 0.3 gN/L/d was achieved. Overload resulted in the sharp deterioration of reactor performance, the ratio of (Food/Microorganism)/SAA should be maintained at lower than 66 ± 7% to ensure the stable operation of the AAFEB reactor. New stoichiometric equations for the anammox process under the low NLR condition (5.0 gN/L/d) and the high NLR condition (50.0 gN/L/d) were proposed. The quantitative SAA-cytochrome heme C relationship was established for the first time that providing a simple way for monitoring the reactor performance. Substrate tolerance ability was significantly increased that proving the stability of the AAFEB reactor was continuously enhanced during the stable operational periods.

厌氧吸附膜附着式薄膜膨胀床（AAFEB）反应器的氮气负载率（NLR）从5.0增​​加到60.0 gN / L / d。在稳定运行期间，总氮去除效率保持在87.3±2.5％，最大氮去除率（NRR）为44.9±0.3 gN / L / d。过载导致反应器性能急剧下降，（食品/微生物）/ SAA之比应保持低于66±7％，以确保AAFEB反应器的稳定运行。提出了在低NLR条件（5.0 gN / L / d）和高NLR条件（50.0 gN / L / d）下厌氧氨氧化过程的新化学计量方程。首次建立了定量的SAA-细胞色素血红素C关系，这为监测反应器性能提供了一种简单的方法。
