The impacts of transient overloads on the performance of a laboratory-scale anaerobic ammonium oxidation (ANAMMOX) anaerobic baffled reactor was studied by increasing the substrate concentration or inflow rate to 1.5-3.0 times above normal values. These shocks, with the exception of the highest substrate shock, weakened the nitrogen removal efficiency (NRE) but improved the nitrogen removal rate by 0.01-0.18 g l(-1) h(-1). The communities and the location of the sludge may be altered by distinct types of shocks. The substrate vibration data showed that the reactor was unresponsive to hydraulic shocks but sensitive to substrate shocks and the former compartments were more susceptible to the shocks. In the inhibition period, the pH and NRE of the reactor were related to the residual ammonium and free ammonia (FA) and FA was a factor in the reactor fluctuations. The Gaussian model proposed to describe the shocks response fits the experimental data well.
研究了通过将底物浓度或流速提高到正常水平的 1.5-3.0 倍来研究瞬态过载对实验室规模厌氧氨氧化（ANAMMOX）厌氧折流反应器性能的影响。这些冲击（除了最高的底物冲击）削弱了氮去除效率（NRE），但提高了 0.01-0.18 g l(-1) h(-1)的氮去除率。不同类型的冲击可能会改变群落和污泥的位置。底物振动数据表明，反应器对水力冲击不敏感，但对底物冲击敏感，前隔室更容易受到冲击。在抑制期，反应器的 pH 值和 NRE 与剩余氨和游离氨（FA）有关，FA 是反应器波动的一个因素。提出的高斯模型很好地描述了冲击响应，与实验数据吻合较好。
