摘要厌氧氨氧化系统在实际应用中会受到基质浓度波动、水力负荷增大和重金属元素的单独或联合效应影响 。因此，为了解这种系统的稳定性和应变性，用上流式厌氧污泥床（UASB）反应器进行基质浓度为稳定运行浓度的1.5倍和2.0倍，HRT为稳定运行时的2 / 3倍和1/2倍，以及Cu（Ⅱ）浓度为5.95mg/L和12.9mg/L，单独或联合进行持续时间为2到4 小时的冲击反应试验。不同的冲击反应试验，厌氧氨氧化系统的脱氮效率的差异很大。联合冲击对系统影响的大小顺序是：（基质冲击+水力冲击）>（基质冲击+重金属冲击）>（水力冲击+重金属冲击）。基质和水力冲击影响由厌氧氨氧化活性（SAA）体现，SAA最大损失率分别为51.9％和63.6％。 基质和水力冲击的联合效应抑制SAA，而重金属和水力冲击结合对SAA无严重影响。因此，该系统表现出相当大的弹性能承受一定的冲击强度。71151

Factors such as substrate fluctuations, increased inflow rates and heavy metal presence exert inpidual and combined effects on anaerobic ammonium oxidation (anammox) systems in real applications; therefore, the performance stability and resilience of such systems were investigated in an upflow anaerobic sludge blanket (UASB) reactor. A 1.5- and 2.0-fold increase in substrate concentration, 2/3- and 1/2-fold decrease in hydraulic retention time (HRT), and 5.95 and 12.9 mg L 1 transient Cu(II) shock were applied either inpidually or in combination for durations of 2 and 4 h. The nitrogen removal efficiency of the system varied considerably when all of the shocks were applied. The magnitude of the effect of the com- bined shock loads on the system decreased in the following order: (substrate shock + hydraulic shock) > (substrate shock + heavy metal shock) > (hydraulic shock + heavy metal shock). The specific anammox activity (SAA) was adversely affected by the inpidual substrate and hydraulic shocks, with maximum SAA loss rates of 51.9% and 63.6%, respectively. The SAA was inhibited by the substrate and hydraulic shock combination, whereas it was not strongly affected by the heavy metal and hydraulic shock combi- nation. Thus, the system could withstand certain shock intensities and exhibited considerable resilience.
