Abstract: The influence of nitrogen loading and high temperature shock on ANAMMOX (anaerobic ammonium oxidation) process with a 3.2 L UASB (up-flow anaerobic sludge blanket) reactor was investigated. The results showed that the UASB-ANAMMOX reactor is not only appropriate for the treatment of low ammonia containing wastewater, but also suitable for that of mediate to high ammonia containing wastewater. The nitrite reductase is more likely subjected to the inhibition of dissolved oxygen. A instant high temperature may give a heavy shock on the running of the reactor; however, the shock may be relieved because of an intrinsic mechanism caused by the ANAMMOX microbes, which resulted in the resilience of the reactor to a steady state.

摘要： 采用一套有效容积为3.2 L的上流式厌氧污泥床-厌氧氨氧化（UASB-ANAMMOX）反应器，研究氮素负荷和高温冲击对ANAMMOX反应器运行效果的影响。试验结果表明，UASB-ANAMMOX反应器不仅适用于处理低浓度含氮废水，也可用于中、高浓度含氮废水处理；溶解氧（DO）对亚硝酸还原酶（NR）的抑制作用更强；瞬间高温能对反应器运行效果产生强烈冲击，但反应器内的ANAMMOX菌群有解除高温抑制的内部机制，能保证反应器的稳定运行。
