摘要/Abstract

摘要： 厌氧氨氧化工艺已经广泛应用于侧流处理，但在主流条件下应用时，尚存在一定难度。在主流应用时，需要先对污水进行预处理，消除碳、磷的影响，然后再通过控制温度、溶解氧等因素来保障厌氧氨氧化过程的有效进行。影响厌氧氨氧化在主流工艺中应用的因素包括温度、pH和进水C/N等，还需考虑污泥形态、NOB抑制等问题，以保证主流工艺运行的稳定性。此外，厌氧氨氧化在侧流条件下的启动及主流条件时的稳定运行，均需通过多因素控制来实现。

Abstract: Anaerobic ammonium oxidation(Anammox) has widely been used in sidestream treatment,but there have been a certain difficulties in its application under mainstream condition. In its application to mainstream,it is necessary for the sewage to be pretreated firstly,so as to eliminate the influences of carbon and phosphorus,and then,to ensure the effective operation of the Anammox process through controlling the temperature,dissolved oxygen and other factors. The factors that affect the application of Anammox to the mainstream process include temperature,pH,influent C/N,etc. The problems that also need considering are sludge appearance,NOB inhibition etc.,in order to ensure the stability of the mainstream process operation. In addition,the realization of both the start-up of Anammox under sidestream condition,and the stable operation under mainstream condition still need multi-factor control.

Key words: Anammox, mainstream process, pre-treated, sludge forms, C/N
