摘　　要：在中试装置中以A2/O2工艺(缺氧-厌氧-微氧-好氧)处理氮肥废水,通过控制运行条件实现稳定的亚硝酸氮积累后,采用间歇试验的方法,以微氧池中富含亚硝化菌的活性污泥为试验对象,研究了该工艺在常温下处理氮肥废水的短程硝化动力学特性,分别考察了氨氮的降解特征以及MLSS与MLVSS之间的关系,并分析了SVI、ORP对氨氮去除的影响,建立了短程硝化动力学方程。The A2/O2 （Anoxic-anaerobic-microaerobic：aerobic） process was used to treat nitric fertilizer wastewater in a pilot-plant. Afterachieved stable accumulation of nitrite nitrogen by controlling the operating conditions, an intermittent experiment was conducted to investigate the kinetic characteristics of the shortcut nitrification process about the sludge derived from the micro-oxygenation pool which was rich in nitrosobacteria. In this paper, the degradation characteristics of ammonia and the relation between MLSS and MLVSS were evaluated firstly, and then the influence of SVI and ORP on ammonia removal rate was analysed, finally a dynamics equation of the shortcut nitrification process was established.
