摘　　要：采用序批式生物膜法对不同溶解氧(DO)、温度和pH值条件下氨氮的硝化效果进行试验研究,对运行过程中亚硝氮的积累进行探讨.结果表明,DO(4.0时NH3—N的去除率始终保持在95%以上;低pH值和低温对硝化反应有着明显的抑制作用,但低pH值对硝化反应的抑制是瞬时的,而低温对硝化反应的抑制是持久性的;控制低DO实现短程硝化时,在运行初期较易实现.To investigate the nitration effects in different DO, pH value, temperature and nitrosation accumulation in sequencing biofilm batch reactor by experiments. The results indicated that DO 〉 4.0, nitrogen removing rate maintains above 95% ; low pH value and low temperature has obvious inhibitory action to nitration, but low pH value infection is instant while low temperature infection is durable. When controls the low DO condition to realize shortcut nitration, it is easier to form nitrosation accumulation in initial period of the experiment.
