摘　　要：以曝气生物滤池为载体,研究了NH4+-N浓度、pH、FA、DO对曝气生物滤池内NO2--N积累的影响及沿滤池高度NO2--N积累情况。试验表明,在一定的条件下,曝气生物滤池内发生了同步硝化反硝化和短程硝化反硝化,且在某高度处可以实现较高的氨氮去除率和NO2--N积累率。This paper discusses the accumulation of NO2^- -N influenced by the concentration of NO4^＋ -N, pH, FA and DO, and the accumulating situation along the reactor. The study shows that under specified conditions, simultaneous and shortcut nitrification and denitrification takes place in the reactor and a high removal rate of NO4^＋ -N and accumulation rate of NO2^- -N can be realized simultaneously in some part.

关 键 词：曝气生物滤池 短程硝化 游离氨NO2^- -N
