| 摘 要： | 在低氧曝气短程硝化过程中，氧气是反应的限制因子，氧气的浓度和反应时间直接决定了氨氮的去除率。DO浓度0．25—0．75mg／L这一范围内，亚硝酸氧化速率很小，受DO浓度变化的影响也小；氨氧化速率相对较高，DO浓度对氨氧化速率影响相对较大。

| Abstract: | In the process of short - cut nitrification under low DO level, DO is the limiting factor of the reaction, the NH4^＋ - N Removal efficiency is decided directly by the oxygen concentration and the reaction time. In the low dissolved oxygen within the framework of（0.25 - 0.75 mg/L）, the oxidation rate of ammonia is high and markedly effeeted by DO value, the nitrous oxidation rate is small and little effeeted by DO value. |
