| 摘 要： | 采用生物膜ASBR反应器,研究了厌氧氨氧化反应过程中亚硝氮与氨氮降解速度的变化规律。结果表明,降解过程主要分为2个阶段:速度上升期(0~30 min)和速度下降期(30~150 min)。一阶指数衰减模型的模拟结果表明,20 min以后亚硝氮、氨氮降解速度逐渐减少,亚硝氮降解速度始终高于氨氮降解速度,但是两者差值随时间逐渐减少。

| Abstract: | An ANAMMOX ASBR utilizing non-woven fabric carriers was used to investigate its bio-degrada-tion rule of nitrite and ammonium.Research results showed that there were two different phases in the process of nitrite and ammonium degradation,the increase of degradation velocity(0-30 minutes)and the decrease of degradation velocity(30～150 minutes).Simulation results according to first order exponential decay model demonstrated that degradation velocity of nitrite and ammonium decreased with time after 20 minutes,and degradation velocity of nitrite was always faster than of ammonium.However,the gap of velocity between them declined with time. |
