| 摘 要： | 对A/O工艺研究了不同运行条件下曝气量对硝化过程的影响,以及好氧区pH和DO浓度的变化规律。发现随着曝气量的增加,平均硝化反应速率提高,平均DO浓度增加,但增加幅度降低。需通过控制曝气量大小,间接的控制硝化反应速率,使出水达标排放。可以应用平均溶解氧浓度和pH曲线上是否出现拐点,来判断反应系统的曝气是否过量、适量或不足。

| Abstract: | The effect of aeration rate on nitrification, and the variation rules of DO and pH in aerobic zones,were studied at different operational conditions.It is found that the average nitrification rate and DO concentration were gradually increased,but the increased range was reduced.The nitrification rate could be indirectly controlled by aeration rate,so as to meet the effluent standard.The average DO concentration and the type of pH profiles could be used to determine the aeration if excessive, sufficient or insufficient. |

| Keywords: | aeration rate DO pH A/O process and control |
