| 摘 要： | 为了解决A/A/O工艺污水处理系统在进水负荷波动较大时曝气池中溶解氧(DO)的波动范围大的问题,该文以某A/A/O工艺的污水处理厂作为试运行系统,进行DO的自动控制优化研究,在传统的DO控制方法上加入曝气池的模型算法来进行DO控制的优化设计.试运行系统运行表明该控制方法可以使DO的控制精度范围达到±0.2mg/L.

| Abstract: | In order to solve the problem of large fluctuation of DO in aeration tank when large water load fluctuation in A/A/O process, a wastewater treatment plant of 200 000 m3/d was used to investigate the optimization of automatic control of A/A/O process. Adding algorithm of aeration tank model on the basis of the traditional system. Test run shows that the optimal control system can make the DO control accuracy range of ±0.2 mg/L. |
