污水处理生化池曝气量的智能控制系统

针对国内大多数污水处理厂曝气量的分配、供应效果很不理想,溶解氧浓度控制滞后、精度低、波动大、能耗高以及直接影响处理效果。本文叙述了已成功开发并应用的污水处理生化池曝气量的智能控制系统。该系统能在水质水量不变时和变化时,采用串级、前馈、反馈控制和智能模型,保证曝气平衡,并根据阀门的开度大小,调节鼓风机的操作压力,达到节能的目的。本文对控制系统的设计思想、系统配置、控制算法、软件设计作了重点介绍,并给出了实际使用效果。

Intelligent controlling System of the aeration quantity in wastewater treatment biochemistry tank

In view of the existing problem of the majority domestic wastewater treatment plant,such as the aeration quantity assignment and the effect of supply are not very ideal, the lag controlling of the dissolved oxygen concentration ,and its low precision, big fluc-tuations, high energy consumption ,which directly influence the processing effect. This paper describes the succeeded developed and used intelligent system which controls the aeration quantity of the wastewater treatment biochemistry tank. This system will use the se-ries, the forward feed, the feedback control and the intelligence model to guarantee the balance of aeration whether the quality and quantity of the water change or not .At the same time, according to the opening size of the valve, it will adjust the service pressure of the air blower for the sake of saving energy. This paper emphasizes the introduction of the design idea, the configuration, the arithmetic, the software design of the control system. In the mean while, the actual use effect is given.
