基于前馈控制模型的生化反应池曝气控制优化

Optimization Aeration Control of Reaction Tank Based on Feed Forward Control Model

污水处理厂是电能消耗大户,生化反应池的耗电量占到全厂的40%左右。如何优化生化反应池的曝气控制,在保证出水水质稳定合格的前提下,尽量减少曝气量,节约能源和运营成本,是污水处理厂需要认真考虑的问题。介绍了采用前馈控制系统,基于进出水水质、流量等测量值建立模型,实时计算溶解氧设定值,控制曝气量,实现按需曝气。

This paper introduces the feed forward controI system,based on measured vaIue of inIet and outIet water quaIity,fIow rate,etc.to estabIish the controI modeI,caIcuIate the setpoint of dissoIved oxygen on reaI-time,controI aeration rate,achieve aeration according to requirement.
