摘　　要：污水处理厂是能耗大户,其中曝气池消耗的电量约占全厂的40%～70%。提高曝气池供气的自动控制水平,在达到处理要求的前提下尽可能降低曝气量,是节能降耗的重要措施。论述了曝气控制的策略,重点介绍了精确DO控制的原理和方法。The wastewater treatment plant is a big energy consumer and the electric power that aeration tank consumes accounts for 40%-70% of total electric power. It is very important for the energy-saving and consumption-reducing measures to improve the automatically controlled level of the air supply and reduce the air consumption as much as possible on the premise of reaching treatment requirements. This paper has described the tactics for aeration control and introduced principles and methods of accurate DO control especially.
