摘　　要：鼓风曝气系统是大型污水处理厂工艺过程中的重要组成部分 ,其耗电量占全厂的 60 %以上 ,是处理厂耗电较大的系统。为保证该系统合理、经济的运行 ,提高鼓风机的自动控制水平势在必行。重点阐述了曝气系统中鼓风机自动控制的设计思想 ,从对鼓风机送气及对气量再分配两方面的控制调节入手 。Aeration system is the important part of the technological process in largescale sewage treatment plant. Its power consumption which is over sixty percent of the whole electric energy occupies more power in the whole plant. For ensuring the system reasonable and economic operating, raising the air blower electromatic control standard should be imperative. The article expounds the design thought on the air blower electromatic control system. Starting with control and adjustment in air blowing and flowrate re distribution, the article also makes analysis on the mode of automatic operation for single blower and multi blowers.
