摘　　要：变频器用于曝气转刷的自控中,通过调节曝气转刷的转速,实现氧化沟需氧量与充氧量的最佳匹配,在保证出水水质的同时,可以最大限度的降低能耗。同时论证了变频调速的可行性和必要性。全面介绍了在实际应用中曝气转刷的三种控制方式,其中计算机系统自动控制方式中的变频调速控制可以实现节能。As VVVF (Variable Voltage Variable Frequency) used in the automatic control of aeration brush can realize the best matching of oxygen demand and oxygen supply through changing the revolving velocity of aeration brush in an oxidation ditch, as a result, the energy consuming is reduced in the greatest extent with guaranteed effluent water quality. At the same time, the feasibility and necessity of VVVF in the automatic control of aeration brush is proved. In this paper all ways of the control of aeration brush are introduced in the factual use. The energy saving can be achieved through the control of changing frequency in the automatic control ways of computer system.
