【Abstract】 Pump-type impeller aerator is generally used for aerating and mixing device in traditional activated sludge process. Normative and operable means are insufficient at present to evaluate its performance in practical application. A new testing measure on oxygen transfer coefficient-K La W in wastewater was suggested and applied to an energy efficiency research on a wastewater treatment plant located in Chongqing. Through the measure, relationship between K La W and aeration power density, as well as relationship between oxygen capacity, energy efficiency and rotating velocity of impeller were studied, and an operation scheme for energy saving was suggested and adopted.更多还原
