%X A comparative study on oxygenation capacity of several inverted umbrella surface aerators produced by one technology company in Anhui Province was conducted.Overal oxygen transfer coefficient(KLa),oxygen transfer rate(qc),the oretical power efficiency(E) and the velocity(v) in clear water were tested using a oxidation ditch device located in Hefei,and analyzed the influence on the oxygenation capacity among the blade installation angle,the number of blades and the design of blade.The result shows that angle of the flow-guide plate design is the greatest impact on oxygenation capacity and also is the most critical factor on the impeller performance improvement.
