Study on water improvement function,capacity of lifting water and oxygenation of a water-lifting aerator

Cong Haibing Huang Tinglin Miao Jingguang He Wenjie Yin Peijun(1.School of Environmental and Municipal Engineering,Xi'an University of Architecture & Technology,Xi′an 710055;2.College of Environmental Science and Engineering,Yangzhou University,Yangzhou 225009;3.The Group of Tianjin Water Company,Tianjin 300040)  
Water-lifting aerator is a water quality improvement device which is used to restrain algae growth and pollutant releasing from sediment in lakes and reservoirs,and a good effect was obtained from applications.A model of flow velocity was built up for simulating of the flow rate in the water-lifting aerator.Another model of oxygen transfer was also built up to calculate the amount of oxygen transferred from air to water in the air vessel of the waterlifting aerator.The flow velocity and the concentration of dissolved oxygen have been measured and calculated by using these models in test,the data calculated coincide with that measured,and these models were verified.
