【摘要】 扬水曝气器是水源水质改善设备,应用于湖泊水库水源地,抑制藻类生长,控制底泥污染物释放,取得了良好的效果。建立了扬水曝气器上升流速数学模型,用于模拟计算扬水曝气器的提水能力。建立了扬水曝气器曝气室的充氧能力数学模型。在实验室实测了扬水曝气器上升流速及其对水体的充氧过程,实测值与模拟计算值吻合较好,验证了提水、充氧能力数学模型。更多还原

【Abstract】 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.更多还原
