  • 摘要: 实验采用鼓风曝气，改变曝气量，研究孔口分布及空气流速对清水充氧性能的影响。通过考察氧总转移系数KLa（20）、充氧能力N0和氧转移效率E 3项指标，得出该曝气设备的最佳运行条件：在曝气量为9 m3/h时，选用曝气器B进行曝气。这样可以得到较高的KLa（20）（1.816 h-1）、N0（0.105 kg/h）和E（4.151%），为曝气设备的实际应用提供参考。
    Abstract: The influence of orifice distribution and air velocity on rinsing oxygenation performance was studied by adopting blast aeration and changing gas flow. The test focused on investigating the following three indicators, the oxygen transfer coefficient KLa(20), oxygenation capacity N0 and oxygen transfer efficiency E. The results show that the optimal operating condition of the aeration equipment is aerating under the gas flow of 9 m3/h and choosting the aeration pipe B. In this case, the higher KLa(20) (1.816 h-1), N0 (0.105 kg/h) and E (4.151%) can be obtained, which provides a reference for the practical application of aeration equipment.
