摘　　要：在广州市白云湖水利工程不同水域布置9套微纳米气泡发生装置,并对其曝气效果进行试验研究。结果表明:本监测周期内,曝气装置溶解氧的增幅与处理水体的溶解氧本底值有关,在同等条件下,本底值较低时增幅大于本底值较高时,单套曝气装置单位距离平均增氧效果达到0.16%/m;流速对曝气装置的增氧效果影响比较明显,流速越快,单位时间距离内溶解氧的增幅越低;单套曝气装置单位时间内的平均增幅为6.684%/min,综合所有费用情况,每套装置的增氧效率为0.15元/%,按白云湖一台泵单位时间引水量8.6 m3/s换算每套装置的吨水处理费用为0.001 9元/m3;微纳米曝气装置对白云湖工程水质改善项目溶解氧指标的改善具有一定的作用。The nine Micro Bubble Generators（ MBG） were constructed in different areas in Baiyun Lake in Guangzhou City, and the aeration effect was experimented. The result showed that the dissolved oxygen （ DO ） increase rate was higher under the lower back-ground value of dissolved oxygen（ DO） by the MBGs, and the single MBG could increase DO 6. 684 %/min and 0. 16 %/m, which was impacted by the flow velocity oppositely. The aeration efficiency of each MBG cost ￥ 0. 15/%, and the tons water treatment of each MBG cost ￥ 0. 0019/m3 according to the condition that 8. 6 m3/s water was pumped to the BaiYun Lake. The MBGs had certain effect on the quality of Baiyun Lake engineering project to improve dissolved oxygen.
