摘　　要：选取3种不同的微孔曝气设备,针对其向饮用水原水的增氧效果进行了中试研究。结果表明,微纳米气泡设备的增氧效果最好,年平均DO含量提升率为15.80%,氧利用率为11.8%;楔形微孔曝气器和微孔橡胶膜管的增氧效果比较接近,年平均DO含量提升率分别为9.74%、9.08%,氧利用率分别为0.77%和0.68%。3种设备在各季度的季平均DO含量提升率和氧利用率2方面均表现为春季>夏季>秋季>冬季。微孔曝气设备的DO含量提升率和氧利用率会受水温和进水DO含量的影响,进水DO含量越接近饱和含量,其提升率和氧利用率则越低。Three different kinds of micropore aeration equipment were selected to conduct pilot-scale studies on the oxygenation enhancement effect of the drinking water resource. Results showed that the micro-nano aeration equipment had the best oxygenation effect. The annual average DO content increase rate was 15.80%, and the oxygen utilization rate was 11.8%. The aerobic effect of the wedge-shaped ring and the rubber membrane tube was relatively close. The annual average DO content increase rate was 9.74% and 9.08%, and the oxygen utilization rate was 0.77% and 0.68%, respectively.The seasonal average DO content increase rate and oxygen utilization rate of the three facilities in each season were spring > summer > autumn > winter.The DO content increase rate and oxygen utilization rate of the microporous aeration equipment were affected by the water temperature and the DO content in the influent. When the DO content of the influent water was closer to the saturation content, and the increase rate and oxygen utilization rate were lower.
