Abstract: In order to study the aeration performance and pond application effects of microporous aerators, test of aeration performance, test of effects of different water depth on aeration performance and test of application effects in the pond are respectively conducted according to methods specified in the standard. The results show that microporous aerators have greater aeration capacity than impeller aerators and other ones, but among different configurations, the aeration capacity increases with the matching power and pipe length, while the power efficiency decreases significantly. The aeration performance can be improved by increasing pipe installation depth, for example, if the installation depth is increased from 2m to 4m, the aeration capacity will increase by 285% and the power efficiency by 207%; compared with other mechanical aeration, the deeper the water in the pond is, the more obvious the aeration advantage of the aerator is. At present, the configuration of microporous aerators has no advantage and needs to be improved.

摘要： 为研究微孔曝气增氧机的增氧性能和池塘应用效果，按照标准规定的方法进行了增氧性能的试验、不同水深对增氧性能影响的试验，并在池塘中进行应用效果的试验。结果显示：微孔曝气式增氧机具有比叶轮式增氧机等增氧机更强的增氧能力，但不同配置的机型，增氧能力随配套功率和曝气管长度的增加而增强，动力效率则呈明显下降趋势；增加曝气管布置深度可以提高增氧性能，安装深度从2 m增加到4 m, 增氧能力增加285%，动力效率增加207%，与其它养殖池塘机械增氧设备相比，池塘水体越深，曝气式曝气机的增氧优势越明显。目前，池塘曝气式增氧机的配置方式不具优势，需要改进提升。
