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.
