Abstract: In order to make a better management of odor rivers and lakes, after comparing several aeration equipment, the authors set multiple sets of comparative experiment to determine the type of pollutants and water temperature from different layers, so that we can make a comparison between micro-pore aeration and mechanical aeration methods. Using a variety of different aeration methods on the same pond (September to October), to determine the amount of dissolved oxygen, temperature difference of surface and the bottom of the pond etc. The results showed that: the micro-pore aeration technology had a better cost performance, was more effective for increasing the amount of dissolved oxygen in the water, at the same time, in some areas,the range of temperature changes with different periods of time,the function of adjusting the difference in temperature from water surface to the bottom was obvious in these areas, had better cooling effect.
