几种增氧方式对黑臭河湖的治理效果对比
|
摘要
为了解如何更好地治理黑臭河湖,本研究在对比了市面上的几种增氧机械特点后,设置多组对比试验,从水体含氧量的测定和水温的测定出发进行试验,以期对比曝气微孔增氧与机械增氧的区别。用多种不同的增氧方式对同一池塘进行测定(9—10月),获得池塘表层与底层的溶氧量、水温差等指标数据。结果表明,曝气微孔增氧技术具有更高的性价比,对于水中的溶氧量增加更有效果,同时对于时段性温差明显地区水层表层与底层的温差调节作用明显,有更强的降温效果。
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 as to compare micro-pore aeration and mechanical aeration. Using a variety of different aeration methods in the same pond(September to October), we determined the amount of dissolved oxygen, temperature difference of surface and the bottom of the pond, etc. The results showed that:the micro- pore aeration method had a better cost performance, and was more effective for increasing the amount of dissolved oxygen in the water, at the same time, in some areas, the range of temperature changed with different periods of time, the effect of adjusting the temperature difference from water surface to the bottom was obvious, and had better cooling effect.
