摘要
以西安市兴庆湖为研究对象,对湖泊的水质进行了水平潜流和自由表面流净化的实验研究,比较了两种湿地的净化效果。在相同的水力负荷、水力停留时间、水深等条件下,分析了两种人工湿地对城市湖泊中的有机物、氮、磷等主要污染物的净化效果,及不同影响因素对系统处理效果的影响,比较了两种人工湿地的优缺点。
This text deal with the purification efficiency of pollution lakes by the two kinds of constructed wetland （horizontal subsurface flow and surface flow）. The purification efficiency of constructed wetland was investigated for the main pollutants： organic compounds,nitrogen, phosphorus and so on at the same hydraulic loading rote,hydraulic retention time and water depth, As well as the different influence factors have effect on the treatment removal of system, Compares the advantages and disadvantages of the two kinds of constructed wetland.
