摘　　要：采用3种基质(中粗砂、煤灰渣、高炉渣)为试验材料,填充高度分别为1.0、1.2、1.4 m,研究垂直流人工湿地模拟系统在水力负荷42 cm/d条件下对珠江水中的主要污染物总氮(TN)、总磷(TP)、COD的净化效果。研究结果表明,人工湿地垂直流模拟系统对珠江水中TN、TP和COD等污染物具有较好的净化效果,其平均去除率分别可达到56.16%、93.49%、86.96%;随着填料柱高度的增加,其去除率也增加。The experiment used three different kinds of substrates （the medium coarse sand, blast furnace slag and cinder） as materials, and also used three height 1.0 m, 1,2 m, 1.4 m to set up the text. In order to study the purifying function of the Pearl River＇s water about the constructed wetland system under the hydraulic： with 42 cm/d. The results showed that the constructed wetland system had obvious purifying function of the Pearl River, s pollutant TN ,TP,COD.The removal rate of TN ,TP,COD could reach 56.16%,93.49%, 86.96%, respectively. The removal rates of systems were improved obviously with the increasing thickness of substrates.
