摘要
在相同的水力负荷下以水平潜流人工湿地(SFCW)作为对照,进行了波形潜流人工湿地(W-SFCW)在不同的HRT下处理模拟生活污水试验。结果表明,W-SFCW对污染物尤其是氮、磷的去除效果明显优于SFCW。HRT为1 d时对TN和NH4+-N的去除效果最好,HRT为2 d时对TP的去除效果最好,HRT为2 d时COD的去除效果较好。在此条件下,W-SFCW对COD、TN、NH4+-N和TP的去除率分别比SFCW提高了10%、17.2%、11.6%和27.4%。
In this text, the Wavy Subsurface Flow Constructed Wetland (W-SFCW) and the Horizontal Subsurface Flow Constructed Wetland (SFCW) were supplied with the same hydraulic loading rate of simulated domestic wastewater through the whole experiment; It could conclude that the nitrogen removal efficiency of W-SFCW was better than of SFCW under the same hydraulic loading rate. TN and NH4+-N removal efficiency were the best when HRT for one day while HRT for the 2 d the removal efficiency of TP and COD were the best. Under these conditions, COD, TN, NH4+-N and TP removal rates of W-SFCW were higher than SFCW 10%, 17.2%, 11;6% and 27.4%.
