摘要
通过对栽种有芦苇和美人蕉的水平潜流人工湿地进行两年多的试验研究,分析人工湿地去除效果随运行时间变化的规律,探讨不同季节和温度对COD、TN和TP去除率的影响。试验结果表明,在最佳运行条件下,COD、TN和TP去除率可分别达到90%、65%和55%以上;从两年多的运行情况来看,COD和TN的去除效果变化不大,TP去除率下降显著。
Two kinds of subsurface horizontal constructed wetlands with reeds and cannas were researched for more than two years. We analyzed the changes of purification effect along with runtime and discussed the affection of seasons and temperature on COD,TN and TP. The results showed that the removal efficiencies of COD, TN and TP were above 90 %, 65 % and 55 % separately on the optimal conditions. Concerning with the two years＇ removal effect of constructed wetlands, the removal efficiencies of COD and TN had taken few changes, but the removal efficiency of TP had dropped dramatically.
