| 摘 要： | 通过对栽种芦苇(Phragmites australis)、香蒲(Typha latifolia)和菖蒲(Acorus calamus)3种植物的潜流人工湿地进行试验研究,分析3种植物对污水的净化效果,及在不同水力停留时间下的变化规律.试验结果表明,在最佳运行条件下,COD、TN、TP的去除率分别在50%、75%和65%以上;3种植物对比可以看出,香蒲的净化效果明显好于芦苇和菖蒲,香蒲对COD、TN、TP的去除率分别达到67.2%、89.7%、88.9%.

| Abstract: | This article through the test research of subsurface flow constructed wetland, which plants reeds (Phragmites australis), cattail(Typha latifolia)and acorus calamus(Acorus calamus) respectively, analyzed effect of three plants on the purifying the sewage, and different Hydraulic Retention Time (HRT) under the law changes. The results show that in the best operating conditions, COD, TN, TP in the removal rate of 50%, 75% and 65%. Three plants contrast test presents that cattail purifying effect is significan... |
