| 摘 要： | 选取芦苇、菖蒲、美人蕉和香蒲等4种南京地区常见的人工湿地常用植物作为供试植物,对其在春季对生活污水总氮(TN)去除效果的数学模型进行研究.通过监测引种植物后污水中TN浓度,利用回归分析建立湿地植物去除污染物的数学模型.结果表明:在毒季种植植物后污水中的TN浓度按线性关系减少,其中芦苇、菖蒲和香蒲对污染物的去除效果明显,其直线的相关系数分别达到0.927,0.929和0.979;美人蕉在春季对TN的去除能力较差,其线性仅为0.561. |

| Abstract: | A mathematic model was designed in this article in order to describe the removal efficiency of the plants used in the constructed wetland. reed (phragmites communis), cattail(yypha latif olia), calamus (acorus calamus Linn) and canna(canna generalis) were the plants adopted in this study, watching the change of the total nitrogen and recording the data. By analyzing the data with the way of linear regression, a mathematic model was gotten and the accuracy of this model reaches 0.927, 0.929 and 0.979, respectively. This result shows that the removal efficiency of wetland plants obeys the liner model in spring and reed, cattail and calamus are the suitable constructed wetland plants for the season of spring. |
