| 摘 要： | 本实验研究针对应用于面源污染控制的人工湿地中水生植物的选择和布置问题进行研究,通过对人工湿地动态运行实验的研究考察,发现床体中COD、TN降解规律,通过人工湿地栽种不同水生植物的各床体的COD去除效果比较实验和不同水生植物复氧性能比较实验,得出复氧性能最好的水生植物为芦苇,然后综合这三个实验,在传统的植物床系统基础上,提出更加有利于提高系统污水处理效率的改进形式:复合植物床式人工湿地。

| Abstract: | Detailed research on the selection and disposal of the hydrophytes in constructed wetland applied in non-point pollution control was done in this experiment. The removing rules of COD and TN in the constructed wetland beds were found in operation. The conclusion that the oxygen resuming capability of reed was the best was drawn after two experiments. The first experiment was the comparing experiment of the effect of COD removal in each bed with different hydrophytes, and the second one was the experiment of the capability of oxygen resuming of different hydrophytes. Then developed form of constructed wetland with composite plant bed that has higher effect of removing pollutants in wastewater was designed on the basis of the three experiments mentioned above. |
