| 摘 要： | 通过示踪剂实验,采用停留时间分布(RTD)理论对不同出水口高度下垂直流人工湿地内的水流流态进行了分析。研究表明水流在垂直流人工湿地中的流动是介于理想的活塞流和全混流之间的非理想流动状态;不同出水口高度下,垂直流人工湿地内水流流态的不同主要体现在水流在人工湿地内停留时间的长短上面,而水流的分散程度相差不大;出水口较高时,水流在垂直流人工湿地内的平均停留时间也较长,该水流流态有利于污染物在人工湿地中的降解。

| Abstract: | The water flow patterns in the vertical flow constructed wetlands were analyzed with different height of water outlet,based on the tracer experiment by using the theory of the resident time distribution（RDT）.The results indicated that the actual flow pattern was between the ideal plug flow and continuous stirred flow.The main difference of the flow pattern under different height of water outlet was the mean resident time and the difference of the dispersion can be neglected.When the water outlet was higher,the mean resident time was longer,and this was favorable to the degradation of the pollutants in the vertical flow constructed wetland. |
