| 摘 要： | 对一种新型的垂直流人工湿地系统的水流特性进行了研究。考察了系统的运行状况及介质中滞留区的分布范围，并且运用化学工程中反应器理论，采用示踪剂试验的方法得到了垂直流人工湿地系统的停留时间分布与污水的实际停留时间。根据水流停留时间分布函数对系统实际液流流态进行了数学模拟，提出二级串联的理想完全混合反应器（CSTR）模型能够较好地模拟垂直流人工湿地系统中水流的流动形态。

| Abstract: | The hydraulic pattern of the vertical flow constructed wetland was studied in this paper. The performance of the system and the dead space in the substrate was investigated firstly. The actual retention time was determined by the tracer experiment. According to the retention time distribution curve in the vertical flow constructed wetland, the actual flow pattern is modeled and it is found that two ideal continuously stirred tank reactors (CSTR) in series can simulate the flow pattern of the vertical flow constructed wetland adequately. |
