摘    要: 提出一种新型的复合垂直流湿地系统(IVCW),并对其反应动力学和系统的实际流态进行了研究.经过中试的运行试验,得到了系统对COD去除的反应速率方程,由示踪剂试验确定了系统中水流的停留时间分布(RTD),提出RTD的不同是湿地处理效率差异的主要原因,进而运用串联反应器模型和离散流模型两种非理想流态模型,模拟IVCW的实际水流流态,经过比较发现离散流模型模拟的效果较好.

关 键 词:复合垂直流湿地  反应动力学  停留时间分布(RTD)  串联反应器模型  离散流模型

Abstract:A new type of integrated vertical-flow constructed wetland (IVCW). system was presented and its reaction kinetics and the actual flow pattern of the system were studied. Based on the operation experiment of medium-scale, the reaction rate equation of COD removal for the system was obtained and the retention time distribution (RTD) of water flow in the system was assured through. RTD difference was presented as the main cause of the diversity of the wetland treatment efficiency; and the actual water flow pattern of IVCW was further simulated using not ideal of the dispersed flow model and reactor in series model. It was found that the former model was more effective than the latter for simulation.
Keywords:integrated vertical-flow constructed wetland (IVCW)  reaction kinetics  retention time distribution (RTD)  reactor in series model  dispersed flow model
