摘要：
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.
