抄録: In order to attain the sound and sustainable water environment, it becomes important to reduce the pollutant runoff rates, especially from the nonpoint sources. Of course, accomplishment of sewerage system helps to attain the above purpose. At the same time, it is well known that there are some problems, such as CSO that is the Combined Sewer Overflow, financial restriction for treatment of stormwater, and so on. From these reasons, removal of pollutants by constructed wetland becomes to be interested, recently. In this paper, treatment efficiency of pollutants such as nutrients by constructed wetland has first been discussed referring to the some examples. Next, the velocity constant of treatment has been investigated, correlated to the flow rate of wastewater into the wetland and the hydraulic retention time in the facility. Finally, purification efficiency of water by the constructed wetland has been evaluated, carrying out the field observation by a facility in the Nagasaki University.
