Abstract
The present invention relates to a method and a device for controlling pollutants in basin water used for irrigating farmland in extremely water-scarce areas. The device includes an alternate vertical flow constructed wetland, which is constructed 4-10 m far from basin revetment. After feeding basin water into the constructed wetland, pollutants, such as heavy metals, nitrogen, phosphorus and organic matters, are adsorbed or degraded through the constructed wetland, and then the treated basin water is transported to the farmland.
