The disclosure relates to the field of water environment treatment, and more particularly to a system and a method for restoring a water environment by a constructed wetland. The system for restoring the water environment by the constructed wetland includes: (1) a water distribution pipe for inputting a water body to be treated into the constructed wetland; (2) a magnetization reactor arranged around the water distribution pipe and used for applying a magnetic field perpendicular to the water flow direction to the water body flowing through the water distribution pipe in order to make the water body entering the constructed wetland through the water distribution pipe become magnetized water after magnetization treatment; (3) the constructed wetland; (4) a magnetization reactor arranged in the vertical direction of the constructed wetland and used for applying a magnetic field to the constructed wetland in the vertical direction; and (5) a water outlet pipe used for discharging the water body treated by the constructed wetland. The water body to be treated passes through the water distribution pipe, is treated by the magnetization reactor arranged around the water distribution pipe and then enters the constructed wetland. Meanwhile, the magnetization reactor arranged in the vertical direction of the constructed wetland is used for intermittently magnetizing the constructed wetland, so that the technical problems of high blocking possibility during operation and difficult rapid restoration of the constructed wetland can be effectively solved.
