Abstract: The present disclosure relates to water environment governance technology, and particularly discloses an urban river/lake water environment multi-interface governance and restoration method. The method is a multi-interface coordinated governance and restoration method based on “control for bottom, regulation for middle and governance for top”, including: “control for bottom”—controlling the emission of sediment nutritive salts and the dormancy and recovery of algae; “regulation for middle”—regulating primary productivity in a water body to inhibit the recovery of the algae; and “governance for top”—reducing nitrogen and phosphorus nutrients of an air-water interface to control the reproduction and growth of the algae. In the present disclosure, the water body governance and restoration technology based on interface coordination can effectively inhibit the outbreak of cyanobacteria and avoid extreme conditions in the ecosystem.

Abstract: The present invention relates to the field of water environment treatment, and particularly discloses a system and method for restoring a river and lake water body by a floating type water purification plant. The method comprises: (1) under the action of a water pump, enabling the river and lake water body to pass through a grille to be filtered; (2) lifting the filtered water body to an ss sedimentation tank by the water pump through a water inlet pipe, and carrying out pre-magnetization on the water body in the water inlet pipe by a pre-magnetization device arranged in the water inlet pipe; (3) enabling the water body subjected to pre-magnetization treatment to enter the ss sedimentation tank so as to remove particles in the water body; (4) enabling the water body treated by the ss sedimentation tank to enter a magnetizer to be subjected to magnetization treatment under a magnetic field intensity of 50 mT to 2,000 mT; and (5) distributing the water body subjected to magnetization treatment at the upper part of the floating type purification plant. According to the present invention, for the river and lake water body, for different growth periods of aquatic plants, the magnetic field intensity of the magnetizer for carrying out magnetization treatment on the water body is regulated for inducing growth of plants and beneficial indigenous microorganism communities, so that the purifying capacity and reliability of an ecological floating bed technology are reinforced.

Abstract: 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.
