Abstract: The invention discloses a method and a device for treating cyanobacteria in a water area based on the principle of biological competition, the method comprising: finding an area where cyanobacteria most easily accumulate, i.e. a concave bank of a water area, and setting up an algae interception net around the area; quickly and largely clearing the cyanobacteria in the area by means of manual or mechanical catching; planting emerged plants on the shoreline of the water area to fundamentally improve water quality; and additionally, densely arranging treatment tanks in a larger water area to kill the cyanobacteria gradually, and collecting dead cyanobacteria to prevent them from polluting the water area subsequently; and collecting and treating the tanks regularly for recycling.

Abstract: An ecological slope protection has an efficient water purification function, built in a land-lake ecozone along the bank of a basin, wherein the body of the ecological slope protection extends into the water of the basin, and has a flexible mattress laid on the surface thereof; an ecological filter pool is provided below the flexible mattress and is isolated from the water of the basin by means of the pool body; the ecological filter pool is contained with a filler layer and a support layer, and the filler layer is supported by the support layer; the sewage pretreated via a sedimentation pool is introduced into the ecological filter pool and treated by the filler layer to clean up pollutants therein and reduce its eutrophication level; and the treated sewage is discharged from the ecological slope protection via the support layer and enters the basin.

Abstract: A method for controlling the growth of blue algae in a basin relates to the field of the restoration and protection of the natural ecology on the earth's surface. An ecological water treatment system was constructed for the basin with microorganisms, plants, animals, fillers and the like as main elements by building a novel ecological slope protection at the land-lake ecozone along the banks of the basin and planting eucalyptus in the basin water and/or on the bank of the basin, thereby effectively realizing the efficient nitrogen and phosphorus removal from the basin, controlling the spread of blue algae and improving the environmental water quality.
