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.
