METHOD FOR SYSTEMATICALLY CONTROLLING RAPID PROLIFERATION OF CYANOBACTERIA CELLS IN LAKES IN SPRING

摘要

Disclosed is a method for systematically controlling the rapid proliferation of cyanobacteria cells in lakes in spring, the method comprising the steps of: using flexible enclosures to close and control a water area, and using FeCl₃, CaCO₃ and Ca(NO₃)₂ to treat sediment; using H₂O₂ to kill the algae, then using modified soil to adsorb sedimentary algae cells; arranging an ecological floating island in a closed water area, wherein the ecological floating island is composed of a floating bed for floating plants, a culture cage and a biofilm; arranging the culture cage under the floating bed for floating plants and raising filter-feeding fish and shellfish; hanging the biofilm at the lower end of the culture cage to make periphyton naturally grow; and introducing snails at the bottom of the lake in the water area of an algae control area.
