Application of acetylacetone in inhibiting growth of blue-green algae

Abstract

The invention provides an application of acetylacetone in inhibiting growth of blue-green algae. Acetylacetone is added into a blue-green algae growth water area, and the adding amount is not less than 7mg / L, so that the growth of the blue-green algae is controlled; acetylacetone acts on a photosynthetic system to control the growth of algae, the effect of acetylacetone is superior to that of a common algistat (such as pyrogallic acid, gallic acid and anthraquinone), acetylacetone is harmless to bacteria including four common bacteria including escherichia coli, salmonella, bacillus subtilis and staphylococcus aureus, and acetylacetone has environmental friendliness and is easy to apply and popularize.

Description

technical field

[0001] The invention relates to the field of algae inhibitors, in particular to the application of acetylacetone in inhibiting the growth of cyanobacteria in eutrophic water bodies. Background technique

[0002] In recent years, cyanobacteria blooms caused by eutrophication of water bodies have seriously affected people's lives. Cyanobacteria blooms will not only cause the death of other aquatic organisms and change the aquatic ecological environment, but also directly affect the safety of human water supply. Cyanobacteria are generally divided into drug-producing strains (such as FACHB-905) and non-drug-producing strains (FACHB-469), wherein the drug-producing strains release microcystins that are toxic to the liver. Microcystis aeruginosa is the most typical algae during water blooms, and it is also the most common toxic cyanobacteria. It has strong viability and is difficult to remove. Therefore, it is of great significance to effectively control the grow...
