Technical Field

The invention belongs to the field of water body pollution treatment, and particularly relates to a composition for removing aquatic blue-green algae.

Background

Blue-green algae (blue-green algae) is a large unicellular prokaryotic organism which has long evolutionary history, is gram-negative, has no flagella, contains chlorophyll a, does not contain chloroplast (algae different from eukaryotes) and can perform oxygen-producing photosynthesis, in some water bodies with rich nutrition, some blue-green algae are usually propagated in summer, and form a layer of blue-green floating foam with fishy smell on the water surface, which is called water bloom, large-scale blue-green algae outbreak, which is called green tide (corresponding to red tide generated by the sea), the green tide causes water quality deterioration, and the oxygen in water is exhausted seriously to cause fish death.

Since blue algae adversely affects the environment and fishery production, effective and safe biochemical means are needed to solve the problem.

Disclosure of Invention

In view of the above, the invention aims to provide a composition for killing aquatic blue-green algae, which has the positive characteristics of strong complementarity, obvious synergistic action, high algae killing speed, reduced application amount, prolonged application suitable period, safety to aquatic organisms, reduced environmental pollution, strong environmental compatibility and the like.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

the composition for removing the aquatic blue algae is prepared from the following raw materials in percentage by weight: 66.6 percent of chlorobromoisocyanuric acid and 33.4 percent of bacillus laterosporus.

Furthermore, the mass content of the chlorobromoisocyanuric acid is 50%, and the content of the bacillus laterosporus flora is 10 hundred million/g.

Further, the effective period of the chlorobromoisocyanuric acid is 24 months, and the effective period of the bacillus laterosporus is 18 months.

Furthermore, the chlorobromoisocyanuric acid is an effective bactericidal component, is a very small bactericidal component with prevention and treatment effects on fungi, bacteria and viruses in the field of pesticides, mainly releases hypobromous acid and a small amount of hypochlorous acid after being dissolved in water, the cyanobacteria death is caused by the substances destroying the membrane structure of cyanobacteria cells, and the final metabolite of the chlorobromoisocyanuric acid is triazine and triazine diketone components which are antiviral agents most widely applied in the field of medicines, so that the chlorobromoisocyanuric acid has an outstanding prevention and treatment effect on the viral diseases.

Furthermore, the bacillus laterosporus is a natural strain approved by the center for detecting microorganisms of the ministry of agriculture, the extracellular substances secreted by the bacillus laterosporus can directly touch and kill blue-green algae cells, the activity of microscopic organisms of phytoplankton is promoted, the bacillus laterosporus has the function of secreting a large amount of chitinase, the chitinase can decompose the cell walls of fungi to inhibit fungal diseases, and experiments prove that the bacillus laterosporus can decompose residual feed, excrement and organic matters in water.

The preparation method of the composition for killing the aquatic blue algae comprises the following steps:

(1) stirring the chlorobromoisocyanuric acid and the bacillus laterosporus according to the proportion of 2:1, and uniformly mixing;

(2) and (2) putting the mixture obtained in the step (1) into a barrel, covering and sealing the barrel, and performing anaerobic fermentation for 2 days at the ambient temperature of 20-25 ℃ to obtain the composition for removing the aquatic blue algae.
