Benefits of technology

This new technology uses nontoxic substances that are safe from humans but can be absorbed into fish or algae cells without causing damage. It also works at very small doses compared to existing techniques while being more efficient than current methods like bioremediation. Additionally, this process does little waste over time due to its effectiveness on water quality.

Problems solved by technology

This patents discuss two technical problem areas: one relates to controlling or reducing contamination caused from humans' activities that use clean waters during certain periods (such as heatworm) while another focus on prevention measures like bioremediation techniques used at sea level. These approaches have limitations because they require significant amounts of time, materials, labor, etc., which may affect fish populations and other organisms living near these locations.

example 1

[0040] at every 30m 2 Put 30g of the above-mentioned cyanobacteria into the area of ​​the airtight box that has become light and black after being treated with mold, and cover the entire water body in different areas; after 3 days of putting in, large pieces of cyanobacteria died in the river, and the mortality rate reached more than 80%.

example 2

[0042] at every 40m 2 Put 40g of the above-mentioned cyanobacteria into the area of ​​the airtight box that has been treated with mold and become light and black, and cover the entire water body in different areas; after 4 days of putting in, large pieces of cyanobacteria died in the river, and the mortality rate reached more than 82%.

example 3

[0044] at every 50m 2 Put 50g of the above-mentioned cyanobacteria into the area of ​​the airtight box that has been treated with mold and become light and black, and cover the entire water body in different areas; after 5 days of putting in, large pieces of cyanobacteria died in the river, and the mortality rate reached more than 85%.

Abstract

The invention relates to a blue alga removal method, and belongs to the field of water environment protection. The alga removal method is provided against the abuse of temporary problem solving of present blue alga processing methods. The method is characterized in that a mixed solution containing cyanotoxins extracted from blue algae and a cyanotoxin and algophagous Aristichthys nobilis internal organ and tissue extract liquid goes moldy, the moldy mixed solution is cultured, and a mold solution is extracted to control blue algae in rivers in order to remove blue algae. Compared with traditional methods, the method used in the invention has the advantages of high blue alga treatment efficiency, low energy consumption, no use of chemical agents, no damages to aquatic animals and plants, and no entrance to human bodies through the food chain.
