A water flea domestication method and a method for using water fleas to carry out ecological restoration of water bodies

Abstract

The purpose of the present invention is to propose a method of domestication and use water to repair the ecological repair of the water body.And / or increase the concentration of the toxic substances in the cultivation solution until the temperature of the cultivation liquid reaches the predetermined temperature and / or the concentration of the toxic substances in the culture liquid to the highest concentration of the predetermined.Algae toxin ‑LR, completes the temperature and domestication of water turmoil and the toxic substance tolerance.The water -based water tadpoles that are domesticated in accordance with the current invention of the water crickets are put into the water body that is severely contaminated with toxic substances and algae.

Description

technical field

[0001] The invention belongs to the fields of environmental protection and biotechnology, and in particular relates to a method for domesticating water fleas and a method for ecologically restoring nutrient-rich water bodies by using water fleas. Background technique

[0002] The reason why the algae in the water broke out is that various human production activities discharge nutrients such as nitrogen and phosphorus into rivers, lakes and other water bodies. When the ecological self-purification ability of lakes is destroyed, nutrients such as nitrogen and phosphorus continue to accumulate in the water body. The accumulation of a large number of single-celled algae, especially cyanobacteria (mainly Microcystis aeruginosa) floods and seriously pollutes the water quality. Most of the cyanobacteria cells have a well-developed alginate layer and are surrounded by a thick layer of polysaccharides. These alginates and polysaccharides can hardly be decomposed by th...
