Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, preferred embodiments of the present invention are described in detail below.

[0057] Embodiment of the method for domesticating Daphnia magna

[0058] By domesticating Daphnia magna, it can ingest blue-green algae in heavily polluted waters rich in pesticides. The method for domesticating Daphaera magna of the present invention comprises the following steps:

[0059] 1) Put Daphnia magna into the culture tank, add the toxic substance hexachlorobutadiene to the culture tank, and its maximum concentration is 0.033 μg / L. The concentration of hexachlorobutadiene contained in the culture pool was 0.0099 μg / L, and it was cultivated for 12 hours; Daphnia magna was taken out, placed in a culture pool without adding hexachlorobutadiene, and cultivated for 1 day; the culture pool The bait to be put in can be blue-green algae.

[0060] 2), put the Daphnia magna obtained in step 1) ...

Abstract

The invention discloses a method for domesticating daphnia magna and a water ecological restoration method through the same inventive concept. According to the method for domesticating the daphnia magna, toxic substances are added to a culture pool, and the method for domesticating the daphnia magna is achieved through specific domesticating methods. According to the water ecological restoration method, the daphnia magna domesticated through the toxic substances is adopted and put into water rich in algae and toxic substances such pesticides, therefore, the water is purified, and underwater ecological balance is restored so as to achieve water ecology self-purification.

Description

technical field [0001] The invention relates to two methods for domesticating daphnia daphnia, and two methods for ecological restoration of water bodies, especially a method for ecological restoration of eutrophic water bodies. Background technique [0002] The reason for the outbreak of blue-green algae is that various production activities of human beings discharge nitrogen and phosphorus nutrients 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 water bodies. A large amount of accumulation leads to the flooding of single-celled algae, especially cyanobacteria (mainly Microcystis aeruginosa), which 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 the digestive enzymes ...
