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 present invention discloses two methods for domesticating a large flea and a water body ecological restoration method with the same inventive concept. The water body ecological restoration method is to use the large flea after domestication of toxic substances, and put it into the water body rich in toxic substances such as pesticides and algae, so as to purify the water body, restore the underwater ecological balance, and achieve the ecological self-purification of the water body.

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 ...
