Problems solved by technology

However, the water body of existing wild lakes is rich in toxic substances and harmful substances such as toxic blue-green algae, and the temperature is high in summer. Unaccustomed water fleas ingest algae and algae and The ability to survive is obviously reduced, and it is difficult to survive stably for a long time, which greatly limits the application of daphnia in water ecological restoration.

Embodiment 1

[0029] The water flea temperature-resistant domestication method of the present embodiment specifically comprises the following steps:

[0030] A: Collect some water fleas (Cladocera) in the wild;

[0031] B: Place water fleas in the first culture pool and the second culture pool (there is culture fluid in the culture pool) for cross-acclimation culture, the initial temperature of the culture fluid in the two culture pools is 18°C, and the The temperature of the culture medium was kept constant;

[0032] Specifically:

[0033] B1: First, put water fleas into the first culture pool, the stocking density is 200-500 per liter of water, and domesticate and cultivate for 8 hours;

[0034] B2: Take out the daphnia, place it in the second culture tank, and cultivate it for 8 hours;

[0035] B3: Increase the temperature of the culture solution in the first culture tank by 1°C, then take out the daphnia and put it into the first culture tank, and acclimatize and cultivate for 8 hour...

Abstract

The invention aims at providing a temperature resistance domestication method for daphnia and a method for conducting ecological repair on a water body through daphnia. The method includes the steps that A, daphnia is placed in a breeding solution to be bred for a set period of time, and the temperature of the breeding solution is changed into the preset temperature according to the same tendency; B, the step A is repeatedly executed till the temperature of the breeding solution reaches the preset limiting temperature, beneficial microorganisms are put in, and domestication of daphnia is completed. By putting daphnia domesticated according to the method in the water body rich in toxic substances and algae, the water body can be purified, the underwater ecological balance can be repaired, and the ecological self-purification of the water body can be achieved.

Description

technical field [0001] The invention belongs to the fields of environmental protection and biotechnology, and in particular relates to a water flea temperature-resistant domestication method and a method for ecological restoration of nutrient-rich water bodies by using the water flea. 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 har...
