Description
Technical Field
The invention relates to the technical field of snakehead culture, in particular to a snakehead circulating water purification culture system.
Background
Snakehead is a common name of snakehead [ l ǐ ], also named snakehead, raw fish, fistular fish, snakehead fish and the like.
The snakehead is violently born, strong in reproductive capacity and unusually large in appetite, all other fishes in a certain lake or pond can be eaten, and the snakehead can slide on the land and migrate to other water areas to look for food, so that the snakehead can live 3 days away from water. As early as two thousand years ago, the Chinese herbal medicine is listed as the superior product of the insect fish by being mixed with the stone honey, the bee larva, the beeswax, the oyster, the tortoise shell, the ixora, the sea clam, the hard clam, the carp and the like. Snakehead is a common edible fish in China, and has the advantages of large individual, fast growth and high economic value. The snakehead has less bony spur, high meat content and rich nutrition, and has higher protein content than chicken and beef. The snakehead has the effects of removing blood stasis, promoting tissue regeneration, nourishing, recuperating and the like as a medicine, and after surgical operation, the edible snakehead has the effects of promoting tissue regeneration, enriching blood and promoting wound healing and has very rich nutritional value.
In the traditional snakehead culture process, if a traditional extensive culture mode is adopted, namely natural water is utilized for natural culture, waste materials, waste baits and the like are dissolved in the water, fish feces are deposited in bottom mud, the culture water is easy to form eutrophication, fishes are easy to get ill, and water needs to be changed, so that pollution is caused, the polluted culture water is discharged to other places, so that a large amount of water resources are wasted, and a large amount of biological metabolites, residual baits and the like are generated in the aquaculture process, so that the biological metabolites and the residual baits cannot be well utilized, and the environment pollution is caused by the direct discharge of culture wastewater; the factors such as culture temperature, water quality and the like can not be effectively controlled, the scientific management of aquaculture is lacked, the culture period is long, and the culture benefit is low.
At present, although a snakehead circulating water purification culture mode also exists, a large amount of waste materials, waste baits and other residues exist in polluted culture water, the polluted culture water cannot be discharged at one time in the purification process, the filter water or the filter material is discharged through a sewage discharge pipe, after the purification water is used for a period of time, intercepted pollutants are accumulated to cause the blockage of the filter element or the filter material, the water quality and the water yield can be reduced, in this case, if the filter element or the filter material is not replaced in time, the pollution to the water is aggravated, negative effects are caused, sometimes, the water cannot be discharged, and if the filter element or the filter material is frequently replaced, the purification water is very troublesome.
Therefore, a set of snakehead circulating water purification culture system is researched, water conservation, high-density intensification and waste-free discharge are realized, the snakehead survival rate can be improved, the culture period is shortened, the waste water discharge is controllable, and the system is a major breakthrough in the snakehead culture industry.
