Breeding box, self-purifying ecological breeding system and breeding method

Abstract

The invention discloses a breeding box, a self-purifying ecological breeding system and a breeding method, and belongs to the technical field of breeding. The breeding box includes a culture tank, a culture sewage discharge tank, a purifying tank and a purification sewage discharge tank which are sequentially separated from the front to the rear by a front blocking mesh piece, a middle separatingpiece and a rear blocking mesh piece. The front side of the culture tank is provided with a diversion cylinder in the vertical direction. The bottom of the diversion cylinder is provided with an aeration and water lifting structure as an inlet of a culture box, and the top of the diversion cylinder is communicated with an inlet on the upper part of the front side of the culture tank; the front ofthe culture tank is provided with a water lifting diversion plate and the lower portion of the water lifting diversion plate is provided with a lower blocking net; aeration pipes are evenly distributed in the purifying tank; the upper portion of the culture sewage discharge tank and the upper portion of the purification sewage discharge tank are provided with sewage discharge diversion plates in the vertical direction, and the bottoms of both the culture sewage discharge tank and the purification sewage discharge tank are provided with blowdown pipes, and the upper portion of the rear side ofthe purification sewage discharge tank is provided with an outlet with an upper blocking net as a water outlet of the culture tank. According to the breeding box, technologies of live water breeding,biological floating bed purification, self-purification of fish, fish polyculture, cultivation of economic crops, and the culture tank having a sewage discharging function and the like are combined.

Description

technical field [0001] The invention belongs to the technical field of breeding, in particular to a breeding box, a self-purifying ecological breeding system and a breeding method, in particular to a breeding box made of cloth, a matching system and a corresponding breeding method. Background technique [0002] China is the world's largest aquaculture country in terms of aquaculture output and aquaculture scale. However, most of the aquaculture farmers in our country aim to pursue output and short-term economic benefits, the breeding density is too high, and the awareness of environmental protection is weak, and the breeding diseases are increasing year by year. At the same time, most of my country's aquaculture is hydrostatic aquaculture, and high-density aquaculture causes a large amount of fish and shrimp excrement, bait and other organic matter to deposit on the bottom of the water. In the peak breeding season, due to high temperature, heterotrophic microorganisms multi...

AI Technical Summary

Problems solved by technology

[0009] (1) The water discharged from the floating tank contains a large amount of phytoplankton and zooplankton, which will consume a large amount of nutrients in the water body and reduce the transparency and oxygen content of the water body. The death of phytoplankton and zooplankton may lead to eutrophication in the water body change;

[0010] (2) In order to ensure the cleanliness of the water body, the floating tank accounts for 8-12% of the water surface, and the economic benefit is low;

[0011] (3) The treatment effect of the sewage collection tank on tiny feces and other sundries is not good, resulting in turbidity of the water out of the floating tank;

[0012] (4) Submerged aquatic plants are not easy to control and manage;

[0013] (5) In order to ensure the quality of the water body, extruded feed is generally used for feeding, but the cost is relatively high
