Circulating aquaculture system

Abstract

The invention discloses a recirculating aquaculture system. The system comprises an aquaculture system and a circulating water treatment system. The aquaculture system comprises at least two culture ponds, the circulating water treatment system comprises a dirt collecting tank and a treatment system; the dirt collecting tank comprises a first dirt collecting tank and a second dirt collecting tank;the culture ponds are respectively communicated with the first dirt collecting tank and the second dirt collecting tank through culture pond blow-off pipes; the sewage sequentially flows to the sewage collecting tank and the treatment system from the culture ponds and then flows back to the culture ponds; water inlet pipes for discharging sewage into the treatment system are respectively arrangedbetween the first sewage collection tank and the treatment system and between the second sewage collection tank and the treatment system. The circulating water culture system is capable of preventingharmful substance-containing water in a certain culture pond from entering a water circulation treatment system to generate adverse effects on a biochemical system and other healthy culture ponds.

Description

technical field [0001] The invention relates to the technical field of aquaculture equipment, in particular to a circulating aquaculture system. Background technique [0002] With the development of the aquaculture industry, new aquaculture models such as high-level ponds, industrial aquaculture, land-based push water, and recirculating aquaculture continue to emerge. High-density, high-yield, and high-quality have become the focus and difficulty of aquaculture development. No matter what kind of aquaculture mode is adopted, farmers can adjust water quality and prevent pests and diseases by putting fish fry and feed, as well as microbial agents, sterilizing insecticides, and oxygenation into the aquaculture ponds, so as to achieve high aquaculture output. . However, in the production process of aquatic products, feed residues, excreta from aquatic products and other wastes in the breeding ponds continue to increase. If these pollutants are not discharged from the ponds in t...

AI Technical Summary

Problems solved by technology

Such a circulating breeding system needs to excavate the earthwork for construction and pipe layout, which not only increases the amount of engineering and construction difficulty, but also makes it difficult to carry out leak detection and maintenance work on the buried pool body and buried pipes in the future

At the same time, in order to reduce the accumulation of breeding waste in the breeding ponds and sedimentation tanks, it is necessary to regularly discharge and rinse the breeding ponds and sedimentation tanks. All the water is drained away, so that people can enter the pool for cleaning, which causes a large amount of water exchange in the system, wastes water resources, and consumes a lot of manpower and material resources for cleaning
