Problems solved by technology

[0002] Most of the existing circulating aquaculture systems are equipped with a dozen or even dozens of ponds, including aquaculture ponds for different fish cultures, and equipment ponds for water quality treatment. Dozens of aquaculture ponds need to be arranged in the workshop , the passage between the pools must be reserved, resulting in a very large area and low space utilization. With the gradual increase of land prices, the cost of renting or purchasing the site will be very high
Moreover, the arrangement and installation of the inlet and outlet pipelines equipped with dozens of breeding ponds is complicated, so that the maintenance of the pipelines will consume a lot of manpower. At the same time, the daily maintenance and cleaning of the breeding ponds also need to consume a lot of manpower. Need a lot of labor

Abstract

The invention relates to a recirculating aquaculture system with a large annular aquaculture pond as a core and belongs to the field of fish aquaculture ponds. The recirculating aquaculture system comprises an aquaculture pond A and an aquaculture pond B which are connected in an internally-externally sleeved mode, wherein a physical filtering pond is arranged on the outer side of the aquaculture pond A, water draining ports are formed in the side faces and the bottoms of the aquaculture pond A and the aquaculture pond B and are connected to the physical filtering pond, a biological filtering pond is arranged in the aquaculture pond B, the physical filtering pond is connected to the biological filtering pond, an anaerobic denitrification reaction pond is connected in the biological filtering pond and is connected to an ultraviolet light sterilization device on the outer side of the aquaculture pond A, the water outlet end of the ultraviolet light sterilization device is connected to an aeration tank, the water outlet end of the aeration tank is connected to a water-mixing pond, water in the water-mixing pond is oxygenated, and the water outlet end of the water-mixing pond is connected to an impeller pump pond. The floor area can be effectively decreased, the space utilization rate can be improved, and the number and sizes of independent spaces in the pond can be flexibly adjusted.
