Shipborne circulating aquaculture system

Abstract

The invention provides a shipborne circulating aquaculture system. The shipborne circulating aquaculture system comprises a plurality of aquaculture tanks and a plurality of circulating water treatment systems cooperating with the aquaculture tanks, wherein the four end corners of each aquaculture tank are provided with water inlet ports respectively, the water inlet ports are connected with waterinlet pipes, and the water inlet pipes are connected with a water inlet main pipe; the center of the bottom of each aquaculture tank is provided with a water outlet port, and the water outlet port isconnected with a water outlet pipe provided with two water outlet passages; each circulating water treatment system comprises a biological filter, a CO2 remover, an ultraviolet ray sterilizer, oxygenation cones, circulating pumps and a water collecting tank; each water collecting tank allows the corresponding circulating pumps to pump water, the number of the corresponding circulating pumps is two, an outlet of one of the circulating pumps is connected with inlets of the corresponding oxygenation cones, and outlets of the corresponding oxygenation cones are connected to the water inlet main pipe; an outlet of the other circulating pump is connected to the water inlet main pipe. The shipborne circulating aquaculture system has the advantages that the structure is compact, the system is suitable for a shipborne environment, the volume use ratio is high, and the circulating water treatment systems are adopted for keeping the water environments in the aquaculture tanks in a good range allthe time.

Description

Technical field [0001] The invention relates to an aquaculture system, in particular to a ship-borne circulating aquaculture system. Background technique [0002] The key to the development of deep sea aquaculture is safe and reliable facilities and equipment. Our company has developed a recirculating aquaculture cabin with perfect circulating water system functions for deep sea aquaculture ships, which is suitable for high-density economic fish. Farming. [0003] Land-based industrialized circulating aquaculture facilities have been widely used in Norway, Denmark and other places. In general, land-based industrial circulating aquaculture facilities have the following characteristics: the breeding ponds and the circulating water treatment system are arranged separately; the depth to diameter ratio of the breeding ponds is about 1:3-1:5, and the breeding ponds are flat; single breeding The volume of the pond is small, and multiple breeding ponds share a circulating water treatme...

AI Technical Summary

Problems solved by technology

Generally speaking, because the available area for land-based construction is more abundant, the average aquaculture volume per unit area of ​​land-based industrialized recirculating aquaculture facilities is relatively low, about 1.2m 3 / m 2 , the total area is larger
