Horizontal three-channel circulating water fish breeding method

Abstract

The invention discloses a horizontal three-channel circulating water fish breeding method. Mainly, natural seawater, underground salt water, underground fresh water and geothermal water are distributed and purified and recycled in a circulating mode, and then an industrialized breeding base for producing pollution-free healthy seafood is established. The method has the advantages that water is supplied to fish breeding pools through water feeding channels, the upper portions of the fish breeding pools, a water pump tank, a water distribution pool, a biofilter, an ultraviolet sterilization pool, a water feeding pool, the water feeding channels and other facilities are all built on the same horizontal plane, and therefore no water level difference is generated, and the lift of a circulating water pump is reduced; the fish breeding pools on two rows in one fish breeding workshop share one circulating water purification facility, and the aims of saving energy, being efficient and reducing cost are achieved.

Description

technical field [0001] The invention belongs to the field of aquaculture industrialization, and in particular relates to a method for raising fish in horizontal three-channel circulating water. It mainly uses natural seawater, underground salt water, underground fresh water and geothermal water to deploy, circulate, purify and reuse, and build an industrial breeding base for the production of pollution-free and healthy seafood. Background technique [0002] Among the disclosed technologies, for example, the application number of the Chinese invention patent is 201310186590.7 "ecological closed circulating water fish farming method", which mainly utilizes the establishment of water storage sedimentation tanks and water distribution workshops near the water intake near the coast; The fish pond and the high-level water supply tank supply water to the fish pond through the branch water pipes drawn from the main water supply pipeline. The high-level water supply tank is 800-1200...

AI Technical Summary

Problems solved by technology

In addition, the present invention also solves the problem that the high-level water supply tank supplies small water to the fish pond through the branch water pipes drawn from the main water supply pipe, and the swirl flow formed is small, which is not conducive to the precipitation and separation of particulate matter in the water in the fish pond and the water in the fish pond If it does not flow, it will not form running water, which is not conducive to the growth of fish, and solve the problem of poor solid-liquid separation effect when the water flow rate is large in the second and third-stage solid-liquid separation tanks
