Water supply system for factory circulating water breeding of sturgeons

Abstract

The invention discloses a water supply system for factory circulating water breeding of sturgeons. Breeding ponds are involved; the water supply system of the breeding ponds comprises a constant flowing water supply system body and a circulating water supply system body which are automatically switched for water supply, and the circulating water supply system comprises following units including aphysical filtering unit, a degassing unit, a biological purification unit, an aeration unit, a sterilization unit and a temperature control unit; the physical filtering unit is communicated with the breeding ponds; the degassing unit is arranged at the rear portion of the physical filtering unit system; the biological purification unit is arranged at the rear portion of the degassing unit system;the aeration unit is arranged at the rear portion of the biological purification unit system and communicated with the breeding ponds; the sterilization unit is communicated with the physical filtering unit and the biological purification unit separately; the temperature control unit is communicated with the biological purification unit. According to the water supply system, two automatically switched water supply system bodies are adopted, the purposes of high breeding density of sturgeon varieties, low running energy consumption and stable and efficient running can be achieved, and thereforethe sturgeons are in a relatively controllable ecological environment.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and more specifically relates to a water supply system for industrialized recirculating aquaculture of sturgeon. Background technique [0002] As a modern intensive aquaculture model, the recirculating aquaculture system already has the advantages of high breeding density, no seasonal restrictions, water and land saving, and controllable environment. In Europe, high-density closed recirculating aquaculture has become a rapidly developing technology-intensive industry. At present, various aquaculture powers in the world are conducting key researches on the ecological engineering of recirculating aquaculture, water circulation equipment, compound planting, separation and strengthening and other high-efficiency aquaculture models, as well as corresponding facilities, mechanization, and information technology and equipment. my country's recirculating aquaculture research started relatively late....

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the water supply of sturgeon in factory culture, adopts two sets of water supply systems that can be switched each other, and various technical means such as water temperature control, biological purification, sterilization and disinfection, etc., so that the breeding objects are in a relatively controllable ecological environment, Solve the breeding of sturgeon broodstock and the seasonal production of caviar due to its biological characteristics, and realize the annual production and supply of sturgeon fry and caviar products.
