Integrated circulating water culture system

Abstract

The invention discloses an integrated circulating water culture system which comprises a culture water tank, a foam separation and degassing chamber, a biological active carbon nitration reaction chamber and a low-pressure gas dissolution chamber, and is characterized in that: one part of water from a water drainage structure of the culture water tank is discharged and led into a biological flocculating constituent culture pool from the bottom of the culture water tank, and the other part flows into the foam separation and degassing chamber through an overflow hole at the upper part of the culture water tank; the suspended particles in the culture water are adsorbed by the micro bubbles of the foam separation and degassing chamber and rise to the top of the foam separation and degassing chamber to be discharged out; the culture water flows into the biological active carbon nitration reaction chamber through the foam separation and degassing chamber and is purified by a nitration biomembrane of the biological active carbon nitration reaction chamber and drawn out from the bottom of the biological active carbon nitration reaction chamber; 90% of the culture water drawn out is directly fed into the low-pressure gas dissolution chamber, and 10% of the culture water is fed into a pipeline mixer to mix pure oxygen and ozone and then fed into the low-pressure gas dissolution chamber; and the processed culture water flows back to the culture water tank from a drainage hole at the bottom of the low-pressure gas dissolution chamber.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a circulating aquaculture system integrating a culture water tank, a foam separation and degassing chamber, a biological activated carbon nitrification reaction chamber and a low-pressure dissolved air chamber. Background technique [0002] The recirculating aquaculture system (Racirculating Aquaculture Systems, RAS) is considered to be one of the leading production models representing the development direction of aquaculture in the 21st century because of its advantages of water saving, land saving, and environmental friendliness. The circulating water aquaculture system refers to the physical (solid-liquid separation, foam separation, temperature control, gas-liquid mixing, etc.), chemical (ozone disinfection and oxidation, ultraviolet disinfection, ion exchange, physical and chemical adsorption, etc.), biological (various types of Nitrification / denitrification biological...
