Circulating water aquaculture system based on advanced oxidation technology

Abstract

The invention discloses a circulating water aquaculture system based on the advanced oxidation technology. The system is mainly composed of a mechanical micro-filter, a protein separator, a liquid-liquid mixer, a gas-liquid separator, a membrane bioreactor, a channel type ultraviolet sterilizer, an air compressor, an oxygen generator, a hydroxyl radical generator, a Venturi jet device and a culture pond. The culture pond is connected with the mechanical micro-filter, the mechanical micro-filter is connected with the protein separator, the protein separator is communicated with the liquid-liquid mixer, the hydroxyl radical generator is communicated with the liquid-liquid mixer through the Venturi jet device, the liquid-liquid mixer is connected with the membrane bioreactor through the gas-liquid separator, and the membrane bioreactor is connected with the culture pond through the channel type ultraviolet sterilizer. The system has the advantages that water in the offshore continental rise culture pond can be recycled, and the pollution-free, healthy and environment-friendly culture effects of saving water, saving energy and achieving environmental friendliness are achieved.

Description

technical field [0001] The invention relates to a factory-like circulating aquaculture system, in particular to a circulating aquaculture system based on advanced oxidation technology. Background technique [0002] Recirculating aquaculture is also known as closed system aquaculture, and its main feature is that the water discharged from the aquaculture pond is recycled and reused. The circulating water treatment process generally includes: sedimentation, filtration, biological purification, oxygenation, temperature adjustment, sterilization and disinfection, etc., and then enter the culture pond water for recycling. The recirculating aquaculture model has a small footprint, high breeding density, water-saving, energy-saving, and high-efficiency; it can regulate all aspects of aquaculture production, and can achieve drug-free production. It is a sustainable and healthy farming model. Closed recirculating aquaculture technology integrates engineering technology, biotechnolog...
