Problems solved by technology

[0006] The recirculating aquaculture system is a closed system. The system can use antibiotics scientifically and precisely according to the needs of the animals, but the antibiotics left in the system need to be removed quickly, otherwise it will affect the functional bacterial activity of the water treatment unit of the recirculation system, making the The water treatment capacity of the biological filter is reduced, which leads to the deterioration of the water quality of the whole system
At present, there is still a lack of effective technical methods that can quickly remove residual antibiotics in recirculating aquaculture systems

Abstract

The invention relates to a circulating aquaculture system capable of rapidly removing residual antibiotics, comprising a culture unit (1), a mechanical filtration unit (2), an ultraviolet photolysis unit (3), an adsorption-biodegradation unit (4) and a water treatment unit (5); Among them, each unit is connected to each other to form the antibiotic medication circulation subsystem (P1) of the culture unit; the residual antibiotic ultraviolet photolysis circulation subsystem (P2); the residual antibiotic adsorption-biodegradation circulation subsystem (P3) and the system circulation culture Circulatory subsystem (P4). Compared with the prior art, the invention can realize the scientific drug use of antibiotics in the circulating aquaculture system and realize the effective removal of residual antibiotics, and has obvious economic and environmental benefits.

Description

technical field [0001] The invention relates to an aquaculture environment protection technology, in particular to a circulating aquaculture system capable of rapidly removing residual antibiotics. Background technique [0002] The global aquaculture industry is developing rapidly, and my country accounts for more than 60% of the global aquaculture production. Aquaculture waters include fresh water, sea water, and salt water. Aquaculture types include pond culture, lake seine culture, tidal flat culture, shallow sea and deep sea cage culture, etc., and farming models include extensive, semi-intensive and industrial farming. Wait. Industrial aquaculture, also known as Recirculating Aquaculture System (RAS for short), is the main development direction of aquaculture industry. It comprehensively uses advanced technology and industrialized means to control the living environment of aquaculture organisms and conduct scientific management, so as to get rid of land It is a high-d...
