An intermittent double-circulation industrialized recirculating aquaculture system

Abstract

The invention discloses an intermittent double-circulation industrialized circulating aquaculture system, which is characterized in that it includes a water storage tank, a biofilm reaction tank, a culture tank, and a curved screen. The ponds are connected in series to form a first circulation system, and the cultivation pond and the curved screen are connected in series to form a second circulation system, the first circulation system operates intermittently, and the second circulation system operates continuously. On the one hand, there are fewer accessories, which reduces the initial investment; on the other hand, the first circulation system operates intermittently, and the second circulation system operates continuously. The combination of intermittent operation and continuous operation can increase the concentration of water in the aquaculture pond while ensuring the effect of microbial purification. Sewage, sewage effect This invention is used in the field of circulating aquaculture.

Description

technical field [0001] The invention relates to the field of circulating aquaculture, in particular to an intermittent double-circulation industrialized circulating aquaculture system. Background technique [0002] At present, my country's industrialized recirculating aquaculture industry is booming. However, the traditional industrial circulating aquaculture system generally adopts a series of technical means including microfiltration machine, curved screen, foam separation, ozone disinfection, biological filter, ultraviolet sterilization, heating constant temperature, pure oxygen aeration, etc. , not only caused a large initial equipment investment, but also continued system operation throughout the day also increased production costs. [0003] At the same time, the intermittent operation of the circulating water system has the obvious advantage of lower operating costs, but because the water in the system cannot be circulated, the sewage in the aquaculture pond cannot be...

However, the traditional industrial circulating aquaculture system generally adopts a series of technical means including microfiltration machine, curved screen, foam separation, ozone disinfection, biological filter, ultraviolet sterilization, heating constant temperature, pure oxygen aeration, etc. , not only caused a large initial investment in equipment, but also increased production costs due to continuous system operation throughout the day

[0003] At the same time, the intermittent operation of the circulating water system has the obvious advantage of lower operating costs. However, due to the inability of the water in the system to circulate, the sewage in the aquaculture pond cannot be effectively discharged from the aquaculture environment, causing the water in the aquaculture pond to be turbid.
