Circulation aquaculture process and system

Abstract

The invention discloses a circulation aquaculture process and system. The aquaculture system includes a breeding unit, a filtering unit, a biological reaction unit, a degassing unit, a plant cleaning unit, an oxygenation disinfection unit, a water feeding and drainage unit, and an intelligent control unit; the breeding unit, the filtering unit, the biological reaction unit, the degassing unit, the plant cleaning unit, and the oxygenation disinfection unit are successively connected through a pipe of the water feeding and drainage unit to form a circulation system. The beneficial effects of the invention are that the micro-nano bubble aeration technology has a good oxygenation effect, and can improve the biological activity of cells and the breeding density; micro-nano ozone bubbles and ultraviolet light can improve the disinfection effect, can reduce chemicals, and can ensure food safety; water feeding and drainage, temperature control, pH control, oxygenation, disinfection and feeding can be achieved automatically, and labors can be saved; processed waste water can be used for watering or enter to the system to be used; sludge becomes an organic fertilizer, a closed ecological chain is formed, and zero emission, a water saving, energy saving, and environment protection effect can be achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a circulating aquaculture process and system. Background technique [0002] In order to improve production efficiency and realize environmental protection, a recirculating aquaculture system has emerged as the times require. The main processes include mechanical filtration, biological treatment, oxygenation, disinfection, etc. The application of domestic intelligent control is not high, and the application of mechanical equipment in the process is not ideal. When the water quality is not well controlled, drug control is often used, which makes the drug residue exceed the standard and causes food safety problems. Most of the world adopts intelligent control, and the entire process is mechanized. When it is introduced into domestic use, in addition to high equipment investment and operating costs, the management cost is also high; some processes also combine hydroponics to produce vegeta...

AI Technical Summary

Problems solved by technology

The application of domestic intelligent control is not high, and the application of mechanical equipment in the process is not ideal. When the water quality is not well controlled, drug control is often used, which makes the drug residue exceed the standard and causes food safety problems.

Most of the world adopts intelligent control, and the entire process is fully mechanized. When it is introduced into domestic use, in addition to high equipment investment and operating costs, the management cost is also high; some processes also combine hydroponics to produce vegetables, but the domestic market cannot reach the corresponding level The sales price cannot be well promoted and applied
