Efficient, energy-saving and land-saving factory circulating water high-density breeding system

Abstract

The invention discloses an efficient, energy-saving and land-saving factory circulating water high-density breeding system. The efficient, energy-saving and land-saving factory circulating water high-density breeding system comprises a circulating water breeding pool, a full-automatic back-flushing roller machine filtering machine, a fixed bio-filter bed, an ultraviolet disinfection device, an adjustment pool, an upper movable bio-filter bed, an efficient pure-oxygen mixer, a bio-filter inner-circulation security self-maintenance inoculation-free system and a bypass pipe circulating system. Due to the double bio-filter beds, the purification efficiency can be improved, and the occupied area can be saved. Due to the ultraviolet disinfection device arranged between the double bio-filter beds, efficient disinfection can be achieved, a stable water environment for beneficial microorganism is created for the circulating water breeding pool; due to the bio-filter inner-circulation security self-maintenance inoculation-free system, the stable active biological flora can be kept, and the efficient purification efficiency can be kept; the bypass pipe circulating system can solve the problem caused when medicine is used in circulating water breeding due to the fact that fishes fall ill. The efficient, energy-saving and land-saving factory circulating water high-density breeding system is suitable for high-density breeding of fresh-water and sea-water high-quality varieties.

Description

technical field [0001] The invention relates to the field of industrial circulating aquaculture, in particular to an industrial circulating water high-density aquaculture system with high efficiency, energy saving and land saving. Background technique [0002] Industrialized recirculating aquaculture is to get rid of the constraints of the traditional aquaculture industry by the natural environment. Through physical filtration, biological filtration, water temperature control, ultraviolet sterilization, recycling, online water quality monitoring and remote video monitoring and other technical means, the aquaculture aquatic products are kept in a In a relatively controllable ecological environment, high-density and healthy breeding of seawater and freshwater high-quality aquaculture species is realized, which has the remarkable characteristics of "high yield, high quality, high efficiency, ecology, safety, energy saving and emission reduction". Industrialized recirculating aq...

Problems solved by technology

[0003] The industrialized recirculating aquaculture system is a closed aquaculture model. At present, there are many kinds of industrialized recirculating aquaculture systems developed and applied at home and abroad. There are many researches on its fragments, lack of standardization and systematization, and there are still unreasonable process design, A series of problems such as large investment in facilities and equipment and high operating costs have seriously restricted the promotion and application of domestic recirculating aquaculture
