Breeding device for marine culture

Abstract

The invention discloses a breeding device for marine culture. The breeding device comprises a circulating water culture pond, a vortex solid-liquid separator, a full-automatic backwashing drum mechanical microfiltration machine, a fully-enclosed efficient protein separator, an efficient movable biological filtration tank, a modularized channel type ultraviolet disinfection device and an efficientpure oxygen mixer. The breeding device has the advantages that the circulating water culture pond is designed in a three-way sewage drainage mode, the fully-enclosed efficient protein separator is arranged at the rear end of the full-automatic backwashing drum mechanical microfiltration machine, the position is lowered through civil engineering facilities, water purified by the full-automatic backwashing drum mechanical microfiltration machine flows into the fully-enclosed efficient protein separator, and energy consumption of system operation is greatly reduced; a large-flow ad low-lift circulating water pump is arranged at the rear end of a circulating water culture system, variable-frequency control is achieved, the flow is controllable, and energy consumption is low; the defects of theprior art are overcome, and the novel breeding device is used for marine culture.

Description

technical field [0001] The invention relates to the field of seawater aquaculture, in particular to a culture device for seawater aquaculture. Background technique [0002] At present, the global mariculture industry has entered the period of industrialization development, and the development of industrialized recirculating aquaculture is the only way, and it is the inevitable choice for the mariculture industry to move towards intensification, scale and modernization. At present, there are many kinds of domestic and foreign factory recirculating aquaculture systems, lack of standardization and systematization, and there are a series of problems such as unreasonable design process, large investment in facilities and equipment, and high operating costs, which seriously restrict the promotion and application of domestic recirculating aquaculture. .

Problems solved by technology

At present, there are many kinds of domestic and foreign factory recirculating aquaculture systems, lack of standardization and systematization, and there are a series of problems such as unreasonable design process, large investment in facilities and equipment, and high operating costs, which seriously restrict the promotion and application of domestic recirculating aquaculture.

[0003] In the traditional seawater industrialized recirculating aquaculture system, protein skimmers are often used in China (the effect of protein skimmers in fresh water is very poor), and they are often placed at the back end of microfiltration machines, but they are rarely used in Europe because protein skimmers use at least It needs to be equipped with a lift pump and a jet pump with a large head, which consumes a lot of energy and runs at a high cost

At the same time, the use of a protein skimmer requires a circulating water pump to be installed at the front end of the circulating water system to lift water, and the rear end is self-flowing, which leads to insufficient or uneven flow in the breeding ponds at the far end of the breeding plant
