Parallel type circulating water culture container system and usage method thereof

Abstract

A parallel type circulating water culture container system and a usage method thereof belong to the aquatic product culture field, and a high density circulating water culture facility fishery equipment system is provided; the system comprises a culture zone, a backflow duct, a night soil settling zone, and a backflow water zone connecting the culture zone with the backflow duct; the culture zone and the backflow duct are isolated by a film and / or plate type and / or dense net material; the backflow water zone is connected with the culture zone, and water flows in one way in the culture zone; the water reversely flows in the backflow duct, thus forming the one-piece enclosed circulating water culture system; the night soil settling zone settles and gathers night soils on one nearby side of the culture zone, thus transferring night soils with high efficiency. The parallel type circulating water culture container system can reduce circulating pipeline system, can reduce construction fee and operational fee, can gather night soils and residual baits with high efficiency, thus solving aquatic product culture non point source pollution problems, promoting technology progress in culture and sewage processing industry, and improving aquatic product culture equipment level.

Description

technical field [0001] The invention relates to a parallel circulating flowing water culture container system and a method for using the same, belonging to the field of aquaculture, and specifically refers to an isolated culture container system with an upper layer culture area and a lower layer reflux duct for high-density breeding of aquatic animals in the culture area , the excrement settles in time and gathers in the middle feces settlement area, separates from the farmed animals in time, collects the feces and residual bait produced in the aquaculture process, avoids the pollution of the water body by aquaculture, and minimizes the loss of pipelines and the energy consumption of water level difference. Background technique [0002] The global recirculating aquaculture industry has developed rapidly and has become the fastest growing pole in the aquaculture model. It is water-saving, land-saving, and convenient for site selection; water temperature and water quality are c...

AI Technical Summary

Problems solved by technology

The invention can solve the problems of complex structure, large investment and high energy consumption of the circulating aquaculture system, transfer the clean circulating water after the settled feces through the return duct, greatly reduce the energy consumption of the water cycle, and mix a small amount of fecal water with a higher concentration through the pipeline Transportation, return to the aquaculture system after filtration, which reduces energy consumption by about 50-70% compared with conventional land-based industrial recirculating aquaculture systems
