A back-suction flowing water culture system

Abstract

The invention discloses a rear suction type running water aquaculture system and a method for applying the same, and belongs to the field of aquaculture. The rear suction type running water aquaculture system comprises an aquaculture container body, a dirt gathering container, a flow promoting power device and a frame support structure which are dependent on one another. The integrated novel circulating running water high-density and low-power aquaculture system is integrally of an approximately flat-bottom hexahedron structure, and a side of the section of a water inlet is isolated by grid materials, so that the areas can be enlarged, the flow rates can be reduced, and damage and loss due to against-current and stress response of aquatic products can be reduced; the bottom surface of the dirt gathering container is lower than that of the aquaculture container body, accordingly, the rear suction type running water aquaculture system is favorable for efficiently settling feces and efficiently removing the feces, and pollution of water due to aquaculture can be reduced; low-lift and high-through-flow water change power can be provided by the flow promoting power device, so that the water inside and outside the aquaculture system can be efficiently circulated, and oxygen required by the aquatic products in the aquaculture system can be efficiently supplemented. The rear suction type running water aquaculture system and the method have the advantages that the rear suction type running water aquaculture system and the method are applicable to the field of aquaculture, the field of biological purification of micro-polluted water and the field of quality purification and enhancement of aquatic products, the difficult problem of non-point source pollution of aquaculture can be solved, the unit-area yield can be greatly increased, and the quality of the aquatic products can be enhanced.

Description

technical field [0001] The present invention relates to a running water aquaculture system and its use method, specifically a back-suction flow water aquaculture system arranged on the surface of a water body and its use method. Aquatic animals are raised in high density in the aquaculture system, and the power system for promoting water body exchange is located at The back end of the flowing water aquaculture system reduces the impact of relatively rapid water on the aquaculture organisms, is conducive to collecting the feces and residual bait produced by aquaculture itself, and avoids the pollution of aquaculture to the water body. Background technique [0002] With the continuous increase of pond breeding density, a large amount of feces and residual bait pollute the pond water body, and untreated aquaculture sewage is discharged into rivers and lakes, becoming a source of pollution for very scarce water resources. Reducing non-point source pollution from aquaculture has ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems that the water flow in the cultured waters of a water-based flowing water culture container is relatively rapid when it is installed and used, the cultured organisms are frequently topped with water, the scratches and bruises cause serious losses, and affect the feeding and growth of the cultured organisms, etc. Specially developed back-suction flowing water aquaculture system with slow water inflow and fast concentrated water outflow and its application method
