Shallow-water three-dimensional multi-layer intensive high-density aquaculture system

Abstract

The invention provides a shallow-water three-dimensional multi-layer intensive high-density aquaculture system which comprises multiple layers of shallow-water aquaculture tanks arranged up and down, a water injection pipeline, double-layer drainage pipes and water treatment integrated equipment, wherein the water injection pipeline is arranged above the shallow-water aquaculture tank on the uppermost layer and used for controlling the water injection amount; a water inlet and a water outlet of each layer of shallow-water aquaculture tank are located in the diagonal direction of the aquaculture tank, and one double-layer drainage pipe is arranged in each layer of shallow-water aquaculture tank; and the lowest layer of shallow-water aquaculture tank is connected with the water treatment integrated equipment, and the water treatment integrated equipment is used for purifying sewage discharged from the upper part. By adopting a self-circulation drainage mode from top to bottom, combining devices such as the double-layer drainage pipes, an unpowered dissolved oxygen supercharger and a residue separator and cooperating with water treatment integrated equipment, the water dissolved oxygen amount can be increased, the water quality can be improved, diseases can be reduced, effects of no emission, no pollution, no chemical and no antibiotic can be achieved, and the formed product is green, safe, ecological and environmentally friendly.

Description

technical field [0001] The invention relates to a multi-level aquaculture system, in particular to a shallow-water three-dimensional multi-layer intensive high-density aquaculture system. Background technique [0002] China's shrimp farming industry has faced serious sustainable development problems in recent years. In some areas, the disease is serious and has a tendency to spread; in some areas, the growth of prawns is stagnant at certain times, resulting in failure or even loss of farming. [0003] At present, there are 6 modes commonly used in domestic traditional farming, as follows: [0004] 1) Extensive cultivation mode in soil ponds; [0005] 2) Earth pond culture mode; [0006] 3) Pond semi-intensive culture mode; [0007] 4) Segmented high level pond intensive cultivation mode; [0008] 5) Fish and shrimp polyculture mode; [0009] 6) Industrial high level pond culture mode. [0010] The above 6 models have higher yields in the segmented high-level pond inte...

Problems solved by technology

[0017] The purpose of the present invention is to provide a shallow-water three-dimensional multi-layer intensive high-density culture system, which can solve the waste of water resources, waste of land resources, environmental pollution, high maintenance cost, and cross-source of disease caused by the existing intensive culture mode of shrimp culture. At the same time, it also solves the technical problems of insufficient water-soluble oxygen in the process of the existing indoor multi-level aquaculture mode, and the slow growth of sea white shrimp under the influence of light, the decrease of survival rate and the indoor noise pollution of the factory
