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.
