It has the advantages of small footprint, convenience and quickness and simple operation.

The use process of the present utility model is as follows:

As shown in Figure 4, the external water source first flows into the ultraviolet sterilization tank 1 of the water treatment system. After being sterilized by the ultraviolet sterilizer in the ultraviolet sterilization tank 1, it flows to the ozone disinfection tank 2. After being sterilized by the ozone generated by the ozone machine, it passes through the shaft. The flow pump 31 raises the water level (the flow rate of the axial flow pump 31 is adjustable), enters the aeration tank 3, is oxygenated and removes carbon dioxide and ozone, and then enters the annular culture tank 4 through the tangential line of the water outlet slit 32, and drives the water body in the pool to flow, and the water outlet slit A fishing net is set outside 32 to prevent fish in the breeding pond from entering the water treatment system.

The residual bait and excrement at the bottom of the annular breeding pond 4, due to the slope of the bottom of the pond and the scouring of the water flow, gather into the V-shaped sewage collection tank. The structure is like a funnel, the edge is high and the middle is low. The upper part of the tank is equipped with a horizontal fish trap 42, which only allows the passage of residual bait and feces, preventing the fish from being sucked away by the plugging and unplugging sewage pipes at the bottom. The plugging and unplugging sewage casing 43 is a sewage discharge pipe pre-buried at the bottom of the pool. The pipe consists of the bottom horizontal buried pipe, the 90° elbow casing, and the vertical plugging and unplugging pipe. The sewage outlet can be opened by pulling out the pipe, and the sewage or emptying of the breeding pond can be completed, avoiding the disadvantages of installing the valve underground and opening and closing the valve by personnel going down to the maintenance well.

Drainage from the annular culture pond 4 flows out tangentially through the backwater slit 33 and enters the water treatment system. A fish net is arranged outside the backwater slit 33 to prevent fish in the aquaculture pond from entering the water treatment system.

After the drainage enters the return tank 10 through the return seam 33, it operates in three ways under different working conditions:

(1) Under normal working conditions, the drainage first enters the microfilter pool 5, and the microfilter filters the large particles of residual bait feces, and then enters the first, second, and third biological pools in turn through the gate to complete the purification of microorganisms, and finally enters Ultraviolet sterilization tank 1;

(2) When the microfiltration machine is damaged, the drainage of the breeding pond directly enters the first, second and third biological pools to complete the purification of microorganisms, and finally enters the ultraviolet sterilization tank 1, and the temporary treatment of the water treatment system ensures that the breeding system is short-term. ensure the survival of fish first, and at the same time reserve time for the maintenance of the microfiltration machine;

(3) When cleaning and overhauling the microfilter and the biological pool, the drainage directly enters the ultraviolet sterilization pool 1 through the overflow channel 9, and the water flow of the annular culture pool 4 is preferentially guaranteed.

A total of two sets of rotationally symmetric water treatment systems are provided in the middle of the annular cultivation pond 4. When high-density cultivation is used, two sets of water treatment systems are used. When the cultivation density is low, one set of water treatment systems is used to save energy and reduce consumption; the utility model is not only common in cultivation. Fish, more suitable for breeding cold-water fish, such as rainbow trout, Atlantic salmon, etc.; runway-type aquaculture ponds are also suitable for shrimp farming, and the effect is obvious.

The utility model can be widely used in aquaculture occasions.
