The bottom surface of the overflow barrel plate is the annular bottom. At least one circle of small holes is arranged on the outer periphery of the central hole of the annular bottom. The sleeve (2-3) passes through the central hole of the annular bottom, and the diameter of the central hole is equal to the outer diameter of the sleeve (2-3). The diameter of the overflow barrel plate is smaller than the inner diameter of the vertical cylinder. A toothed edge opening is arranged at the upper port of the overflow barrel plate; a water outlet (2-6) is arranged on the side surface of the vertical cylinder. At the same time, the physical position of the water outlet (2-6) is higher than the physical position of the radial water inlet pipe (2-2).

[0022] The working principle of the vertical flow sedimentation tank (2) is to utilize the natural law that water flows to lower places or the principle of a communicating pipe, so that the water discharged from the aquaculture fishpond (1) enters through the radial water inlet pipe (2-2) and then goes up along the central pipe (2-4), comes out from the upper port of the central pipe (2-4), and then spreads around.

The fish pond fecal sewage is filtered by the fine filler and the coarse filler and is decomposed by microorganisms into nutrients that can be absorbed by plants. Among them, coarse filler is used around the siphon drainage system (5), and fine filler is used in other parts; the above-mentioned fine and coarse are relative and can be determined according to the punching aperture of the drainage cover.

[0025] The water between the reservoir (4) and the aquaculture fish pond (1) flows by physical natural water flow or a pump.

[0028] The fish pond, the vertical flow sedimentation tank, the mineral matrix planting bed, and the hydroponic floating plate planting bed are combined to reduce the energy consumption of the system by improving the sewage interception capacity and tidal drainage capacity of the planting bed; during the operation of the system, an aerobic environment and an anaerobic environment are formed during the process of the planting bed being in the emptied state and the full water state, effectively improving the decomposition and conversion of microorganisms in the planting bed and the safety guarantee of aquaculture.

[0029] By establishing a courtyard-style aquaponics circular planting system, the excrement and sewage of farmed fish are utilized. After passing through a vertical flow sedimentation tank, large particulate fish feces are precipitated and collected. Then, the water body rich in nutrients enters the mineral substrate bed. The water body nutrients and fine particulate matter are adsorbed by the mineral substrate and, after being decomposed and transformed by microorganisms, form nitrates that can be absorbed by plants. The purified water body is quickly discharged to the reservoir through a self-regulating siphon drainage device, and the water body is transported to the aquaculture system through a water pump, thus forming a stable planting and aquaculture circular system.
