Embodiment 1
[0045] In the prior art, the water treatment process of centralized and decentralized farming is as follows: figure 1 . The decentralized water treatment process is that the water in a single fish pond is pumped out, and then returned to the fish pond after successively undergoing physical filtration, biological filtration, degassing, sterilization and oxygenation.
[0046] The centralized water treatment process is: the water in multiple fish ponds (fish ponds I, II, II) is pumped out and collected together, and then returned to each fish pond after successively undergoing physical filtration, biological filtration, degassing, sterilization and oxygenation.
[0047] Inner circulation fishpond of the present invention is:
[0048] Such as image 3 As shown, the structure of the inner circulation fish pond (fish pond I) includes a central fish pond 15. The shape of the central fish pond is an octagon with four cut corners. , the long side of the outer wall b, the short side ...
Embodiment 2
[0067] Such as Image 6 As shown, the central fish pond is a circle, and the rectangle circumscribed by the central fish pond has four corners. A sedimentation system is set on one of the corners, and the structure and working principle of the sedimentation system are the same as those in Embodiment 1.
[0068] An internal circulation system is set on the remaining three corners, and the structure and working principle of the internal circulation system are the same as in Embodiment 1.
