A diseased fish in one pond can quickly spread to fish in others. This application utilizes an independent aquaculture system to prevent cross-infection of pathogens between fish. The independent aquaculture system eliminates cross-contamination between ponds, offering the advantages and advantages of preventing pathogen cross-contamination. The elliptical structure also allows for better site utilization, optimized structure, and increased processing capacity. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this application adopts the following elliptical circulation ecological farming system structure, which can greatly improve water treatment efficiency and reduce cross infection.

A drainage grate is provided between the bottom of the elliptical ring water area (1) and the water inlet of the circular vertical flow sedimentation tank (2). The fish excrement in the water passes through the drainage grate at the bottom of the elliptical ring water pool (1) by gravity and enters the circular vertical flow sedimentation tank (2); the upper and middle clear water outlets of each circular vertical flow sedimentation tank (2) are connected to a drum filter (3). The water inlet of the drum filter (3) is connected, the water outlet of each drum filter (3) is connected to a water storage tank (6) via a respective pipeline, an ultraviolet disinfection lamp (4) is provided in the corresponding pipeline in front of each water storage tank (6), a biological filter bag (5) is provided behind the ultraviolet disinfection lamp (4) or at the outlet end of the pipeline, each water storage tank (6) is provided with a water pump (7), and the water outlet of each water pump (7) is connected to the elliptical ring water tank (1); the water storage tank (6) is also provided with an oxygenation port and a new water injection port.

[0006] The structure of the circular vertical flow sedimentation tank (2) is as follows: the overall appearance is vertical cylindrical, the bottom is conical, a sewage outlet (2-1) is provided at the bottom of the cone to connect to the sewage pipe for discharge, a radial water inlet pipe (2-2) is provided at the intersection of the cone and the cylinder, and a vertical upward central pipe (2-4) is provided in the middle of the cylinder, and the radial water inlet pipe (2-2) is connected to the lower end of the central pipe (2-4); a sleeve (2-3) is coaxially provided on the outside of the central pipe (2-4), and a gap is provided between the central pipe (2-4) and the sleeve (2-3); An overflow collar (2-5) is provided at the upper end of the sleeve (2-3); the overflow collar (2-5) comprises an annular bottom and an overflow barrel plate coaxially and perpendicular to the annular bottom; the bottom surface of the overflow barrel plate is the annular bottom; the outer periphery of the center hole of the annular bottom is provided with at least one circle of small holes; the sleeve (2-3) passes through the center hole of the annular bottom; the diameter of the center 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; the upper end of the overflow barrel plate is provided with a toothed edge; the side surface of the vertical cylinder is provided with a water outlet (2-6). 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).

[0007] The operation process of this application is as follows: when water purification is needed, if there is water in the water storage tank (6), the water pump is turned on so that the water enters the elliptical annular water tank (1) under the action of the water pump. The water at the bottom of the elliptical annular water tank (1) enters the circular vertical flow sedimentation tank (2) for treatment, then enters the drum filter (3) to remove suspended particles, and then enters the pipeline. In the pipeline, most bacteria and viruses are killed by ultraviolet disinfection lamps, and then ammonia nitrogen and nitrite are removed by biological filter bags to complete the purification of aquaculture water. The purified water enters the water storage tank (6) and enters the elliptical annular water tank again through the water pump for aquaculture use (1). The two water treatment systems can be operated separately or simultaneously.

[0008] The advantage of this system is that it uses the principles of fluid mechanics to effectively remove large and small aquaculture waste particles and water-soluble pollution factors in the water through various water treatment links, so that the aquaculture water body is fully purified. At the same time, it has the characteristics of saving water resources, occupying a small area, and effectively controlling the spread of fish diseases. BRIEF DESCRIPTION OF THE DRAWINGS
