Description

Technical Field

[0001] This utility model relates to the field of high-density aquaculture, specifically a high-density aquaculture system. Background Technology

[0002] High-density aquaculture is a technology model that achieves high-yield aquaculture in limited water areas through intensive methods. Its core lies in breaking through the density limitations of traditional aquaculture by optimizing environmental control, feed management, and disease prevention.

[0003] However, most traditional high-density aquaculture systems have simple layouts and single functions, making it impossible to remove uneaten feed, feces and other organic matter in a timely manner. This leads to the accumulation of ammonia nitrogen and nitrite, and the lack of attachment carriers for beneficial microorganisms such as nitrifying bacteria (such as biological filters) hinders nitrogen cycling, making water quality prone to deterioration. Furthermore, relying solely on sedimentation tanks or simple screens cannot efficiently remove small particles (such as suspended feed debris), increasing water turbidity. Utility Model Content

[0004] To address the shortcomings of existing technologies, most traditional high-density aquaculture systems have simple layouts and limited functions, making it difficult to remove uneaten feed, feces, and other organic matter in a timely manner. This leads to the accumulation of ammonia nitrogen and nitrite, a lack of attachment carriers for beneficial microorganisms such as nitrifying bacteria, obstructed nitrogen cycling, and easy deterioration of water quality. This invention proposes a high-density aquaculture system.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-density aquaculture system, including multiple fish ponds, each fish pond having a fish toilet fixedly installed in its inner cavity, the bottoms of the fish toilets being fixedly connected to a first sewage pipe, the other end of the first sewage pipe being fixedly connected to a first water pump, the output end of the first water pump being equipped with a microfilter, the output end of the microfilter being fixedly connected to an ozone generator, the output end of the ozone generator being fixedly connected to a biochemical disinfection tank, the output end of the biochemical disinfection tank being fixedly connected to a second water pump, and the output end of the second water pump being fixedly connected to a water storage tower.

[0006] Preferably, there are several water storage towers, and the several water storage towers are fixedly connected by a connecting pipe, and a water supply pipe is fixedly connected to the surface of one of the water storage towers.

[0007] Preferably, the surface of the water supply pipe is fixedly connected to an aeration pipe, and the number of aeration pipes is several, with the several aeration pipes respectively set on one side of several fish ponds.

[0008] Preferably, a second drain pipe is fixedly connected between the bottom of the fish toilet and the bottom of the fish toilet, and a fish feces collection device is provided at one end of the second drain pipe.

[0009] Preferably, a third drain pipe is fixedly connected to one side of the microfilter, and the other end of the third drain pipe is located in the inner cavity of the fish feces collection device.

[0010] Preferably, one side of the fish feces collection device is fixedly connected to a return water pipe, and the other end of the return water pipe is located between the ozone generator and the biochemical disinfection tank.

[0011] The advantages of this utility model are: This invention utilizes a first drain pipe connected to a fish toilet, and a first water pump creates negative pressure at the connection point, transporting water from the fishpond to a microfiltration unit for backwashing to filter out small particulate pollutants. A second water pump then draws the water from the microfiltration unit to an ozone generator for sterilization. Because high-density aquaculture environments are prone to ammonia and nitrite contamination due to the decomposition of fish feces and feed residue, a nitrifying bacteria are cultivated in the biochemical disinfection tank. This tank degrades ammonia and nitrite in the water. The treated water is then pumped back to a storage tower for recycling, creating a high-quality, oxygen-rich, and temperature-suitable aquaculture environment. This is beneficial for high-value species in high-density aquaculture and solves the problems of traditional high-density aquaculture systems, such as simple layout, limited functionality, inability to promptly remove uneaten feed and feces, leading to ammonia and nitrite accumulation, lack of attachment carriers for beneficial microorganisms like nitrifying bacteria, obstructed nitrogen circulation, and easy water quality deterioration.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0016] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a high-density aquaculture system. (Refer to...) Figures 1 to 5 A high-density aquaculture system includes multiple fish ponds 1. Each fish pond 1 has a fish toilet 2 fixedly installed inside its cavity. The bottoms of the fish toilets 2 are fixedly connected to a first sewage pipe 3. The other end of the first sewage pipe 3 is fixedly connected to a first water pump 4. The output end of the first water pump 4 is equipped with a microfilter 5. The output end of the microfilter 5 is fixedly connected to an ozone generator 6. The output end of the ozone generator 6 is fixedly connected to a biochemical disinfection tank 7. The output end of the biochemical disinfection tank 7 is fixedly connected to a second water pump 8. The output end of the second water pump 8 is fixedly connected to a water storage tower 9. Fish pond 1 is circular with a smooth inner wall, ensuring uniform water exchange. The bottom of fish pond 1 is designed with a sloping cone shape, greater than 30 degrees, to facilitate the collection of fish waste by the fish toilet 2. The size of fish pond 1 should not be too large, as longer retention of fish waste pollutants negatively impacts water quality. Through the first drain pipe 3 of fish toilet 2, a first water pump 4 creates negative pressure at the connection between the first drain pipe 3 and fish toilet 2, transporting water from fish pond 1 to the microfiltration machine 5 for backwashing to filter small particulate pollutants. The water is then further filtered by a second water pump 8. Water from machine 5 is pumped to ozone generator 6 for sterilization and disinfection. Because fish feces and feed residues in high-density aquaculture environments are prone to decomposition, ammonia nitrogen and nitrite levels are easily exceeded. Therefore, nitrifying bacteria are cultivated in biochemical disinfection tank 7. After passing through biochemical disinfection tank 7, ammonia nitrogen and nitrite in the water can be degraded. The treated water is returned to water storage tower 9 through second water pump 8 for recycling, thus creating an aquaculture environment with good water quality, sufficient dissolved oxygen, and suitable temperature, which is conducive to high-density aquaculture of high-value species. The bottom and enclosure of fish pond 1 are made of CMS material. The bottom of fish pond 1 (multiple fan-shaped splices to form a cone) and the enclosure (with copper coin-shaped reinforcing ribs on the surface) are both sheet-like and are assembled and fixed with stainless steel dovetail screws and sealant. The bottom and enclosure can be widened and heightened, and have the advantages of convenient assembly and disassembly and strong corrosion resistance.

[0017] Reference Figures 1 to 3 There are several water storage towers 9, and several water storage towers 9 are fixedly connected by connecting pipes 10. One of the water storage towers 9 is fixedly connected to a water supply pipe 11, and the surface of the water supply pipe 11 is fixedly connected to an aeration and oxygenation pipe 12. There are several aeration and oxygenation pipes 12, and several aeration and oxygenation pipes 12 are respectively set on one side of several fish ponds 1. Through the set aeration and oxygenation pipes 12, two water storage towers 9 are connected by connecting pipes 10. It has significant advantages in water supply, water storage, emergency protection and water resource management. Through the cooperation of water supply pipes 11 and aeration and oxygenation pipes 12, the efficiency of water supply to fish ponds 1 is ensured, while increasing dissolved oxygen in the water. At the same time, the water flow is continuously concentrated in the middle of fish ponds 1, and pollutants such as fish uneaten food and feces are discharged from fish ponds 1 through the fish toilet 2 and the first sewage pipe 3 set in the middle.

[0018] Reference Figure 3 A second drain pipe 13 is fixedly connected to the bottom of the fish toilet 2. A fish feces collection device 14 is installed at one end of the second drain pipe 13. Through the second drain pipe 13, fish feces and impurities with larger particles in the water are discharged into the fish feces collection device 14 for centralized filtration, thereby improving the water filtration efficiency.

[0019] Reference Figure 5 A third drain pipe 15 is fixedly connected to one side of the microfilter 5. The other end of the third drain pipe 15 is located in the inner cavity of the fish feces collection device 14. Through the third drain pipe 15, small particulate pollutants filtered by the backwashing of the microfilter 5 can be discharged to the fish feces collection device 14 for centralized collection.

[0020] Reference Figure 5 A return water pipe 16 is fixedly connected to one side of the fish feces collection device 14. The other end of the return water pipe 16 is located between the ozone generator 6 and the biochemical disinfection tank 7. Through the return water pipe 16, the water in the fish feces collection device 14 can be transported to the pipe between the ozone generator 6 and the biochemical disinfection tank 7 so that it can enter the biochemical disinfection tank 7 for sterilization and disinfection.

[0021] Working Principle: Several fish ponds 1 are placed in an indoor greenhouse to maintain a stable water temperature. Fish ponds 1 are circular with smooth inner walls, ensuring uniform water exchange. The bottom of fish pond 1 is designed with a sloping cone shape, with a slope greater than 30 degrees, facilitating the collection of fish waste by the fish toilets 2. The size of fish pond 1 should not be too large, as longer retention of fish waste pollutants negatively impacts water quality. Through the first drain pipe 3 of the fish toilets 2, a first water pump 4 creates negative pressure at the connection between the first drain pipe 3 and the fish toilets 2, transporting water from fish pond 1 to a microfiltration unit 5 for backwashing, filtering out small particulate pollutants. A second water pump 8 then draws the water from the microfiltration unit 5 to an ozone generator 6 for sterilization and disinfection. Because fish waste and feed residue decompose easily in high-density aquaculture environments, ammonia nitrogen and... The nitrite content in the water was too high, so nitrifying bacteria were cultivated in the biochemical disinfection tank 7. The biochemical disinfection tank 7 can degrade the ammonia nitrogen and nitrite in the water. The treated water is returned to the water storage tower 9 through the second water pump 8 for recycling. The two water storage towers 9 are connected by the connecting pipe 10, which has significant advantages in water supply, water storage, emergency protection and water resource management. The water supply pipe 11 and the aeration and oxygenation pipe 12 work together to ensure the efficiency of water supply to the fish pond 1, while increasing the dissolved oxygen in the water. At the same time, the water flow continuously concentrates in the middle of the fish pond 1, and pollutants such as fish uneaten food and feces are discharged into the fish toilet 2 and the first sewage pipe 3 in the middle of the fish pond 1. This creates a breeding environment with good water quality, sufficient dissolved oxygen and suitable temperature, which is conducive to the high-density breeding of high-value species.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
