[0002] In recent years, with the improvement of people's living standards, the demand for aquatic products has been increasing, which has also driven the rapid development of my country's aquaculture industry. The diversification of aquaculture species, the variety of aquaculture methods, and the refinement of aquaculture processes have led to continuous improvements in aquaculture technology and yield. The emergence of this patented technology will provide experimental conditions for the biology, aquatic environment, ecology, and physiology of aquaculture species, and will also provide theoretical and practical basis for the development of aquaculture technology and processes.

[0003] Currently, recirculating aquaculture systems used in laboratory settings typically employ multiple fixed series structures to house laboratory animals. Animal excrement and leftover feed particles are usually filtered out using filter cotton or filter balls, or fluidized bed filters with physical and chemical filtration chambers to remove particulate matter from animal waste. However, there is no systematic water treatment equipment or method to digest and decompose protein breakdown products and nitrogenous compounds that accumulate in the water. This leads to the deterioration and turbidity of the aquaculture water, affecting the experimental animal rearing process and consequently impacting the accuracy and completeness of the data.

[0023] Please see Figure 1-4 This utility model provides a technical solution: an aquaculture experimental system, including an experimental platform 1, multiple water tank supports 2, experimental water tanks 3, a return water pipe 4, a microfilter 5, a water pump 6, a low-level water tank 7, a heat exchanger 8, a water guide pipe 9, an ultraviolet tube 10, a high-level biological package water tank 11, a water supply pipe 12, a second water pump 21, and a second water guide pipe 22. Multiple water tank supports 2 are fixedly mounted on the experimental platform 1 and arranged sequentially from left to right. Each water tank support 2 has one experimental water tank 3. The return water pipe 4 is sequentially connected to the outlet of each experimental water tank 3 and finally fixedly connected to the inlet of the microfilter 5. The outlet of the microfilter 5 is connected to the low-level water tank 7 via the first water pump 6; the microfilter 5 itself has a drain pipe for drainage; the outlet of the low-level water tank 7 is connected to the inlet of the heat exchanger 8 via the second water pump 21; the outlet of the heat exchanger 8 is connected to the inlet of the ultraviolet tube 10 via the first water guide pipe 9; the high-level biological bag water tank 11 contains biological filter media; the outlet of the ultraviolet tube 10 is connected to the inlet of the high-level biological bag water tank 11 via the second water guide pipe 22; the outlet of the high-level biological bag water tank 11 is connected to the inlet of each experimental water tank 3 via a water supply pipe 12, thereby forming a closed water circulation loop.

[0024] The water in the aquaculture tank is first collected through the return pipe 4 and then enters the microfilter 5 for preliminary physical filtration to remove suspended particles and other impurities. Subsequently, the first water pump 6 transports the filtered water to the low-level water tank 7, providing a buffer and storage for subsequent water treatment. The water in the low-level water tank 7 is then pumped to the heat exchanger 8 by the second water pump 21, achieving precise temperature control and ensuring the cultured organisms are in a suitable temperature environment. Next, the water flows into the ultraviolet tube 10 for disinfection and sterilization, effectively removing pathogenic microorganisms and ensuring the hygiene and safety of the aquaculture water. Next, the water enters the high-level bio-pack tank 11, where it undergoes biological purification using the biological filter media within the bio-pack. The high-level bio-pack tank 11 improves the ammonia nitrogen structure of the water, converting harmful ammonia nitrogen into harmless nitrate nitrogen, while simultaneously providing sufficient dissolved oxygen to further degrade organic matter and ammonia nitrogen, thus improving water quality. Finally, the water, after undergoing multi-stage treatment, is redistributed to each experimental water tank 3 through the water supply pipe 12, completing a full water circulation process and ensuring the continuous stability and cleanliness of the water quality.

[0025] Specifically, the return water pipe 4 is installed along multiple water tank supports 2, and each return water pipe 4 has a first branch pipe 13 at the outlet of each experimental water tank 3. Each first branch pipe 13 is connected to the outlet of the corresponding experimental water tank 3. At the outlet of each experimental water tank 3, the return water pipe 4 has a first branch pipe 13. These first branch pipes 13 serve as dedicated channels connecting the return water pipe 4 and the outlet of the experimental water tank 3, realizing direct connection between the outlet of each experimental water tank 3 and the return water pipe 4. Each first branch pipe 13 is precisely connected to the outlet of the corresponding experimental water tank 3, ensuring that the water in the aquaculture tank can be smoothly discharged and enter the return water pipe 4, thereby effectively collecting the effluent from each experimental water tank 3 and providing a stable water source input for subsequent water treatment processes.

[0026] Specifically, the outlet of the elevated bio-pack water tank 11 is connected to a water supply pipe 12. The water supply pipe 12 extends along multiple water tank supports 2, and a second branch pipe 14 is installed at the inlet of each experimental water tank 3. Each second branch pipe 14 is equipped with a control valve 15. These second branch pipes 14 serve as dedicated channels connecting the water supply pipe 12 to the inlet of the experimental water tank 3, realizing the distribution of water from the elevated bio-pack water tank 11 to each experimental water tank 3. Each second branch pipe 14 is equipped with a control valve 15, which can be independently adjusted to control the amount of water entering each experimental water tank 3, ensuring the controllability and stability of the water flow.

[0027] Specifically, the aquaculture experimental system also includes a flushing pump 16. The inlet of the flushing pump 16 is connected to the low-level water tank 7, and the outlet of the flushing pump 16 is connected to the microfilter 5 via a flushing pipe 17. The connection between the inlet of the flushing pump 16 and the low-level water tank 7 ensures that the flushing pump 16 has a sufficient source of clean water. When it is necessary to clean the microfilter 5, the flushing pump 16 pumps water from the low-level water tank 7 to the flushing pipe 17. The other end of the flushing pipe 17 is connected to the microfilter 5. Through the flushing pipe 17, the flushing pump 16 delivers water to the inside of the microfilter 5 to flush the filter screen or filter media, remove the dirt and impurities accumulated on the filter screen, maintain the filtration efficiency of the microfilter 5, and extend its service life.

[0028] Specifically, a protein generator 18 is connected to the low-level water tank 7. The inlet pipe and outlet pipe of the protein generator 18 are connected to the low-level water tank 7. A submersible pump is installed inside the low-level water tank 7. The outlet of the submersible pump is connected to the inlet pipe of the protein generator 18, providing water flow power to the protein generator 18, thereby achieving water treatment. The submersible pump draws water from the low-level water tank 7 and delivers it to the protein generator 18. In the protein generator 18, organic matter such as proteins in the water is removed through a mechanism (e.g., foam separation). The connection method of the submersible pump is existing technology. The treated water returns to the low-level water tank 7 through the outlet pipe. The protein generator 18 uses the principle of air flotation separation, utilizing the surface tension of air bubbles to adsorb and remove suspended solids, proteins, uneaten feed, feces, and other organic impurities from the aquaculture water. The outlet of the protein generator 18, connected to the low-level water tank 7, allows the treated water to flow back to the low-level water tank 7, forming a closed water circulation loop. This connection method ensures that the water treated by the protein generator 18 can re-enter the water circulation system, improving the utilization rate of water resources while also ensuring the cleanliness and stability of water quality.

[0029] Specifically, the elevated biological tank 11 is equipped with an overflow pipe 19, the outlet of which is connected to the lower tank 7. When the water level in the elevated biological tank 11 exceeds a certain height, excess water flows out through the overflow pipe 19, and the outlet of this overflow pipe 19 is directly connected to the lower tank 7, allowing the overflowing water to flow smoothly into the lower tank 7. This design ensures that the elevated biological tank 11 will not overflow due to fullness, while also effectively utilizing water resources by guiding the overflowing water to the lower tank 7 for reuse or further treatment. Through this connection method, water flow control and resource optimization between the two tanks are achieved.

[0030] Specifically, the aquaculture experimental system also includes a water quality monitoring and control system 20. The water quality monitoring and control system 20 includes a PLC control cabinet and temperature sensors, turbidity sensors, pH sensors, and ammonia nitrogen sensors installed in the experimental water tank 3. The signal output terminals of each sensor are connected to the signal input terminals of the water quality monitoring and control system 20 one by one through signal transmission lines. The water quality monitoring and control system 20 is connected to the control input terminals of the microfilter 5, the first water pump 6, the second water pump 6, the heat exchanger 8, the ultraviolet tube 10, the protein generator 18, and the flushing pump 16 through control signal output lines.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
