Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a biological purification chamber for aquaculture. Background Technology

[0002] Aquaculture includes extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves stocking seedlings in small to medium-sized natural water bodies and raising aquatic products entirely based on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming involves raising aquatic products in smaller bodies of water using feeding and fertilization methods, such as pond fish farming, net cage fish farming, and enclosure aquaculture. High-density intensive farming uses methods such as flowing water, temperature control, aeration, and feeding high-quality feed to achieve high yields through high-density farming in small bodies of water, such as high-density flowing water fish and shrimp farming.

[0003] As aquaculture develops towards intensification and industrialization, high-density aquaculture models (such as factory-style recirculating aquaculture and land-based container aquaculture) place higher demands on water quality control.

[0004] Chinese utility model patent CN216219598U discloses an eco-friendly biological purification system for recirculating aquaculture. This system treats wastewater biologically, has low energy consumption, and provides thorough treatment. It can also reduce aquaculture costs, improve the quality of aquatic products, and greatly increase aquaculture efficiency.

[0005] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: after the purified water is injected into the aquaculture pond, the device cannot clean up the feces produced by the organisms in the aquaculture pond while simultaneously purifying the water. The accumulation of feces can easily lead to the growth of bacteria, thereby affecting the health of aquatic organisms. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a biological purification chamber for aquaculture includes a first biological pool 1 and a second biological pool 2. The second biological pool 2 is located at one end of the first biological pool 1. A third biological pool 3 is provided on one side of the second biological pool 2. A clear water pool 4 is provided at one end of the third biological pool 3. An ultraviolet disinfection device 5 is provided at one end of the clear water pool 4. A control cabinet 7 is provided at one end of the ultraviolet disinfection device 5. A circulating water pump 6 is provided at one end of the first biological pool 1. A servo motor 11 is provided at one end of the top of the first biological pool 1. A rotating shaft 12 is fixedly connected to one end of the servo motor 11. A drive wheel 13 is fixedly connected to one end of the rotating shaft 12. A drive belt 14 is connected to the outside of the drive wheel 13. A rotating drum 15 is connected to the inside of the drive belt 14. The rotating drum 15 is rotatably connected inside the first biological pool 1. Multiple filter discs 16 are provided on the outside of the rotating drum 15. In this process, by starting the servo motor 11, the servo motor 11 will drive the rotating shaft 12 to rotate, the rotating shaft 12 will drive the drive wheel 13 to rotate, the drive wheel 13 will drive the transmission belt 14 to move, the transmission belt 14 will drive the rotating drum 15 to rotate, and the rotating drum 15 will drive the filter disc 16 to rotate. The filter disc 16 is covered with filter media such as filter screen or filter cloth on its surface, which is used to intercept suspended particles and impurities in the water, thereby playing the role of filtering and purifying the water quality. The sewage enters the interior of the rotating drum 15 after being filtered by the filter disc 16, and finally is discharged from the outlet pipe 9 to the next biological tank for purification. Secondly, the main function of the clear water tank 4 is to store the clear water after it has been purified by the biological tank. It plays a role in buffering and regulating the water volume, providing a stable water source that meets the water quality requirements for subsequent aquaculture. At the same time, it can also settle the small particulate matter that may remain in the water after the biological tank is purified to a certain extent. The ultraviolet disinfection equipment 5 utilizes the sterilization principle of ultraviolet light to further disinfect the water after it has been purified by the biological pond. It can effectively kill pathogens, viruses, parasites and other harmful microorganisms in the water, reduce the risk of disease transmission during aquaculture, and ensure the healthy growth of farmed organisms. Furthermore, an inlet pipe 8 is provided at one end of the first biological pool 1, and an outlet pipe 9 is provided at the other end of the first biological pool 1. The circulating water pump 6 draws the aquaculture water from the aquaculture area and transports it to the inside of the first biological pool 1 through the inlet pipe 8 for purification treatment. The purified water is then transported to the inside of the second biological pool 2 through the outlet pipe 9, and then passes through the third biological pool 3, the clear water pool 4 and the ultraviolet disinfection equipment 5 in sequence, or is sent back to the aquaculture area to ensure that the water continuously circulates in the system, so that the purification process can be carried out continuously. Furthermore, a sludge discharge pipe 10 is installed at the bottom of the first biological tank 1. The sludge discharge pipe 10 is used to discharge the sludge that has settled in the sewage. When opened, it prevents these impurities from entering the treated water again, thereby ensuring the cleanliness of the drainage. Furthermore, a fixed plate 17 is fixedly connected to one inner wall of the first biological pool 1. One end of the rotating cylinder 15 is rotatably connected to the inside of the fixed plate 17. A limiting ring 18 is fixedly connected to one end of the rotating cylinder 15. A limiting groove 19 is machined inside the fixed plate 17. The limiting ring 18 is rotatably connected to the inside of the limiting groove 19. When the rotating cylinder 15 rotates, the rotating cylinder 15 will drive the limiting ring 18 to rotate. The limiting ring 18 will rotate along the inside of the limiting groove 19. The limiting groove 19 will limit the movement of the limiting ring 18. Furthermore, the second biological pool 2 and the third biological pool 3 are filled with packing material suitable for the attachment and growth of microorganisms. When water flows through the interior of the second biological pool 2 and the third biological pool 3, pollutants such as ammonia nitrogen and nitrite come into full contact with microorganisms and undergo biodegradation under the action of microorganisms. As a result, after treatment by the second biological pool 2 and the third biological pool 3, the concentration of harmful substances such as ammonia nitrogen and nitrite in the water is greatly reduced.

[0018] Working principle: By starting the circulating water pump 6, water containing pollutants such as metabolic products of aquaculture organisms and uneaten feed in the aquaculture area is pumped out and transported to the first biological tank 1 through the inlet pipe 8 for purification. The wastewater is filtered by the filter disc 16 and enters the rotating drum 15. Finally, it is discharged from the outlet pipe 9 to the next biological tank for purification. Then, it passes through the second biological tank 2 and the third biological tank 3 in sequence. Pollutants such as ammonia nitrogen and nitrite come into full contact with microorganisms and undergo biodegradation under the action of microorganisms, thereby significantly reducing the concentration of harmful substances such as ammonia nitrogen and nitrite in the water. The purified water flowing out of the third biological tank 3 enters the clear water tank 4. Under the irradiation of ultraviolet light, the harmful microorganisms in the water are inactivated, further improving the safety of the water quality. Finally, the disinfected water is transported back to the aquaculture area, completing a complete cycle of purification.

[0019] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
