Description

Technical Field

[0001] This utility model is a multi-stage high-efficiency aquaculture wastewater treatment device, belonging to the field of wastewater treatment. Background Technology

[0002] Marine aquaculture wastewater refers to the wastewater generated during the marine aquaculture process, which contains waste, excrement of farmed animals, and feed residue. This wastewater contains various pollutants from feed, aquatic product feces, bottom sediment, and gravel, mainly nitrogen and phosphorus. To treat this wastewater, it is necessary to provide aquaculture wastewater treatment equipment.

[0003] In existing technologies, filter plates are used to filter solid particles such as sediment in aquaculture wastewater. Then, an ozone generator is used to disinfect and sterilize bacteria and viruses in the wastewater. By setting up a sand planting layer inside the treatment tank, the nitrogen and phosphorus in the filtered wastewater can be effectively filtered, preventing pollution of the aquatic environment after the wastewater is discharged. However, the treatment technology still has problems because a large amount of impurities will accumulate on the top of the filter plates after long-term use, requiring regular cleaning. The filter plates are fixed by bolts, and the disassembly and assembly require the use of tools, which is a limitation and inconvenient for cleaning or replacing the filter screen, resulting in low performance. Therefore, this application proposes a multi-stage high-efficiency aquaculture wastewater treatment device that is easy to clean. Utility Model Content

[0026] Please see Figure 1-5 This utility model provides a technical solution: a multi-stage high-efficiency aquaculture wastewater treatment device, including a filter box 1, a sterilization component, and an oxygenation box 3. The filter box 1 is equipped with a filter element, which includes an upper frame 4 and a lower frame 5. The filter box 1 and the sterilization component are connected by a pipe 6. Filter screens 7 are provided on the inner sides of both the upper frame 4 and the lower frame 5. A cleaning component is provided on the filter box 1. The cleaning component includes an L-shaped plate 8 fixed to the outer wall of the filter box 1. An electric telescopic rod 9 is provided on the L-shaped plate 8.

A cleaning component 14 is fixed at the other end of the auxiliary fixing rods 13. A docking pipe 35 is provided between the sterilization component and the oxygenation box 3.

[0027] See Figure 1The bottom of the movable plate 10 is provided with two movable wheels 15 that slide on the L-shaped plate 8. The outside of the filter box 1 is provided with a pump 16, and the pump 16 is provided with an output pipe. The output pipe is provided with a plurality of separation pipes 17 located inside the filter box 1. The bottom of the separation pipes 17 is evenly provided with tailwater spray pipes. The movable wheels 15 at the bottom of the movable plate 10 provide a certain support for the design components of the cleaning assembly. The separation pipes 17 separate the tailwater to be treated and discharge it onto the filter screen 7 to improve the filtration effect.

[0028] See Figure 3 The cleaning component 14 includes a scraper 18 and a cleaning plate 19 with bristles. A mounting plate 20 is fixedly provided at the top of the cleaning plate 19. The mounting plate 20 is fixedly connected to the top of the scraper 18 with screws. The scraper 18 scrapes away impurities, and the cleaning plate 19, with the help of bristles, further cleans the impurities.

[0029] See Figure 1 and Figures 3-5 The filter box 1 has a through-hole groove 21 on its side wall for the cleaning component 14 to pass through. The blocking plate 12 corresponds to the through-hole groove 21. A ring-shaped sealing gasket 22 is provided on the outer surface of the blocking plate 12. A ring-shaped sealing gasket 23 is provided on one side of the sealing plate 11. There are two through-hole grooves 21. Two flow guide plates 24 are fixedly provided on the outer wall of the filter box 1. A secondary sealing plate 25 is fixedly provided on one side of the upper frame 4 and the lower frame 5. The outer side of the filter box 1 is provided with There is a receiving box 26, and a side plate 27 is fixed on the outer wall of the receiving box 26. The side plate 27 is fixed to the outer wall of the filter box 1 with screws. The blocking plate 12 corresponds to the through groove 21 and seals the inner wall of the through groove 21 with the sealing gasket 1 22. The size of the sealing plate 11 is larger than the size of the through groove 21. The sealing plate 11 covers the through groove 21. The sealing gasket 23 fits tightly with the outer wall of the filter box 1, which plays a double sealing role for the through groove 21. Impurities can be discharged along the guide plate 24.

[0030] See Figure 1 , Figure 6 and Figure 7The sterilization component comprises multiple interconnected cylindrical tubes 2. Each cylindrical tube 2 has multiple support rods that fix glass tubes 28 inside. A photocatalytic mesh 29 is fixedly connected to the inner wall of each glass tube 28. Multiple ultraviolet lamps 31 are installed inside each cylindrical tube 2. Baffles 32 are evenly distributed inside each cylindrical tube 2. An oxygenation tank 3 is equipped with a dissolved oxygen sensor 33. A drive motor is fixedly mounted on the outer wall of the oxygenation tank 3. A stirrer 34 located inside the oxygenation tank 3 is located at the output end of the drive motor. The oxygenation tank 3 also has a final outlet pipe 36, connected to a control valve. An oxygenator is located on one side of the outer wall of the oxygenation tank 3, with its oxygen pipe located inside the oxygenation tank 3. When the ultraviolet lamps are turned on, they emit light and irradiate the photocatalytic mesh 29 through the glass tubes 28, causing the photocatalytic mesh to catalyze water molecules into highly oxidizing hydroxyl radicals. Free radicals efficiently disinfect and inactivate bacteria in the effluent, achieving sterilization of the filtered effluent through photocatalysis. Since both the photocatalytic mesh and ultraviolet lamps are reusable, and no chemicals are used in the sterilization process, the economic efficiency and environmental friendliness of the effluent treatment process are improved. Furthermore, each cylinder 2 is equipped with baffles 32 to reduce flow rate and extend sterilization time. After storing a certain amount of effluent in the oxygenation tank 3, effluent treatment is stopped, and then the agitator 34 is activated to oxygenate the effluent inside the oxygenation tank 3. The oxygen generated by the aerator enters the effluent through the delivery pipe, increasing the oxygen content. When the oxygen content of the effluent reaches the preset threshold of the dissolved oxygen sensor, the aerator stops working, and the control valve (a solenoid valve) opens the final outlet pipe 36. The agitator 34 further accelerates the oxygenation efficiency.

[0031] In actual operation, the filter screens 7 inside the upper frame 4 and lower frame 5 perform layer-by-layer filtration. The electric telescopic rod 9 is periodically activated to move the moving plate 10, sealing plate 11, blocking plate 12, auxiliary fixing rod 13 and cleaning component 14. Finally, the cleaning component 14 cleans the filter screen 7 to prevent clogging during subsequent use of the device, which would lead to poor wastewater treatment. During cleaning, the sealing plate 11 and blocking plate 12 no longer block the through groove 21, so the cleaned impurities can be pushed out along the through groove 21 and collected. Then, the filtered wastewater is sterilized using the photocatalytic principle, followed by oxygenation, and finally discharged for reuse.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
