Description

Technical Field

[0001] This utility model relates to the field of ammonia nitrogen wastewater treatment technology, and in particular to an ammonia nitrogen nitrification reaction device for wastewater treatment. Background Technology

[0002] Ammonia nitrification is a crucial step in wastewater treatment. Wastewater treatment ammonia nitrification reactors primarily utilize microorganisms to convert ammonia nitrogen. This process effectively reduces the concentration of this harmful component in wastewater, mitigating its toxicity to aquatic organisms. Simultaneously, it creates conditions for further denitrification of wastewater, improving overall wastewater treatment quality.

[0003] The basic structure of an ammonia nitrogen nitrification reactor for wastewater treatment includes an aeration system, a reaction tank, and a sedimentation zone. The aeration system oxygenates the wastewater, as nitrification is an aerobic process. The reaction tank is the main site of nitrification, where microorganisms convert ammonia nitrogen. The sedimentation zone separates sludge from the treated water, allowing the treated water to be discharged while some of the sludge is recycled to maintain a sufficient microbial population.

[0004] In existing technologies, some ammonia nitrogen nitrification reactors require the addition of nitrifying bacteria during wastewater purification. Insufficient addition results in low nitrifying bacteria concentration within the reactor, leading to a slow conversion of ammonia nitrogen to nitrate and excessive ammonia nitrogen levels in the effluent. Excessive addition increases costs, causes bacteria to compete for resources, and the resulting metabolic waste may adversely affect water quality and the reactor's ecosystem. Therefore, this wastewater treatment ammonia nitrogen nitrification reactor is proposed to address these issues. Utility Model Content

The bottom end of the fixed plate 20 is fixedly connected to a limiting plate 22, which provides support. The bottom of the moving plate 18 is fixedly connected to a storage tank 23, which can hold nitrifying bacteria agent. The bottom of the storage tank 23 is rotatably connected to a lid 24. When the lid 24 is suspended, the nitrifying bacteria agent inside can push the lid 24 open to achieve a quantitative feeding effect.

[0035] The bottom of the lid 24 is slidably connected to the top of the limiting plate 22. The limiting plate 22 can prevent the material inside the lid 24 from falling out. The top of the processing tank 13 is fixedly connected to the funnel 25, which is used to hold nitrifying bacteria agent. The bottom of the funnel 25 is in contact with the top of the moving plate 18. The moving plate 18 can prevent the material inside the funnel 25 from falling out during the movement. The top of the discharge port 19 is in contact with the bottom of the funnel 25, and the material inside the funnel 25 can be transferred through the discharge port 19.

[0036] Refer to Figure 2 and Figure 4A drive assembly is fixedly connected to the top of the treatment tank 13. The drive assembly includes a second motor 14, which serves as a drive pad. The external part of the second motor 14 is fixedly connected to the top of the treatment tank 13. A rotating rod 15 is fixedly connected to the drive end of the second motor 14, which drives the rotating rod 15 to rotate. Multiple stirring rods 16 are fixedly connected to the external part of the rotating rod 15, which drives the stirring rods 16 to mix and stir during rotation. A solenoid valve pipe 7 is fixedly connected to the left side of the treatment tank 13, which controls the flow of water. The other end of the solenoid valve pipe 7 is fixedly connected to the right side of the filter box 1, through which water can be transmitted to the solenoid valve pipe 7. The left side of the filter box 1 is fixedly connected to the water inlet 2, which can transmit sewage into the interior of the filter box 1. The cleaning components include a lower baffle 3, the bottom of which is fixedly connected to the bottom of the interior of the filter box 1. The top of the interior of the filter box 1 is fixedly connected to an upper baffle 4. The lower baffle 3 and the upper baffle 4 can block most large particles. The interior of the filter box 1 is fixedly connected to a microporous aerator 5, which can enhance the activity of microorganisms.

[0037] Reference Figure 2 and Figure 1 A cleaning component is fixedly connected to the left side of the treatment tank 13, and a motor 8 is fixedly connected to the right side of the filter box 1. The motor 8 serves as a power source, and a rotating shaft 9 is fixedly connected to the drive end of the motor 8. Multiple blades 10 are fixedly connected to the outside of the rotating shaft 9. The motor 8 can drive the rotating shaft 9 to rotate, thereby causing the rotating shaft 9 to drive the blades 10 to rotate. A connecting rod 11 is fixedly connected to the left side of the rotating shaft 9. The rotating shaft 9 can drive the connecting rod 11 to rotate. Two scraper plates 12 are fixedly connected to the outside of the connecting rod 11. When the connecting rod 11 rotates, it can drive the scraper plates 12 to rotate. A filter plate 6 is fixedly connected inside the filter box 1. The filter plate 6 can filter out fine impurities in the water. The near ends of the two scraper plates 12 are respectively attached to the left and right ends of the filter plate 6. The rotating scraper plates 12 can remove the dust on the filter plate 6.

[0038] Working principle: Wastewater is introduced into the filter box 1 through inlet 2. After entering the filter box 1, large debris is blocked by the lower baffle 3, and some debris is also blocked by the upper baffle 4. When the water flows over the surface of the filter plate 6, it can adsorb the tiny debris in the wastewater. At this time, by opening the microporous aerator 5, the survival rate of microorganisms in the wastewater can be improved. After long-term use, the filter plate 6 needs to be cleaned. The motor 8 is started to drive the rotating shaft 9 to rotate. When the rotating shaft 9 rotates, it drives the blades 10 to rotate, thereby achieving the effect of counter-current water flow, which can wash down the microorganisms on the filter plate 6. When the rotating shaft 9 rotates, it drives the connecting rod 11 to rotate, and the connecting rod 11 drives the two scraper plates 12 to rotate, thereby cleaning both sides of the filter plate 6. This method can improve the service life of the filter plate 6 and improve the cleaning effect.

[0039] After filtration, the water is transferred to the treatment tank 13. The moving plate 18 is moved by activating the cylinder 17. When the moving plate 18 moves, it slides in the groove 21 opened in the fixed plate 20 to ensure the stability of the moving plate 18 during movement. When the moving plate 18 moves, it can drive the storage tank 23 fixed at the bottom to move. The nitrifying bacteria agent inside the funnel 25 can enter the storage tank 23 through the discharge port 19. When the storage tank 23 moves, it can drive the lid 24 to move. When the storage tank 23 is suspended, the nitrifying bacteria agent inside the storage tank 23 can push open the lid 24 to achieve the effect of quantitative feeding. At this time, the moving plate 18 can block the bottom of the funnel 25 to prevent the material inside the funnel 25 from leaking out. By quantitatively feeding the nitrifying bacteria agent, it can be ensured that the useless substances in the sewage can be converted into water that is harmless to the water body.
