Description

Technical Field

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

[0002] In the current environment of ever-increasing environmental protection demands, the effective treatment of high-ammonia nitrogen wastewater has become a key issue for many industries. Fermentation treatment is a commonly used and effective method for treating high-ammonia nitrogen wastewater, and the performance of the equipment directly affects the treatment effect.

[0003] In existing technologies, fermentation equipment for treating high-ammonia-nitrogen wastewater mostly employs relatively traditional mechanical structures. Inside the fermenter, a simple stirring device is typically installed, with a motor driving the stirring blades to mix the wastewater with the microbial community. The ammonia-nitrogen is then degraded through the metabolism of the microorganisms. Wastewater input and output are primarily handled by connecting different treatment units via pipelines, with pumps providing power to circulate the wastewater within the system.

[0004] However, existing fermentation equipment for treating high-ammonia nitrogen wastewater inevitably accumulates biofilm, inorganic salt scale, and sludge on the inner walls of the fermenter, pipes, and agitators after prolonged use. The presence of these deposits significantly impacts the mass transfer efficiency within the equipment. Due to this obstructed mass transfer process, microorganisms cannot fully contact the ammonia nitrogen in the wastewater, leading to a gradual decrease in their activity and a substantial reduction in ammonia nitrogen degradation efficiency. This severely affects the equipment's treatment effect on high-ammonia nitrogen wastewater and its overall operational stability. Therefore, this paper proposes a fermentation equipment for treating high-ammonia nitrogen wastewater to address these problems. Utility Model Content

This improves the practicality of the equipment for fermentation treatment of high ammonia nitrogen wastewater. Attached Figure Description

[0037] Working principle: When using the equipment for fermenting and treating high ammonia nitrogen wastewater, firstly, the water source is connected to the input end of the nozzle 11. Then, the water is evenly sprayed into the inside of the fermentation tank 5 through the nozzle 11. Then, the output end of the reduction motor 9 drives the first transmission shaft 10 to rotate. When the first transmission shaft 10 rotates, it will drive the hollow column 13 on the outer wall to rotate. Next, when the hollow column 13 rotates, it will drive the first scraper 16 inside to rotate on the inner wall of the fermentation tank 5. Then, when the first scraper 16 is under force, it will drive the sliding column 15 on the side wall to slide inside the hollow column 13. Next, when the first scraper 16 is under force, it will drive the sliding column 15 on the side wall to rotate. Then, when the sliding column 15 is under force, it will drive the first spring 14 on the side wall to rotate as well. In summary, the first scraper 16 scrapes away the impurities inside the fermentation tank 5, and then the nozzle 11 cleans the inside, achieving the effect of cleaning the inside of the fermentation tank 5.

[0038] Next, when adding the additive in a quantitative manner, the additive is first placed inside the material column 19 via 29. Then, the output end of the servo motor 18 drives the second transmission shaft 20 to rotate. The rotation of the second transmission shaft 20 will drive the rotating scraper 21 on the outer wall to rotate as well. The rotating scraper 21 will then rotate inside the material column 19. Next, the rotation of the second transmission shaft 20 will drive the threaded rod 22 on the outer wall to rotate inside the material column 19 as well. Then, the output end of the electric push rod 24 will drive the second connecting block 28 to rotate. During the rotation of the second connecting block 28, the rotating door 25 on the side wall will rotate. The rotating door 25 rotates at one end of the material column 19. Then, during the force applied to the rotating door 25, the second connecting block 28 at the top will rotate as well. The rotation of the second connecting block 28 will then rotate on the outer wall of the limiting shaft 26, and the limiting shaft 26 will provide a limiting rotation for the rotating door 25, thus achieving the effect of quantitatively dispensing the additive.
