[0002] Nitrification refers to the reaction of introducing nitro groups into organic compound molecules. Denitrification, also known as denitrification, refers to the biochemical process in which bacteria reduce nitrogen in nitrates to nitrogen gas through a series of intermediates. Nitrification and denitrification are used to remove nitrogen from organic wastewater and high-nitrate wastewater to reduce nitrogen pollution and eutrophication problems discharged into rivers.

[0003] However, the current nitrification and denitrification reactors still have some shortcomings. The existing nitrification and denitrification reactors have not yet fully considered the stirring structure. During the use of the nitrification and denitrification reactor for sewage treatment, if the nitrification and denitrification reactor does not fully consider the stirring structure, the contact between substances may be limited, making the nitrification and denitrification reaction not thorough enough, affecting the reaction efficiency, and making it inconvenient for staff to use the nitrification and denitrification reactor.
