Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and more specifically, to a nitrification reactor. Background Art

[0002] Nitration refers to the reaction of introducing nitro groups into organic compound molecules. Nitro groups can be connected to carbon atoms in organic compounds to form nitro compounds, to oxygen atoms to form nitroester compounds, or to nitrogen atoms to form nitramines.

[0003] In the process of short-range nitrification-denitrification, the SBR reactor needs to go through the stages of pre-aeration-water inlet-aeration-sedimentation-sludge discharge-water outlet-idleness. Since the reactor does not need to be aerated all the time, the existing reactor will adhere to the inner bottom wall of the reactor during the sedimentation process, requiring technicians to clean it from time to time. The difficulty in cleaning will bring inconvenience to the use of the device. At the same time, frequent cleaning will also have a certain impact on the stability of the system.
