Anaerobic ammonium oxidation reactor and wastewater treatment method and treatment system
ActiveCN118993337BOpen efficientlyObvious advantages in energy saving and environmental protectionWater aerationTreatment with anaerobic digestion processes
The present invention relates to the field of sewage treatment, and specifically to an anaerobic ammonium oxidation reactor and a wastewater treatment method and treatment system. The anaerobic ammonium oxidation reactor includes a reaction tube and a plurality of aeration units. The aeration unit uses a support frame to lift the diaphragm during aeration, and the elevation of the support frame is controlled by one-way inflation into the high-pressure air pipe. Under the action of the one-way valve, the high-pressure air pipe is inflated once and used throughout the whole process. There is no need to continuously provide the energy required to lift the diaphragm during aeration, thereby reducing energy consumption, saving energy and protecting the environment. At the same time, the support frame is an umbrella-shaped structure, which can evenly support the diaphragm, ensure that the aeration micropores are effectively opened, and improve the aeration effect and aeration efficiency; further, when the support frame is reset, the gas in the high-pressure air pipe is ejected toward the diaphragm through the support frame, and the support frame rotates to knock the rubber column. The ejected gas and the vibration of the rubber column jointly cause the diaphragm to vibrate, thereby avoiding being stuck by particulate matter before it is closed, and improving the service life of the diaphragm.
