[0002] Anaerobic biological treatment technology is a highly efficient wastewater treatment method in which organic matter in wastewater is decomposed, metabolized, and digested by anaerobic bacteria under anaerobic conditions, significantly reducing the organic matter content and simultaneously producing biogas. Utilizing the metabolic properties of anaerobic microorganisms, the reduced organic matter in the wastewater acts as a hydrogen acceptor, without the need for external energy, while simultaneously producing energy-rich methane gas. The biogas (containing gaseous substances such as CH4, CO2, N2, H2, O2, and H2S) produced during the degradation of organic matter can be actively utilized to generate economic value.

[0003] During the sewage treatment process, it is necessary to mix the sewage with the treatment liquid. However, the existing anaerobic ammonium oxidation reaction device cannot effectively mix the sewage and the treatment liquid. Due to their different densities, uneven mixing is likely to occur.
