Description

Technical Field

[0001] The utility model relates to the relevant field of anaerobic reactors, in particular to an anaerobic reactor. Background Art

[0002] The anaerobic fluidized bed reactor is a highly efficient biofilm treatment method. It utilizes materials with large surface areas, such as sand, as carriers. Anaerobic microorganisms form membranes on the surface of the sand or other carriers, flowing through the sewage. The microorganisms come into contact with the organic matter in the sewage, adsorbing and decomposing the organic matter, thereby achieving the purpose of treatment. The anaerobic reactor was the first in anaerobic treatment both domestically and internationally to use sand as a carrier. The equipment structure consists of two inner and outer cylinders. A special axial flow pump is used to circulate the sewage and the organic biofilm sand in the outer cylinder to achieve the purpose of fluidization.
