Description

technical field [0001] The invention relates to a sewage biological treatment technology, in particular to an integrated anaerobic ammonium oxidation membrane bioelectrochemical system for denitrification and carbon removal of sewage and a treatment process for denitrification and carbon removal of sewage. Background technique [0002] With the continuous increase of my country's population and the rapid development of industrial and agricultural production, the discharge of human production and domestic sewage is increasing, and a large number of environmental pollutants are discharged into water bodies, resulting in accelerated deterioration of the environment of receiving water bodies. In recent years, my country's waters The eutrophication of the environment is showing a trend of accelerating deterioration. The eutrophication of surface water has become one of the core problems of water pollution in my country, and the discharge of a large amount of nitrogen-containing sew...
