Abstract
The present invention provides a microbial electrolysis cell and a method for treating uranium-containing wastewater. The microbial electrolysis cell comprises an electrolysis cell; an electrolyte solution and uranium-containing wastewater are disposed within the electrolysis cell; a bioanode and a biocathode disposed within the electrolysis cell; and an external circuit connecting the bioanode and the biocathode. The microbial electrolysis cell is used to perform microbial electrochemical reduction of the uranium-containing wastewater. Compared with existing technologies, the present invention utilizes a microbial electrolysis cell to treat uranium-containing wastewater. This cell can reduce hexavalent uranium ions to a relatively low concentration by applying a relatively low external voltage, and has a wide pH range of applicability. Furthermore, the establishment of a biocathode accelerates the treatment of uranium-containing wastewater, improves treatment efficiency, and reduces operating costs. Furthermore, the microbial electrolysis cell can produce a large amount of hydrogen while treating the uranium-containing wastewater.
