Abstract

The invention discloses a denitrification anaerobic methane oxidation film bioelectrochemical reaction device and method, wherein the device comprises a closed cylinder and a cathode and an anode which are located in an inner cavity of the cylinder, and the cathode and the anode are respectively communicated with a negative electrode and a positive electrode of an external power supply through wires; the anode comprises a titanium mesh, granular activated carbon and an MBR membrane assembly, and the titanium mesh wraps the granular activated carbon on the surface of the MBR membrane assembly;the surfaces of the granular activated carbon and the MBR membrane assembly are used for enriching denitrification anaerobic methane oxidation microorganisms; the cathode is a carbon felt of which thesurface is used for enriching autotrophic denitrification microorganisms; a water distribution pipe with uniform holes is arranged in the inner cavity of the cylinder below the anode and the cathode,and a gas distributor is arranged below the water distribution pipe. Through coupling of a bioelectrochemical system, the membrane assembly and the denitrification anaerobic methane oxidation microorganisms, synergistic removal of nitrate and methane in the wastewater treatment process is achieved, and the device has the advantages of being high in efficiency, low in cost, small in energy consumption and small in space.

Description

technical field [0001] The invention belongs to the field of wastewater biological treatment, and in particular relates to a denitrification anaerobic methane oxidation film bioelectrochemical reaction device and a method thereof. Background technique [0002] The nitrification-denitrification process of traditional wastewater biological denitrification has insufficient electron donors in the denitrification section, which restricts the denitrification efficiency. To the atmosphere, it is one of the main causes of the global greenhouse effect, and it is also a waste of resources. Contents of the invention [0003] The invention provides a denitrification anaerobic methane oxidation film bioelectrochemical reaction device and a method thereof, aiming at problems such as incomplete denitrification process and disorderly discharge of generated methane in urban wastewater treatment. [0004] The technical scheme that the present invention specifically adopts is as follows: ...
