Abstract
The invention discloses a denitrification anaerobic methane oxidation membrane bioelectrochemical reaction device and its method. The device includes a closed cylinder and a cathode and an anode located in the inner cavity of the cylinder. The positive electrode is connected; the anode includes titanium mesh, granular activated carbon and MBR membrane module, and the titanium mesh wraps the granular activated carbon on the surface of the MBR membrane module; the surfaces of the granular activated carbon and the MBR membrane module are both used to enrich denitrifying anaerobic methane oxidizing microorganisms; The cathode is a carbon felt surface used to enrich autotrophic denitrifying microorganisms; a water distribution pipe with uniform openings is provided in the inner cavity of the cylinder below the anode and cathode, and a gas distributor is provided under the water distribution pipe. The invention realizes the synergistic removal of nitrate and methane in the waste water treatment process through the coupling of the bioelectrochemical system, the membrane module and the denitrifying anaerobic methane oxidizing microorganism, and has the characteristics of high efficiency, low cost, low energy consumption and small 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: ...
