Abstract

The invention discloses a cathode efficient denitrification type microbial fuel cell with coupling anaerobic ammonium oxidation technologies. The cathode efficient denitrification type microbial fuel cell comprises an anode electrochemical active bacterium carbon removal system, a cathode anaerobic ammonium oxidation bacterium denitrification system, an external circuit and data on-line acquisition system, an anaerobic closed sampling system, a pressure stabilizing system and a magnetic stirring system. Compared with the traditional cathode denitrification type MFC (microbial fuel cells), the cathode efficient denitrification type microbial fuel cell has the advantages that the cathode efficient denitrification type microbial fuel cell can run intermittently and is simple in device structure; obvious denitrification effects can be realized, nitrogen load can be obviously increased, excellent electricity generation effects can be realized, the practicality can be greatly improved, and novel application can be developed for microbial fuel cells and anaerobic ammonium oxidation technologies.

Description

technical field [0001] The invention belongs to the technical field of microbial electrochemical systems, and in particular relates to a cathode high-efficiency denitrification microbial fuel cell coupled with anaerobic ammonia oxidation technology. Background technique [0002] In recent years, with the expansion of industrial scale and the intensification of human activities, the nitrogen pollution in domestic sewage and industrial wastewater has shown a trend of increasing concentration and increasing discharge. The random discharge of wastewater with high nitrogen content not only easily causes water eutrophication , will also consume a large amount of dissolved oxygen in water, causing serious damage to the water environment. At the same time, due to the increasing shortage of energy sources, the energy consumption problem in the process of pollution control has gradually been paid attention to. The development of energy-saving processes and products is a key research d...
