Title:
METHOD AND DEVICE FOR ELECTROCHEMICALLY DOMESTICATING ANAEROBIC AMMONIA OXIDIZING BACTERIA
Document Type and Number:
WIPO Patent Application WO/2023/035339
Kind Code:
A1
Abstract:
A method and device for electrochemically domesticating anaerobic ammonia oxidizing bacteria, relating to the technical field of water treatment. The device comprises a reactor body, a water inlet system connected to the reactor body by means of a pipeline, and a sludge backflow device connected to the reactor body by means of a pipeline, wherein the reactor body comprises a microbial electrochemical reactor (23), and an anode carbon fiber brush (9), a reference electrode (12), and a cathode carbon fiber brush (11) are provided in the microbial electrochemical reactor (23). Carbon fibers having good electrical conductivity, good biocompatibility, economy and environmental protection are used as a biofilm carrier, and a microbial electrochemical principle is applied, such that the activity of the anaerobic ammonia oxidation bacteria is enhanced, the starting time of an anaerobic ammonia oxidation process is shortened, and long-term stable operation is realized.
