Abstract

The invention provides a novel membrane bioreactor-microbial fuel cell coupling system, relates to the fields of water treatment and new energy, and aims at solving the technical problems that existing microbial fuel cells are low in power generation amount and poor in effluent water quality. The filtration behavior of an anode membrane module can reduce the loss of anode microorganisms, increasethe concentration of microorganisms, improve the quality of effluent water, enhance the migration of microorganisms to electrodes, and accelerate electron extraction; the filtration behavior of a cathode can make the passive diffusion mass transfer between oxygen and electrodes change into active enhancement mass transfer, and therefore an electrode reaction is strengthened. The provided membranebioreactor-microbial fuel cell coupling system has a simple working process and convenient operation.

Description

technical field [0001] The invention belongs to the fields of water treatment and new energy, and in particular relates to a novel membrane bioreactor-microbial fuel cell coupling system. Background technique [0002] The membrane bioreactor replaces the secondary sedimentation tank in the traditional biochemical treatment technology by microfiltration or ultrafiltration membrane filtration. It has the advantages of stable system operation, simple process, high treatment efficiency, good effluent quality, and small equipment footprint. At present, the important problems that hinder the rapid development and large-scale application of membrane bioreactors are the decrease of working efficiency caused by membrane fouling, the increase of operating costs and the high energy consumption of the aeration process. Microbial fuel cell is a device that converts chemical energy contained in organic matter into electrical energy by using the catalysis of electrochemically active microo...
