Abstract

The invention relates to an overlapped microbial fuel cell in-situ test system and an application thereof. The overlapped microbial fuel cell in-situ test system comprises a positive electrode chamber formed by at least one positive electrode reaction module in a series-wound overlapping manner, a negative electrode chamber formed by at least one negative electrode reaction module in a series-wound overlapping manner, a proton exchange membrane arranged between the positive electrode chamber and the negative electrode chamber, and a circumscribed nitration reactor communicated with the positive electrode chamber and the negative electrode chamber separately; the positive electrode chamber and the negative electrode chamber are arranged oppositely in the mode of an upper one and a lower one that can be exchanged mutually; and a circumscribed adjustable resistive circuit is further arranged between the positive electrode chamber and the negative electrode chamber. The system is used for in-situ test on the characteristic parameters of the electrode biological membrane under the same electrochemical state. Compared with the prior art, the overlapped microbial fuel cell in-situ test system is simple and compact in structure; the functions of decarbonization, nitration and denitrification are arranged in independent units; the pollutant removal efficiency is improved; the system can be changed easily according to the pollutant concentrations and actual water amount; and the overall system is high in sealing property, high in stability, stable in running, and wide in the development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of bioelectrochemistry, and relates to an in-situ test system for a stacked microbial fuel cell and its application. Background technique [0002] Microbial fuel cells (MFCs) have attracted increasing attention due to their economical and environmentally friendly properties of sustainable recovery of electricity while treating pollutants. In MFC, the anode and cathode are connected by conductive materials, and the organic matter is oxidized by electrogenic microorganisms in the anode chamber to generate electrons, which are transferred to the anode electrode and flow to the cathode through an external circuit, and are finally utilized by the reducible compounds in the cathode chamber. The application of MFC to the removal of various organic matter in wastewater has been widely reported. MFC can not only degrade organic matter into electrical energy, but also use nitrate and sulfate as electron acceptors of ...
