Abstract

The invention provides a large-diameter porous spacing structure used in a biological-cathode microorganism electrochemical system, and relates to a large-diameter porous spacing structure in an electrochemical system. The invention aims to solve the problem of high cost of a spacing material in an existing microorganism electrochemical system. The porous spacing structure main body is in a plateshape or a cylindrical shape and comprises at least one layer of large-diameter porous spacing material, at least one layer of insulation material is arranged in the large-diameter porous spacing material in the structure main body, holes of the large-diameter porous spacing material are opened holes, and the diameters of the holes are 0.1 micrometer to 5 millimeters. The spacing structure is usedfor partitioning a cathode chamber and an anode chamber, the structure has seepage water through capability, and oxygen dissolution between the cathode and the anode at two sides, COD gradient and negative / positive ion conduction capability are maintained; compared with an ion / proton exchange membrane, the structure has the advantage that very low cost can be achieved; and the large-diameter porous spacing structure is suitable for the biological-cathode microorganism electrochemical system.

Description

technical field [0001] The invention relates to a large-diameter porous spacer structure in an electrochemical system. Background technique [0002] The microbial electrochemical system is a device that can directly convert the chemical energy in organic matter into electrical energy by using the catalytic action of microorganisms. In the microbial electrochemical system, the microorganisms in the anode metabolize the organic or inorganic substances in the wastewater, transfer the electrons to the anode electrode, the electrons are conducted to the cathode through the external circuit, and the electrons in the cathode pass through the external circuit and the electron acceptor O 2 Combined, protons migrate from the solution from the anode to the cathode, thus forming a closed loop and completing the reaction process. The biocathode microbial electrochemical system refers to the attachment of microorganisms on the surface of the cathode, obtaining electrons from the electrod...
