Device for fast detecting microorganism electricity generation ability

Abstract

The invention provides a device for detecting microbial electricity generation capacity rapidly, which pertains to the field of microbial fuel cells, the structure of the device is that a lower layer polycarbonate plate, a silica gel pad, a titanium sheet, a carbon paper, a proton membrane, the carbon paper, the titanium sheet, the silica gel pad, an upper layer polycarbonate plate are sequentially stacked from top to bottom and are fastened together by fastening bolts; a butyl rubber plug is tightly pressed on the upper layer polycarbonate plate by the polycarbonate plate for sealing a roundhole at the center of the upper layer polycarbonate plate, a top layer polycarbonate plate and other components are fastened by the fastening bolts; and the components which are fastened together arearranged in a planar dish containing potassium ferrocyanide. The parts of the fastening bolts and the nuts for fastening the upper layer polycarbonate plate, the lower layer polycarbonate plate and all the middle layers are arranged in the corresponding through holes of the top layer polycarbonate plate. The device of the invention can detect the microbial electricity generation capacity within 5hours; compared with the existing detection method, the efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of microbial fuel cells, in particular to a device for rapidly detecting the electricity production capacity of microorganisms. Background technique [0002] Microbial fuel cell (MFC for short) is a special fuel cell that uses electricity-producing microorganisms as biocatalysts to directly convert the chemical energy of the anode fuel into electricity. It is applied in the field of sewage treatment, integrating electricity production and Sewage purification as a whole has very bright and attractive application prospects. [0003] Electrogenic microbes are the core of microbial fuel cells. However, there are less than ten species of electrogenic microbes that have been purified and isolated. One of the key reasons is the long detection cycle, which severely restricts further research on the anode electricity generation process and mechanism. . [0004] There are 15 Chinese patents on microbial fuel cells, "An electr...
