Self-medium coupled microbe fuel battery for single room micro filtering
Technical field
The present invention relates to fuel cell, be particularly related to that a kind of cheapness, configuration are simple, easy operating, can be at the efficient self-medium coupled microbe fuel battery for single room micro filtering that obtain direct electric energy when handling organic sewage, this microbiological fuel cell also is a kind of sewage-treatment plant.
Background technology
The microbiological fuel cell technology of Xing Qiing can be obtained extra electric energy output when disposing of sewage in recent years, was the novel sewage treatment process outside a kind of continue traditional activated sludge process and the anaerobic digestion process.The microbiological fuel cell (MFC) that is used in early days study is a double chamber type, and yin, yang two electrodes lay respectively in cathode chamber and the anode chamber, in the middle of proton exchange membrane is positioned at.Be applied to actual waste water when handling, greatest problem is that the proton exchange membrane of putting under water can't be born big hydrostatic pressure, has also simultaneously that internal resistance is big, power output is low, negative electrode needs aeration, energy consumption is big and problem such as cost height.
Publication number is that the patent of invention technology of CN1874040A on December 6th, 2005 disclosed a kind of single chamber type MFC; has only an anode chamber; proton exchange membrane by hot pressing attached to cathode surface; though with respect to double chamber type MFC; its internal resistance is lower, configuration is simplified; but after the long-play, proton exchange membrane usually can be separated with negative electrode, cathode assembly useful life limited and processing and replacing program complexity.And in its normal course of operation,, be easy to take place problems such as leakage, besides proton exchange membrane cost costliness because negative electrode is bearing hydrostatic pressure always.
Can obtain higher electricity generation performance within a short period of time though in single chamber type MFC, remove proton exchange membrane, but because after the proton exchange membrane omission, negative electrode is directly exposed in the environment of anode microbe, will inevitably directly have influence on the catalytic performance of negative electrode.Especially when using actual waste water as matrix fuel, on the one hand, actual waste water often comprises the pollutant of various complexity, and these pollutants can make catalysqt deactivation with the cathod catalyst reaction; On the other hand, microbe can make also that in its surface attachment growth the performance of negative electrode reduces rapidly.
