Galvanic cell device for repairing chromium-contaminated soil based on microorganism-organic matter and repairing method of galvanic cell device

The invention discloses a primary battery device for repairing chromium-polluted soil based on microbial organic matters and a repairing method thereof. The invention relates to a galvanic cell devicefor repairing chromium-contaminated soil based on microorganism-organic matter and repairing method of galvanic cell device, anaerobic sludge containing electrogenesis microorganisms in the device ismixed with organic matter to generate electrons, the electrons are transmitted through an electrode material and an electron transmission path to repair Cr in chromium-contaminated soil, metabolism of the electrogenesis microorganisms is improved through K induction in a salt bridge, activation of chromium is promoted, and the chromium-contaminated soil remediation effect is improved, an organic acid leacheate is added, microorganisms can be promoted to adsorb and convert part of Cr in the soil; a mixture of organic matters and anaerobic sludge is taken out and mixed with the remediated contaminated soil, c
