The iron-carbon (Fe/C) micro-electrolysis method was used to dispose trichloroethylene (TCE) and tetrachloroethylene (PCE) of polluted groundwater, and several factors such as the mass ratio of Fe/C, the characteristics of activated carbon, the particle size of iron powder and influent pH were investigated. The optimal conditions were acquired. The mass ratio of Fe/C was 1:1, coconut shell charcoal and 30-mesh iron powder were used, and influent pH was 5. Under the optimal conditions, mixed solution of TCE and PCE was treated by Fe/C micro-electrolysis method and the tests got 82.4% of the TCE removal rate and 59.4% of the PCE removal rate.
