The invention discloses a repair method of cadmium and lead polluted soil and an electric-microorganism united permeable reaction wall repair device. The device comprises a reaction tank, an electrode, a power supply and permeable reaction walls, space between the two permeable reaction walls is filled with to-be-treated cadmium and lead polluted soil added with microorganisms, pollutants which are migrated to an electrode from the soil are adsorbed by the permeable reaction walls, and therefore, heavy metals including cadmium and lead are removed from the to-be-treated soil. The soil is repaired by uniting the microorganisms, an ecological adsorption material and electrodynamics, a plurality of methods are used, a plurality of systems are used in an integrated manner, the pollutants which are transferred to two poles are adsorbed and fixed through PRB, so that the heavy metals are removed from the soil, by use of the permeable reaction walls and an electric method, an electric pollutant extracting system is omitted, the repair method is close to reality, and the repair performance of an electrokinetic system is optimized. By the method, soil repair period is short, cost is low, efficiency of repair to the cadmium and lead polluted soil is high, and secondary pollution is not caused easily.
