Abstract: The present disclosure discloses a method for removing chlorinated hydrocarbons in groundwater through step-by-step electrocatalytic dechlorination degradation. A double-chamber electrolyzer reactor is used to carry out step-by-step electrocatalytic dechlorination degradation to remove chlorinated hydrocarbons in groundwater. The double-chamber electrolyzer reactor comprises a cathode chamber, a proton exchange membrane, an anode chamber and an intermediate processing unit, wherein the cathode chamber is separated from the anode chamber through the proton exchange membrane, and the intermediate processing unit is connected between the cathode chamber and the anode chamber through a cathode chamber water outlet, an anode chamber water inlet and pipelines.
