The utility model relates to a two-dimensional EK-PRB device for heavy metal contaminated rice soil remediation, which comprises a direct-current power supply, an electrode, electrolyte and PRB activereaction materials, and is characterized in that the direct-current power supply is connected with the electrode through a wire; wherein the electrodes comprise four anodes and a cathode which are parallel to each other, the anodes are cylindrical stainless steel electrodes and are sequentially connected on the same horizontal plane according to the central points of the anodes to form a square,any anode is arranged in the porous PVC pipe, and the cathode is a porous stainless steel pipe electrode and is located at the central position of the square; the electrolyte is contained in the porous PVC pipe and the cathode; and the PRB active reaction material is arranged around the porous PVC pipe or the cathode. The cathode and the anode of the device are arranged in a square shape, so thatthe defects of short action distance and non-uniform electric field distribution of the cathode and the anode in the prior art are overcome, and the device has higher removal efficiency on deep pollutants.
