Device for treating organic pollutants in underground water

The utility model provides a device for treating organic pollutants in underground water. The device comprises an electric power unit and a permeable reactive barrier unit, wherein the electric powerunit comprises a power supply, a cathode and an anode, the cathode and the anode are respectively connected with a cathode and an anode of the power supply, the cathode and the anode are arranged in parallel at an interval, and the cathode and the anode are vertically arranged underground; wherein the permeable reactive barrier unit is arranged around the cathode, and the permeable reactive barrier filling material is iron and ethylenediamine tetraacetic acid mixed particles. According to the utility model, the groundwater remediation effect is enhanced by combining the electrodynamic force and the permeable reactive barrier technology; a novel filling material is adopted, so that the rate of reducing organic pollutants is increased, the treatment period is shortened, and the removal rateof organic matters can rea
