摘 要：Abstract：The invention provides an electrochemistry flushing method and an electrochemistry flushing device for contaminated soil. The flushing remediation and synchronous treatment of flushing solution for the contaminated soil are realized by using electrochemistry reaction products and the process. A main body of the device comprises an electrode chamber 1, an electrode chamber 4 and a soil chamber 3, wherein the electrode chamber 1 is of a closed structure; the air pressure of the electrode chamber 1 is raised by gases generated on an electrode 2 and presses the flushing solution into the soil to form a flushing process; OH<->(or H<+>) ions generated on the electrode 2 enter the soil to promote the desorption of heavy metal ions and organic pollutants; the power-on electric heating effect is required to raise the temperature of the soil and promote the desorption of the pollutants; the heavy metal ions, the organic pollutants and the OH<->(or H<+>) ions which are flushed to the electrode chamber 4 react with Fe<2+>(or OH<->) ions generated on an electrode 5, and are reduced or form precipitations; the flushing solution in the electrode chamber 4 is pumped into a mud-water separator 6 for separating the precipitations and then the flushing solution is returned to the electrode chamber 4, so that the synchronous treatment of the flushing solution is realized.
