PROBLEM TO BE SOLVED: To provide a contaminated soil purification method that can separate contaminants from soil more effectively than conventional purification methods.SOLUTION: Acidic electrolytic water 1 is supplied from the anode 5 side of a diaphragm electrolysis mechanism, alkaline electrolytic water 2 is supplied from the cathode 8 side of the diaphragm electrolysis mechanism, and soil contaminated with harmful substances is treated with the acidic electrolytic water 1 and then treated with the alkaline electrolytic water 2. A process may be provided in which the treatment water is applied to a screen 12 and soil water passing through the screen 12 is acidified to precipitate soil. |
