SOIL WASHING SYSTEM FOR POPS AND HEAVY METALS CONTAMINATED SOILS

摘要

PURPOSE: A method for washing and restoring soil contaminated with heavy metal and residual organic compounds is provided to wash soil without effects of conditions of the soil to be washed by adjusting reaction time of the soil. CONSTITUTION: A method for washing and restoring soil contaminated with heavy metal and residual organic compounds includes the following steps: supplying soil(S10); screening the soil which is 30mm or more(S20); washing soil and foreign materials by friction, separation, mixing, and pulverizing(S30); restoring the soil and separating foreign materials by dehydrating the separated soil with a first dehydrating vibration screen(S40); collecting water and soil of 1 mm or less in a cyclone(S50); separating contaminants(S60); and restoring the soil by dehydrating soil of 0.075 mm or more(S70).
