METHOD AND SYSTEM FOR TREATING CONTAMINATED SOIL

摘要

PROBLEM TO BE SOLVED: To provide a method and a system for treating contaminated soil by which contaminated soil can be treated inexpensively in a short period of time and contaminants remaining in contaminated soil can effectively be decomposed continuously even after treated. SOLUTION: This method for treating contaminated soil comprises: a step 110 of mixing a nutrient for activating a microbe having oil content decomposing ability in contaminant-containing contaminated soil; a step 120 of mixing an improving material containing unslaked lime or a lime-based chemical in the contaminated soil where the nutrient is mixed at the step 110; and a step 130 of burying the soil treated by mixing the nutrient and the improving material respectively at the steps 110, 120 in the dug contaminated soil.
