CONTAMINATED SOIL TREATMENT METHOD
To provide a contaminated soil treatment method that enables efficient reuse of contaminated soil.SOLUTION: A contaminated soil treatment method includes: a registration step of measuring a content of soil components and an elution amount of harmful substances for contaminated soil and registering at least the content of soil components in a database 32; an insolubilization treatment step of insolubilizing contaminated soil in which the elution amount of harmful substances exceeds a second elution amount standard larger than a soil elution amount standard, so that the elution amount of harmful substances is not more than the second elution amount standard; and a control step of when the elution amount of harmful substances exceeds the soil elution amount standard, carrying the contaminated soil after the insolubilization treatment to a specific location including a site of a cement factory 20 and storing the contaminated soil thereon, and when the elution amount of harmful substances is not more than the soil elution amount standard, storing the contaminated soil in situ 10 or carrying the same to the specific location, and registering the storage location of the contaminated soil in the database 32 and controlling the same. Contaminated soil is selected using the database 32 to be used as a raw material in cement production.SELECTED DRAWING: Figure 1
【課題】汚染土壌を効率よく再利用することを可能にする汚染土壌処理方法を提供する。【解決手段】汚染土壌について土壌成分の含有量及び有害物質の溶出量を測定し、少なくとも土壌成分の含有量をデータベース３２に登録する登録工程と、有害物質の溶出量が土壌溶出量基準より大きい第二溶出量基準を超える汚染土壌に対し、有害物質の溶出量が第二溶出量基準以下となるように不溶化処理を行う不溶化処理工程と、不溶化処理後の汚染土壌を、有害物質の溶出量が土壌溶出量基準を超える場合はセメント工場２０の敷地を含む特定位置に搬出して保管し、土壌溶出量基準以下の場合は原位置１０で保管又は特定位置に搬出して保管すると共に、汚染土壌の保管位置をデータベース３２に登録して管理する管理工程とを有し、データベース３２を用いて汚染土壌を選定し、セメント製造における原料として用いる。【選択図】図１
