TREATMENT METHOD OF EXCAVATION MUCK
PROBLEM TO BE SOLVED: To provide a treatment method to be applied in the case excavation muck contains heavy metals and the like, for insolubilizing heavy metals and the like contained in the excavation mud, efficiently and sufficiently.SOLUTION: A treatment method of excavation muck comprises: a liquid supply step for supplying an aqueous liquid to material to be treated comprising excavation muck or crushed excavation muck to increase a surface moisture of particles constituting the material to be treated; and an insolubilization step for adding an insolubilization material comprising a magnesium oxide-containing substance to insolubilize harmful substances contained in the material to be treated.SELECTED DRAWING: None
【課題】掘削ずりが重金属類等を含む場合に、掘削ずりに含まれている重金属類等を、簡易にかつ十分に不溶化するための処理方法を提供する。【解決手段】掘削ずり、または、該掘削ずりを破砕してなる掘削ずり破砕物からなる処理対象物に、水性の液体を供給して、上記処理対象物を構成する粒体の表面水率を増大させる液体供給工程と、上記水性の液体を供給した後の上記処理対象物に、酸化マグネシウム含有物質からなる不溶化材を添加して、上記処理対象物に含まれている有害物質を不溶化する不溶化工程、を含む掘削ずりの処理方法。【選択図】なし
