TREATMENT METHOD OF DREDGED SOIL
To provide a treatment method of dredged soil that can suppress the elution of organic matter from improved dredged soil after solidification treatment and can prevent excessive hardening and strong alkalization of solidification-treated soil while ensuring the strength of solidification-treated soil.SOLUTION: The treatment method of dredged soil is a treatment method of dredged soil for suppressing the elution of organic matter from dredged soil and includes: an organic matter amount measurement step of measuring a content of organic matter in the dredged soil; and a dredged soil improvement step of adding a calcium silicate-containing granular material to the dredged soil and mixing therewith and performing no ozone treatment to obtain improved dredged soil when the content of organic matter is a predetermined specific value or less or adding a calcium silicate-containing granular material to the dredged soil and mixing therewith, followed by adding water to increase a moisture content and then performing ozone treatment to obtain improved dredged soil when the content of organic matter exceeds a predetermined specific value.SELECTED DRAWING: None
【課題】固化処理後の改良された浚渫土からの有機物の溶出を抑制することができ、かつ、固化処理土の強度を確保しながら、固化処理土の過度の硬化および強アルカリ性化を防ぐことができる浚渫土の処理方法を提供する。【解決手段】浚渫土からの有機物の溶出を抑制するための浚渫土の処理方法であって、上記浚渫土中の有機物の含有率を測定する有機物量測定工程と、上記有機物の含有率が、予め定めた特定の値以下である場合、上記浚渫土にケイ酸カルシウム含有粉粒状物を添加して混合し、かつ、オゾン処理を行わずに、改良された浚渫土を得て、上記有機物の含有率が、上記予め定めた特定の値を超える場合、上記浚渫土にケイ酸カルシウム含有粉粒状物を添加して混合し、次いで、水を加えて含水比を高めた後に、オゾン処理を行って、改良された浚渫土を得る浚渫土改良工程、を含む浚渫土の処理方法。【選択図】なし
