DISPOSAL METHOD AND DISPOSAL SYSTEM OF EXCAVATED SOIL
PROBLEM TO BE SOLVED: To provide a disposal method of excavated soil capable of disposing excavated soil by insolubilizing a toxic substance by a novel method.SOLUTION: A disposal method of excavated soil containing a toxic substance comprises an oxidation reduction potential regulation step of mixing an oxidation reduction potential regulator regulating an oxidation reduction potential and excavated soil to regulate an oxidation reduction potential of the excavated soil, and a pH regulation step of mixing a pH regulator regulating pH to regulate pH of the excavated soil. The oxidation reduction potential of the excavated soil is regulated by the oxidation reduction potential step, and the pH of the excavated soil is regulated by the pH regulation step to cause the toxic substance in the excavated soil to be absorbed easily by any other substances.SELECTED DRAWING: Figure 13
【課題】新規な方法で有害物質を不溶化して掘削土を処理する掘削土の処理方法を提供する。【解決手段】有害物質を含む掘削土を処理する処理方法であって、酸化還元電位を調整する酸化還元電位調整剤を掘削土に混合して、掘削土の酸化還元電位を調整する酸化還元電位調整工程と、pHを調整するpH調整剤を混合して、掘削土のpHを調整するpH調整工程と、を備える。酸化還元電位工程によって、掘削土の酸化還元電位が調整され、pH調整工程によって、掘削土のpHが調整され、掘削土中の有害物質が他の物質に吸着され易くする。【選択図】図13
