PURIFYING METHOD OF AQUIFER
PROBLEM TO BE SOLVED: To provide a technique capable of purifying an aquifer contaminated with harmful substances even in the case where injection of fluid for purification is difficult.SOLUTION: A purifying method of a low water permeable aquifer contaminated with harmful substances comprises: a process 1 of connecting a vacuum pump to a well which is installed in a low water permeable aquifer contaminated with harmful substances in an airtight state, pumping up groundwater which exists in the aquifer to reduce a water level of the groundwater, forming an unsaturated layer in the aquifer, and allowing air to contact soil which exists in the unsaturated layer; and a process 2 of feeding oxygen, nutrient or water to the unsaturated layer after the process 1.SELECTED DRAWING: None
【課題】浄化用流体の注入が困難な場合においても、有害物質で汚染された帯水層を浄化することができる技術を提供する。【解決手段】有害物質で汚染された低透水性の帯水層に設置した井戸に真空ポンプを気密状態で接続し、前記帯水層に存在する地下水を揚水して前記地下水の水位を低下させ、前記帯水層に不飽和層を形成し、前記不飽和層に存在する土壌に空気を接触させる工程１と、前記工程１の後、前記不飽和層に酸素、栄養剤又は水を供給する工程２と、を備える、有害物質で汚染された低透水性の帯水層の浄化方法。【選択図】なし
