SYSTEM FOR REMEDIATION OF CONTAMINATED SOIL AND UNDERGROUND WATER

摘要

PROBLEM TO BE SOLVED: To provide a system for remediation of contaminated soil and underground water capable of prohibiting an agent from flowing out to the outside of a site, and capable of efficiently diffusing the agent all over the site.;SOLUTION: The system for remediation of contaminated soil and underground water comprises: clarifier feeding means 14 for feeding water containing a clarifier for clarifying a contaminant such as an aqueous solution containing a contaminant-decomposing micro-organism; a water-impervious outside wall 11 constructed so as to circumscribe the surrounding of a ground 2 including a contaminated region K and a water-permeable layer 4; an injection well 13, provided inside the water-impervious outside wall 11, for injecting water containing the clarifier which clarifies the contaminant in the water-permeable layer 4; a pumping well 17 for pumping up groundwater confined in the water-impervious outside wall 11; and a water-impervious inside wall 12 for forming a flow path to flow ground water from a place provided with the injection well 13 to a place provided with the pumping well 17.;COPYRIGHT: (C)2015,JPO&INPIT
