Reclamation process of contaminated rock medium by employing in-situ chemical oxidation method

摘要

Method of remediation contaminated ground by in-situ chemical oxidation comprising applying an aqueous permanganate solution directly into the contaminated ground, so that at least partial chemical destruction of contaminants present. The volume of permanganate in the present method is intentionally selected so that far exceed the stoichiometrically required amount for oxidizing contaminants located in the rock medium, thereby in addition to the oxidation of these contaminants also be achieved by additional sorption effect when the other part of the contaminants may be sorbed on precipitated oxides and / or hydroxides manganu.Vynález is industrially useful in the correction of environmental damage, especially then when in-situ remediation of contaminated soil and contaminated groundwater.
