Title
(EN) A REMEDIATION METHOD OF CONTAMINATED MATERIALS BY USING ZEOLITE ANCHORED NANOSCALE IRON CONTAINING REACTIVE WALL
(FR) PROCEDE DE DECONTAMINATION DE MATERIAUX PAR L'UTILISATION DE FER A ZEOLITE ANCREE A L'ECHELLE NANOMETRIQUE DANS UN MUR REACTIF
Abstract
(EN)
The present invention relates to a remediation method of contaminated materials by using zeolite anchored nanoscale iron comprising the steps of making a reactive wall including zeolite anchored nanoscale iron and installing the reactive wall at the place where contaminate materials pass, and eliminating contaminant by passing contaminated materials through the reactive wall. According to this invention, the remediation of organic chlorides by granular iron and remediation of heavy metals and nutrient salts by zeolite can be carried out in a single reactive wall system.
(FR)
L'invention concerne un procédé de décontamination de matériaux par l'utilisation de fer à zéolite ancrée à l'échelle nanométrique. Ce procédé comprend les opérations suivantes : créer un mur réactif comportant du fer à zéolite ancrée à l'échelle nanométrique ; installer ce mur réactif à l'endroit où passent les matériaux contaminés ; éliminer les contaminations en faisant passer les matériaux contaminés à travers le mur réactif. Selon l'invention, l'élimination de chlorures organiques au moyen de granulés de fer et l'élimination de métaux lourds et de sels nutritifs au moyen de la zéolite peuvent être réalisées grâce à un seul et même système de mur réactif.
