Title (EN) SYSTEM AND METHOD FOR REMEDIATION OF ORGANIC CONTAMINATED SOIL
(FR) SYSTÈME ET PROCÉDÉ POUR L'ASSAINISSEMENT D'UN SOL CONTAMINÉ ORGANIQUE
(ZH) 一种有机污染土壤修复系统与方法
Abstract:
(EN) A system and a method for remediation of organic contaminated soil are provided, which comprises M*N electrodes to form an electrode matrix of symmetrical electric field structure. The field intensity is uniform in those points that are equidistant from each electrode in remediation area. The electrodes arrayed in mesh style in remediation area are carried out electrokinetic remediation. To exchange between positive polarity and negative polarity of the electrodes periodically is to make each electrode be a state of anode intermittently which has preferable remediation efficiency, by operation mode of reversing row/column electrode groups in manner of electrical scanning.
(FR) L'invention porte sur un système et sur un procédé pour l'assainissement d'un sol contaminé organique, lesquels comprennent M*N électrodes pour former une matrice d'électrodes ayant une structure de champ électrique symétrique. L'intensité de champ est uniforme dans les points qui sont équidistants de chaque électrode dans la zone d'assainissement. Les électrodes groupées selon un mode de treillis dans la zone d'assainissement effectuent un assainissement électrocinétique. Pour un échange entre une polarité positive et une polarité négative des électrodes, il est fait en sorte, périodiquement, que chaque électrode soit à un état d'anode par intermittence, ce qui a une efficacité d'assainissement préférable, par un mode de fonctionnement d'inversion de groupes d'électrodes de rangée/colonne à la façon d'un balayage électrique.
