ELECTROKINETIC REMEDIATION APPARATUS FOR ANIONIC CONTAMINANT USING SACRIFICIAL ANODE

摘要

PURPOSE: An electrokinetic meditation apparatus for anionic contaminants using a sacrificial anode is provided to purify the anionic contaminants in soil polluted with the anionic contaminants without a separate basic electrolyte processing for changing the pH of the entire soil to the basic condition, by removing hydrogen ions generated in an anode. CONSTITUTION: An electrokinetic meditation apparatus for anionic contaminants comprises an anode(20), a cathode(30), an anode electrolyzer(50), and a cathode electrolyzer(52). The anode and cathode are positioned on both sides of soil polluted with the anionic contaminants, and form an electric field on the contaminated soil. An anode-electrolyte and an cathode-electrolyte for supplying electrolytes to the anode and cathode are respectively stored in the anode electrolyzer and cathode electrolyzer, respectively. The anode itself is oxidized and is made of components consisting of the soil. A sacrificial anode is any one selected from iron, aluminum, or their alloys. The sacrificial anode is a bent form or has scratches on the surface. [Reference numerals] (AA) Polluted soil
