METHOD FOR TREATING SOIL OR THE LIKE CONTAMINATED WITH ORGANIC CHLORINE COMPOUND

Document Type and Number:

Japanese Patent JP2004202290

Kind Code:

A

Abstract:

To provide a method for treating soil or the like contaminated with an organic chlorine compound which efficiently removes the organic chlorine compound.

Conductive microparticles and a hydroxide are kneaded with the soil contaminated with the organic chlorine compound to form a reaction layer, and the reaction layer is radiated with a microwave for dielectric heating, and then the organic chlorine compound is volatilized by heating the soil. Then, the organic chlorine compound thus volatilized is reduced in the reaction layer. As the hydroxide, iron hydroxide is preferable, and as the conductive microparticle, iron powder is preferable. By the above method, the organic chlorine compound is efficiently removed.
