PROBLEM TO BE SOLVED: To surely and uniformly purify underground water or soil polluted with volatile organic chlorine compounds. SOLUTION: In the subject purification method for the volatile organic chlorine compounds related to the present invention, the compounds are drawn out of an agitation region 6 while reversely rotating a hollow agitator shaft 1 and agitation blades 4. In this drawing process, activated carbon-iron adhered body 32 conveyed through a conveying space in the shaft 1 is jetted from discharge ports 31 provided in the blades 4. By this operation, the chlorine compounds contained in a polluted region 3 is first adsorbed to power of the activated carbon constituting the activated carbon-iron adhered body 32 to purify the polluted region 3. The chlorine compounds are made harmless by iron constituting the activated carbon-iron adhered body 32 after adsorption. COPYRIGHT: (C)2005,JPO&NCIPI |
