In the soil which was contaminated with in situ purification mannered null chlorinated organic compound

摘要

PPROBLEM TO BE SOLVED: To provide a method for efficiently cleaning soil contaminated with organic chlorine compounds in situ without digging. PSOLUTION: The method for cleaning the soil contaminated with organic chlorine compounds in situ includes a process in which stirring blades mounted to two or more rotating shafts are made to penetrate into the soil contaminated with the organic chlorine compounds, and iron fine particle slurry is added to the soil, and then the soil to which the iron fine particle slurry is added is stirred with the stirring blades. The stirring blades are simultaneously rotated in the normal direction and the reverse direction. PCOPYRIGHT: (C)2005,JPO&NCIPI
