CONTAMINATED SOIL CLEANUP METHOD

摘要

PROBLEM TO BE SOLVED: To provide a contaminated soil cleanup method for activating microbe over the whole area of a soil contaminated by harmful chemical materials and decomposing contamination materials by bio-decomposition reaction by the microbe.;SOLUTION: The contaminated soil cleanup method comprises: a borehole formation step for forming a borehole reaching to a contaminated soil; an injection device insertion step for inserting a rod to whose tip end an injection device is attached into the borehole; and a soil cut step for forming a planar-shaped area where the soil and a microbe activation agent are mixed and the soil is cut intermittently by the microbe activation agent by injecting the microbe activation agent from the injection device.;COPYRIGHT: (C)2015,JPO&INPIT
