CLEANING METHOD OF CONTAMINATED SOIL

摘要

PROBLEM TO BE SOLVED: To provide a cleaning method of contaminated soil, wherein the cleaning period is shortened. SOLUTION: A soil cleaning fluid is injected into soil, and underground water in soil G is sucked in vacuum from a position different from the position injected with the cleaning fluid. This can promote infiltration (moving) speed of the cleaning fluid injected into the soil G to shorten a cleaning period. It is particularly effective when the water permeability of the contaminated soil is low. COPYRIGHT: (C)2008,JPO&INPIT
