<P>PROBLEM TO BE SOLVED: To provide a method for purifying soil pollution that can efficiently purify polluted soil in situ by uniform penetration of a chemical liquid into the soil in a short period of time. <P>SOLUTION: In the method for purifying soil pollution, the linear feed velocity of the chemical liquid 5 to the soil 1 is equal to or less than the saturated hydraulic conductivity of the soil 1, and gas 6 is supplied to the soil 1 substantially simultaneously with the chemical liquid 5. In the method for purifying soil pollution, a method may be used in which the supply pressure of the chemical liquid 5 to the soil 1 is equal to or less than the soil suction pressure and the gas 6 is supplied to the soil 1 substantially simultaneously with the chemical liquid 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
