Abstract

The present application relates to a method for treating contaminated soil comprising a steaming process, and to an apparatus for same. More particularly, the present invention relates to a method for treating contaminated soil in which a steaming process is added to a restoring process for restoring contaminated soil discharged from a petroleum-contaminated area into loam, in order to lower the viscosity of the petroleum components attached to the contaminated soil, and to thus desorb the petroleum components and to collect the desorbed petroleum components in the upper portion of the apparatus, wherein strong air is blown into the apparatus to scatter the desorbed petroleum components in the upward direction and to discharge the petroleum components through a duct. The present invention also relates to an apparatus for same. The present application discloses a technical idea regarding a method for restoring contaminated soil, wherein contaminated soil restoring means provided by the present application collects contaminated objects to be restored and treats the collected objects in a steam-heating desorption tank. The steam-heating desorption tank has an outer body with steam supply means and air supply means, and an interior with stirring means, wherein the steam-heating desorption tank stirs the contaminated object introduced therein while steaming the contaminated object for 10 to 30 minutes at high temperature and high pressure conditions in which the steam-heating desorption tank has an internal pressure of 1.1 to 3.5 kgf/cm2, based on 1 atmospheric pressure marked as 1.01325 kgf/cm2, in order to prepare a condition in which the petroleum components attached to the contaminated object can be easily desorbed. Subsequently, strong air is supplied to the tank all at once to desorb the petroleum components. Thus, the petroleum components are desorbed from the contaminated object and discharged to the outside together with the air.
