A method which can maximize the evaporation efficiency of volatile contaminants contained in underground water, can remediate soils as well as underground water, and can easily remediate underground water and soils event at a place with a low water content is provided. A method for separating oils by ultrasonic wave comprises: a field survey step of grasping accurate geological features and hydrogeological properties of contaminated ground; a perforated pipe laying step of laying a perforated pipe having a plurality of slotted holes formed on an outer peripheral surface thereof into a predetermined depth of a place that is most suitable for the surveyed ground state and contaminated area; a mounting step of inserting a connecting wire to which an oscillator is connected into the perforated pipe, wherein the oscillator emits a ultrasonic wave generated from a ultrasonic wave generator that can control the generation output of ultrasonic wave at a predetermined frequency when underground water is infiltrated into the laid perforated pipe; an evaporation step of allowing the ultrasonic wave to be outputted at a specific frequency through the oscillator to evaporate underground water and contaminants; and an exhaust step of separating contaminants from evaporated exhaust gas, and releasing the evaporated exhaust gas except the contaminants into the atmosphere. |
