Soil remediation facility and soil remediation method using the same

Abstract

A soil remediation facility includes a first screen apparatus including a vibratory screen, a drum mixer apparatus mixing the contaminated soil with a diluent, a saturated steam and hot water, a scrubbing apparatus including a mixing container and an impeller, a second screen apparatus including a vibratory screen. The facility further includes a floatation apparatus which adds a chemical agent for generating bubbles to the soil mixture, injects an air into the soil mixture to desorb contaminants from the soil mixture, and separates the desorbed contaminants by causing the desorbed contaminants to float. The facility further includes a hydro-cyclone apparatus which swirls substances contained in the soil mixture to sort the substances depending on a particle size and a desilter which swirls substances in the soil mixture at a higher angular velocity than an angular velocity in the hydro-cyclone apparatus to sort the substances.
