  • Method using artificial freezing technique for sealing and displacement of soil pollutant
    Patent number: 10654082
    Abstract: Disclosed is a method using an environmental-friendly and artificial freezing technique for sealing and displacement of a soil pollutant. The method for displacement of the soil pollutant comprises: performing an artificial freezing technique on an area and depth of a surveyed contaminated site to form a sealed frozen wall along the perimeter of the contaminated site, by using the excellent permeation resistance function of the frozen wall to seal the contaminated site and to prevent the pollutant from spreading further; selecting a freezing temperature of ?10° C. to ?30° C. according to characteristics of the freezing temperature and precipitation rate of the pollutant, by controlling the freezing rate to 1 cm/day to 10 cm/day, and performing freezing displacement of the soil pollutant from outside to inside using a principle of freezing purification, to concentrate the pollutant; and subjecting the remaining high concentration of contaminated soil to chemical treatment.
