Zusammenfassung: | Disclosed is a method for purifying soil contaminated with fluorine using soil washing, which is to continuously purify fluorine-contaminated soil and capable of increasing purification efficiency. The method comprises the following steps: crushing surfaces of contaminated soil containing fluorite mineral by using the difference in hardness; separating the surface-crushed contaminated soil by the particle size into underflow soil and overflow soil; dewatering underflow soil; and discharging the dehydrated underflow soil as purified soil.
연속적으로 불소 오염토양을 정화하고, 정화효율이 높일 수 있는 토양세척을 이용한 불소 오염토양의 정화방법을 제시한다. 그 방법은 형석광물을 함유하는 오염토양을 경도 차이를 이용하여 표면을 파쇄하고, 표면이 파쇄된 오염토양을 입도분리하여 언더플로우 토양 및 오버플로우 토양으로 구분하며, 언더플로우 토양을 탈수하고, 탈수된 언더플로우 토양을 정화토로 배출한다. |
