Zusammenfassung:	Disclosed are a dredged soil purifying apparatus for purifying dredged soil contaminated by polluted substances and a purifying method thereof. The dredged soil purifying apparatus comprises: a heat treatment unit for heating the dredged soil and volatilizing and removing polluted substances from the heated soil; a pre-processing unit for physically processing the polluted substances, attached on the surface of the dredged soil; a separating unit for separating the dredged soil into coarse grained soil and fine-grained soil according to the size of the particles; and erupting unit for chemically erupting the polluted substances, remaining in the fine-grained soil, separated from the separating unit. 오염물질에 의해 오염된 준설토를 정화시키는 준설토 정화장치 및 정화방법이 개시된다. 상기 준설토 정화장치는, 준설토에 열을 가하여 오염물질을 휘발시켜 제거하는 열처리수단과, 상기 준설토의 표면에 부착되어 있는 오염물질을 물리적으로 처리하는 전처리수단과, 상기 준설토를 입자크기에 따라 크기가 큰 조립토와 크기가 작은 세립토로 분리하는 선별수단과, 상기 선별수단에서 분리된 세립토에 잔존하는 오염물질을 화학적으로 처리하는 용출수단을 포함할 수 있다.
