Abstract

Many researchers have studied that many processes to effectively remove heavy metals in water/wastewater. Especially, among many processes, physical and chemical processes are relatively simple and obtain high treatment efficiency for removal heavy metals compared with biological treatment. Recently, interests in physical and chemical methods are sharply increasing again because of dangerousness for radioactive element. In this study, various physical and chemical processes such as chemical precipitation, ion-exchange, electrodialysis, and membrane separation are introduced.

연구자들은 용수 및 폐수 내에 함유되어 있는 중금속을 효과적으로 제거하기 위한 많은 공정을 연구하고 있다. 많은 공정들 중에서 특히, 물리, 화학적 공정은 생물학적 공정과 비교해볼 때 대체로 간단하고 높은 중금속 제거효율을 얻을 수 있다. 최근에는 방사능원소에 대한 위험성 때문에 물리, 화학적 방법들에 대한 관심이 다시 급격하게 증가하고 있다. 이 연구에서는 화학적 침전, 이온 교환, 전기투석, 그리고 막 분리 등과 같은 다양한 물리, 화학적 공정들을 소개하고자 한다.
