유기염소 제거를 위한 공정선택

목차

1. 서 론

유기염소의 이용 : 유기염소는 일반적으로 불활성이며 무해하다고 생각되어 왔기때문에 각종 화학공정의 중간체, 공업용 용제, 드라이 클리닝 용액, 마취제등으로 널사용되어 왔다.
대표적인 유기염소와 그 이용은 아래의 < 표 1 > 과 같다.

2. 유기염소 제거를 위한 공정

① STRIPPING ( 정류 )
② ADSORPTION ON ACTIVATED CARBON ( 활성탄에 의한 흡착 )
③ ADSORPTION ON POLYMERIC RESINS (고분자 수지에 의한 흡착)
④ BIOLOGICAL OXIDATION ( 생물학적 산화 )
