허효진 (부경대학교 지구환경과학과) , 이민희 (부경대학교 지구환경과학과)
Batch experiments were performed to determine the feasibility of the surfactant-enhanced soil washing process at various washing conditions for the Kuwait soil seriously contaminated with the crude oil. The soil was sampled at a dried oil pond in Kuwait and its average TPH concentration was 223,754 ...

우리나라의 1인당 석유소비량은 순위는? | , 2006). 특히 우리나라는 인구 1인당 석유소비량 세계 5위를 차지할 정도로 석유 의존도가 매우 높고,산유국으로부터 원유를 수입하여 정제과정을 거치는 정유산업이 발전하여 원유를 운반, 저장, 정제하는 과정에서 누출사고나 관리 소홀에 의해 오염토양이 생성될 수 있는 가능성이 매우 높다(BP, 2015). 우리나라의 경우 부산시 문현동 군부대를 시작으로 2000년대 초반부터 유류로 오염된 부지의 정화가 시작되었으나, 아직도 조사조차 이루어지지 않은 유류 오염부지가 많이 존재하고 있다(MOE, 2009; MOE, 2012). | |
동일한 방법으로 정화 작업을 해도 지역에 따라 정화효율이 다르게 나타나는 이유는? | 지하에 유출된 유류는 지하의 불균질성 때문 만 아니라, 종류별로 다양한 물리·화학적 반응특성을 나타내므로 부지 내 거동과 분포를 예측하기 어려워 같은 정화기술이 적용되더라도 지역에 따라 정화효율이 매우 다양하게 나타날 수 있다(Fetter, 2008). 특히 유류오염과 관련된 우리나라 오염부지는 대부분 군부대 유류저장소, 주유소, 산업단지의 유류 저장 탱크 누출과 관련되어 존재하고, 오염원은 가솔린 성분인 BTEX,디젤, 벙커유 등으로 분류되며, 정화방법에 대한 연구도 주로 이러한 유종을 제거하는데 집중되어왔다(MOE, 2010; KEITI, 2015). | |
유류 오염부지의 주요 오염원으로 주목되는 것은? | 지하에 유출된 유류는 지하의 불균질성 때문 만 아니라, 종류별로 다양한 물리·화학적 반응특성을 나타내므로 부지 내 거동과 분포를 예측하기 어려워 같은 정화기술이 적용되더라도 지역에 따라 정화효율이 매우 다양하게 나타날 수 있다(Fetter, 2008). 특히 유류오염과 관련된 우리나라 오염부지는 대부분 군부대 유류저장소, 주유소, 산업단지의 유류 저장 탱크 누출과 관련되어 존재하고, 오염원은 가솔린 성분인 BTEX,디젤, 벙커유 등으로 분류되며, 정화방법에 대한 연구도 주로 이러한 유종을 제거하는데 집중되어왔다(MOE, 2010; KEITI, 2015). 지난 5년간 국내 유류오염 부지에 적용되었던 토양 정화방법을 분석한 결과토양경작법(Soil land farming)이 전체의 62%를 차지하는 것으로 나타났다(Table 1). |
