초록
본 연구는 달성광산 광산배수의 자연정화처리시스템을 평가하기 위하여 수행되었다. 이를 위하여 현장조사와 이화학 · 광물학적 분석, 오염부하량 산정, 상관성 및 특성-특성도 분석 등의 다양한 수리지구화학적 기법을 이용하여 처리 전후의 광산배수 수질 특성을 비교하였다. 광산 배수 내 존재하던 용존 철은 처리시스템을 통해 산화물 형태로 제거되었으며, 구리는 수착반응에 의해 제거되었지만 아연은 40% 정도가 제거되어지지 않고 인근 하천으로 방류되는 것을 확인하였다. 처리수와 하천수의 혼합지점에서는 산화, 흡착, 침전, 그리고 공침 등의 다양한 화학반응으로 인하여 대부분의 오염물질들이 저감되는 것으로 나타났고 하류수계로 갈수록 오염물질의 농도와 오염부하량이 감소하는 것을 확인하였다
Abstract
This study was conducted to assess the passive treatment process of the acid mine drainage originated from Dalseong mine. The properties of mine drainage between prior to and after the treatment process were compared using a variety of hydrogeochemical methods including field investigation, chemical and instrumental analyses, mineralogical observation, calculation of pollutant loading, correlation analysis, and property-property evaluation. The dissolved iron in the mine drainage was oxidized into the iron (oxyhydro)oxides and removed by the process. In addition, most of Cu was equestrated by the process, but 40% of Zn was not removed and discharged into the nearby stream. At a confluence with stream water, most of contaminants were removed by various chemical reactions such as oxidation, adsorption, precipitation, and coprecipitation, and finally the concentration and loading of pollutants significantly decreased with increase in distance from the confluence.
