Abstract

After the heavy rain in July 2006, a large amount of mine water leading to yellowboy in the river adjacent to the adit flew out from the ventilation adit constructed at the Yeonhwa mine in Taeback area. Since the pH of mine water has shown the neutral condition, the heterogeneous oxidation system of iron could be considered to be a appropriate treatment method for it. In this study, feasibility of heterogeneous oxidation system to treat mine water was evaluated by performing laboratory scale experiments and pilot scale experiments. The iron removal ratio was higher than 95%. The iron concentration and the amount of suspended solids were lower than the standards of effluent water (2 mg/L and 25 mg/L, respectively). Estimated treatment capacity of the system is 530 g/m2/day which is about 26.5 times of that of passive treatment systems composed of oxidation ponds and aerobic wetlands.

연화광산 태백지구의 통기갱에서 2006년 7월 폭우 이후 다량의 광산배수가 유출되어 주변 하천에 황화현상이 나타났다. 연화광산 통기갱에서 유출된 광산배수의 특성을 분석한 결과, 일반적인 광산배수의 특성(낮은 pH와 높은 철농도)과 달리 pH가 중성이고 철농도가 평균 24 mg/L 수준이며, 철을 제외한 다른 중금속 함량이 낮았다. 이에 연화광산 통기갱 갱내수의 처리기술로 불균질 산화 시스템의 적용가능성을 실내실험과 현장실험을 통해 연구하였다. 실험 결과, 통기갱 갱내수에 대해 불균질 산화 시스템의 철제거율이 95% 이상으로 처리후의 철농도와 부유물질량은 배출수 수질기준(2 mg/L, 25 mg/L)보다 낮아졌다. 본 연구의 불균질 산화 시스템의 처리용량은 530 g/m2/day로 이는 일반적인 자연정화처리시설 처리용량(20 g/m2/day)의 26.5배에 해당한다.
