Abstract

Estimation of annual sludge production on the top of mushroom compost in SAPS in three abandonedmines (Donghae-7th adit, Hwangji-Yuchang and Honam mines) was investigated. The pH of AMD ranged5.62~6.97 and dissolved Fe concentrations decreased in accordance with the direction of treatment process. Sludgeproduction was estimated by three methods: direct measurement of sludge thickness, calculation from Fe decrease,and Imhoff cone experiment. Annual sludge productions of Donghae-7th adit, Hwangji-Yuchang and Honam mineestimated by sludge thickness measurement were 48.6~54.8, 4.4~33.4, 18.9~29.3 m3/year, respectively. The resultswere higher than the values calculated from decrease in Fe content (6.8~8.6, 26.8~33.8, and 8.7~19.5 m3/year,respectively). The results of Imhoff cone experiment were 63.5~254.0, 33.0~165.2, 8.7~19.5 m3/year, respectively.Such disagreement between three methods is likely due to sludge consolidation on site. Therefore, continuousmonitoring and experiments are required, and setup of empirical modified equation from results of laboratoryexperiment is needed.

국내 3개 폐광산(동해 7갱, 황지유창, 호남광업소)의 SAPS조 퇴비층 상부에서 발생하는 연간 슬러지량을 계산하였다. 각 광산배수의 pH는 5.62~6.97로 약산성에서 중성을 나타내었으며, 용존 Fe는 산화침전조와SAPS를 지나며 대부분의 Fe가 제거되었다. 슬러지 발생량은 1) 슬러지 두께의 직접 측정, 2) Fe 감소량으로부터계산, 3) 실험실내 Imhoff cone을 이용한 실험값의 세 방법으로 추정하였다. 각 SAPS 내 슬러지 두께를 직접측정하여 연간 발생량을 산출한 결과 각각 48.6~54.8, 4.4~33.4, 18.9~29.3 m3/year로 확인되었다. 이는 Fe 저감량으로부터 산출한 연간 발생량(각각 6.3~8.6, 26.8~33.8, 8.7~19.5 m3/year)보다 전반적으로 높은 값으로 나타났다.Imhoff cone 실험 결과, 연간 슬러지 발생량은 각각 63.5~254.0, 33.0~165.2, 136.4~165.7 m3/year로 나타났다.세 방법 간의 불일치는 현장 슬러지가 시간이 경과하며 압밀되기 때문인 것으로 판단된다. 향후 지속적인 모니터링과 실험이 요구되며, 실내실험만으로 압밀층이 고려된 슬러지 두께 산출이 가능한 경험적 보정식 도출이 필요하다.
