Abstract
Passive mine water treatment system was used for the treatment of the mine water, and consistedof SAPS(Successive Alkalinity Producing System), OP(Oxidation/settling Pond) and wetland, etc. This study was carried out for physical and chemical analysis of sludges of Waryong, Donghae (6th adit) and Honam mine to investigate the basic properties of the sludges settled in the passive mine water treatment system. The water content of the sludges collected from SAPS was found to be about 50% to 72% and that of the sludges collected from OP was found to be about 59% to 73%. The particle size of sludges was various. From the XRF analysis, the content of Fe2O3 was over 70% at most sludges. The Cd concentration of sludges from the ICP-OES analysis exceeded the soil contamination standards of the heavy metals.
국내에 분포하고 있는 자연정화시설은 주로 석탄광에서 나오는 갱내수를 처리하기 위해 사용되고있으며 일반적으로 알칼리도 공급 시스템(Successive Alkalinity Producing System, SAPS), 산화·침전조, 소택지 등으로 구성된다. 본 연구에서는 와룡, 동해6갱, 호남광업소의 자연정화시설 반응조에서 침전되는 슬러지의 기본적인 특성을 파악하고자 물리·화학적 분석을 수행하였다. 알칼리도 공급 시스템 슬러지의 함수율은 약 50~72%으로 나타났고, 산화·침전조의 함수율은 59~73%로 나타났다. 입도분석 결과 슬러지의 입도가 다양한 것으로 나타났으며, XRF 분석 결과 대부분 슬러지에서 Fe2O3의 함량이 전체에서 70% 이상을 차지하였다. 슬러지에 대한 ICP-OES 분석 결과 Cd의 농도가 토양오염기준치를 초과하였다
