| 초록 | This study focused on the survey for environmental impacts and hazard occurred in the abandoned metallic mines and their countermeasures. Major issues in the inactive metal mines were mine drainage, tailings, waste rock dump, abandoned facilities, in which acid mine drainage was a principal factor to deteriorate the environment around the abandoned mines.Chemical analysis shown that mine drainage was very acidic and were very acidic and were contaminated by toxic elements such as As, Pb, Cd, Mn, Fe, Cu and S etc. In addition, soil near the tailings impoundment was contaminated by heavy metals such as As, Pb, Cd, and cyanide. An column test was carried out to develop the passive treatment system for amelioration of the acid mine drainage with heavy metals. The experimental results revealed that composite mixed with the saw dust and cow manure was evaluated as the best substrate to have good permeability and to have enough food necessary for sulfate reduction bacteria. Small scaled anoxic wetland had been operated to confirm the capabilities of acid mine drainage treatment. The demonstration of the system revealed that the system neutralized acid mine drainage and also eliminated some metals such as Fe, Al, Mn, Cu, Cd, Pb and Zn etc up to by 98% |
