An neutralization-precipitation process for treating an acid mine drainage (AMD) was set up witha process simulator. Flow rate of AMD was 100 m3/d. 150 kg/d of lime was used for neutralizing the AMD.1 kg/d of polymer was used for coagulating the suspended solids. Solid removal rates of 90% and 95% wereassumed for a clarifier and a thicker, respectively. The AMD with a pH of 2.69 contained Fe, Al, Cu and Zn.It was simulated that iron hydroxide could be produced at 32.2 t/yr, aluminum hydroxide at 6.4 t/yr and copperhydroxide at 3.3 t/yr. Simulation result showed that aeration process consumed the largest electricity than otherprocess. It was evaluated that process simulation could play roles in making a better decision for AMD treatmentoptions.
공정분석 시뮬레이터(simulator)를 이용하여 산성광산배수 중화침전공정을 구축하고 시뮬레이션 하였다. 운전 조건으로 광산배수 처리 유량은 100 m3/d 이었고 소석회 및 폴리머 응집제 사용량은 각각 150 kg/d및 1 kg/d 였다. 침전조 및 농축조에서 고형분 제거율을 각각 90%와 95%로 가정하였다. 수질은 pH가 2.69인산성수로서 Fe, Al, Cu, Zn 으로 오염된 광산배수였다. 시뮬레이션 결과 철 수산화물은 30.2 t/yr, 알루미늄 수산화물은 6.4 t/yr 그리고 구리 수산화물은 3.3 t/yr 발생하는 것으로 예상되었다. 폭기 공정에 가장 많은 전력이소요되었다. 시뮬레이션 기법은 산성광산배수 처리 계획 수립시 의사결정에 유용한 도구로 생각되었다.
