This research was carried out to investigate chemical pretreatment using lime and limestone in treating abandoned mine drainage with anaerobic treatment. If treating lime with abandoned mine drainage, after 2day, pH was increased to 5.6, and $SO_4^{2-}$, Fe, Al, Pb and Mn were removed 5.7%, 63%, 57, 45% and 28%, respectively. It was estimated that lime dosage was 2,000mg/L for increasing to pH 7. If treating limestone with abandoned mine drainage, after 2day, pH was increased to 3.67, and $SO_4^{2-}$, Fe, Al, Pb and Mn were removed 4.7%, 26%, 22% 18% and 8%, respectively. It could be showed that limestone did slowly react with temperature increasing. If treating anaerobic limestone packing column with abandoned mine drainage, for experimental period, average pH was 4.51, and average $SO_4^{2-}$, Fe, Al, Pb and Mn were removed 4.5%, 15.3%, 20.1%, 23.7% and 5.87%, respectively. So, it would not be suitable for abandoned mine drainage. But if utilizing limestone as pretreatment process for treating abandoned mine drainage with SRB, because it did initally neutralize abandoned mine drainage, it could forward to stabilize system.
