영문 초록

The characteristics of floc formation of the iron(Fe) ions contained in the acid mine drainage was studied for developing the process treating the acid mine drainage. The iron(Fe) ions were formed into flocs by the acid-base reaction with the added Ca(OH)2 . The molal ratio of iron(Fe) vs Ca(OH)2 was one of major control variables in treatment; pH change, iron(Fe) ions concentration in treated drainage, DO (dissolved oxygen content). In addition, the air gave much effect on the color of the iron(Fe)-Ca(OH)2 flocs and the attachment to magnet. The attaching to the magnet of the flocs formed in the air was much less than the case without air.
