THE METHOD OF MAKING A ARSENIC IMMOBILIZER USING ACID MINE DRAINAGE SLUDGE AND METHOD OF PURIFYING THE CONTAMINATED SOIL USING THE ACID MINE DRAINAGE SLUDGE

摘要

The present invention relates to a method for manufacturing arsenic elution suppressants using an acid mine drainage sludge, comprising: a first step of obtaining an acid mine drainage sludge through a collecting method for high concentrations of sludge by discharging acid mine drainage to a water system using a reactor and a settling tank after performing physiochemical treatment on the acid mine drainage; and a second step of manufacturing arsenic elution suppressants for suppressing elution of arsenic (As) contained in soil by combining the acid mine drainage with cement, and sand at a certain ratio or combining the acid mine drainage, cement, and sand with at least one from an arsenic acid agent and slaked lime.
