제올라이트와 슬래그계 물질을 이용한 암모늄, 카드뮴, 인산염의 동시제거능 평가

Abstract

The reactive vertical drain could be applied to man-made island constructed by dredged materials and waste landfill. However, these materials could be considered as main reason of multiple contamination such as ammonium, cadmium and phosphate. Therefore, the reactive vertical drain containing various materials is necessary to remediate many kinds of contamination mentioned above simultaneously. In this study, a series of batch test which consists of two process is performed. Zeolite, basic oxygen furnace slag and blast furnace slag are used as reactive materials. Ammonium, cadmium and phosphate are targeted for removal. As a result, zeolite-basic oxygen furnace slag or blast furnace slag sequence batch test shows the best efficiency for multiple contamination removal.
