초록
본 연구에서는 염료 폐수를 대상으로 영가철을 이용하여 8종류의 염료제거 특성연구를 수행하였다. 영가철에 의한 환원반응은 염료가 성공적으로 제거됨을 확인하였고, 염료 제거 반응속도는 pH에 매우의존적이며 낮은 pH에서 반응속도 및 염료 제거율이 증가되었다. 염료 제거를 한 이후의 산화된 철을이용하여 인산염의 흡착 제거를 증명하였다. 결과로 영가철의 이용가치는 폐수처리 뿐 아니라 폐기물관리의 점에서 환경 친화적인 폐기물 처리에 잠재적으로 많은 영향을 줄 수 있음을 확인 하였다
Abstract
This study was performed to remove the dye characteristics of eight kinds of dye wastewaterusing zero-valent iron. We demonstrate the dye is removed successfully by the oxidation-reductionreaction with the zero-valent iron. The resulting of dye removal reaction is highly dependent onpH and was demonstrated to be increased at lower pH. The adsorption characteristic of waste ironoxide was proposed the method of phosphate recovery from municipal wastewater by using ferrousiron waste after generated from the dye wastewater. As a result it was confirmed that a numberof effects that could potentially environmentally friendly waste disposal in terms of wastemanagement and wastewater.
