Abstract

원재료로서 철 및/또는 철함유 화합물, 시멘트질 물질, 물, 블리딩을 촉진시키는 혼화제 함유물을 사용하고, 원재료에 함유시키는 물의 2.0중량% 이상을 블리딩시키면서 고화시켜서, 흡수율 10% 이상이 되는 세공을 형성한 탈인재 및 이 탈인재를 인함유 수용액과 접촉시키는 탈인방법.
상기 탈인재는 표면에 인성분을 고정시킴으로써, 하수, 하천등에서 유효하게 인농도를 저하시킬 수 있다. 상기 탈인방법에서는 단순히 탈인재를 인함유 수용액에 접촉시키는 것만으로 실시할 수 있는 극히 간편한 방법이며, 특별한 관리도 필요로 하지 않아서 유효하게 인성분을 제거할 수 있다.

Description

탈인재 및 탈인방법 (DEPHOSPHORIZING MATERIAL AND DEPHOSPHORIZING METHOD)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 실시예 1에서 조제된 탈인재(脫璘材)를 사용하여 측정한 탈인재에 호소(湖沼)의 인함유 수용액을 통수(通水)시킨 전후의 인농도를 경시적으로 예시하는 그래프이다.
제2도는 실시예 2에서 조제된 탈인재를 사용하여 측정한 탈인재에 하수를 접촉시킨 전후의 인농도를 경시적으로 예시하는 그래프이다.
제3도는 실시예 3에서 조제된 탈인재를 사용하여 측정한 탈인재에 호소의 인함유 수용액을 통수시킨 전후의 인농도를 경시적으로 예시하는 그래프이다.
