초록
피혁 제조 공정별 발생 폐수중 T-N 농도를 증가시키는 오염원이 가장 많이 배출되는 공정중 하나인 탈회공정에 적용 가능한 Non-phosgene화합물을 이용하여 Carbonate계 비질소계 탈회제의 합성 및 적용공정 연구를 통하여 배출 배액에서의 T-N, BOD, COD, SS의 측정결과 탈회후 혁에서의 Ca함량, Cr함량, TS를 측정하여 탈회효율 및 크롬 탄닝혁의 물리적 특성에 미치는 영향과 배출 배액에서의 T-N, BOD, COD, SS의 농도감소효과를 확인하여 친환경 피혁제조공정 확립을 위한 기초 연구를 진행하였다.
A study was made on the synthesis of a carbonate base nitrogen-free deliming agent using a non-phosgene compound applicable to the deliming process, which is one of the biggest sources of pollutant increasing the T-N concentration in the effluent from the leather making processes. And also studied on the possibility of using the agent in the deliming process. Through measurement of T-N, BOD, COD and SS in the effluent after the agent is used, contents of Ca and Cr and TS in the leather after the deliming process were measured, by which deliming efficiency, influences to the physical properties of the chromium tanned leather and reducing effects of T-N, BOD, COD and SS concentrations in the effluent could be confirmed. Thus an eco-friendly study has been conducted.
