dc.description.abstractNDMA(N-Nitrosodimethylamine)는 극저농도(10ng/L)에서도 암을 일으킬 수 있는 물질로 알려져 있지만, 기존의 NDMA 제거율 평가 연구는 고농도의 NDMA를 대상으로 한 것이 대부분이었다. 따라서 극저농도의 NDMA 제거효율 평가가 필요하며 그 기초연구로써 호기성/혐기성 조건에서의 분말활성탄, GS(Granular Sludge), MF(Microfiltration), UF(Ultrafiltration)를 이용한 제거효율과 Silica gel(MCM-41, Diatomite, Spherical silica gel)을 이용한 제거효율을 평가하였다. 그 결과 혐기성 조건에서 GS, PAC를 접촉한 후 UF membrane을 이용한 고액분리가 65%의 제거율로 가장 높았으며, Silica gel(MCM-41)이 6%의 제거율로 가장 낮았다. 본 연구는 극저농도의 NDMA 제거의 기초 연구로서 향후 관련 연구의 기초자료로써 활용을 기대한다.-
dc.description.abstractNDMA(N-Nitrosodimethylamine) has been considered as a carcinogenic pollutant even at extremely low-concentration (10ng/L). However, previous researches on NDMA have focused on mainly high concentration due to a difficulty of analysis. In this study, removal efficiencies were evaluated for individual or combined methods with PAC(Powder Activated Carbon), GS(Granular Sludge), MF(Microfiltration), UF(Ultrafiltration) and Silica gel(MCM-41, Diatomite, Spherical silica gel) at both aerobic and anaerobic conditions. Combined method of GS, PAC and UF membrane at anaerobic condition showed the highest removal efficiency of 65% while Silica gel showed the lowest removal efficiency of 6%. The outcomes of this study could be used further study of extremely low-concentration NDMA removal.-
