Abstract
비점오염저감시설에 대한 연구는 활발히 진행되고 있으나, 도로에 자연형 비점오염저감시설 설치시 비점오염저감효율에 대한 연구는 없는 실정이다. 본 연구에서는 도로에 설치된 여러 종류의 인공습지에 대한 비점오염 저감효율을 모니터링과 유량가중평균농도법을 이용하여 분석하였다. 분석결과, 인공습지는 일반적인 오염물질인 TSS, COD, BOD, TN, TP에 대한 저감효율은 비교적 우수한 것으로 나타났으며 중금속인 Cr, Zn, Pb의 제거효율은 낮거나 거의 없는 것으로 나타났다. Studies of non-point pollutant treatment facilities have widely been conducted for a decade, but natural non-point pollutant treatment facilities implemented on roads have not been carried out for the removal efficiency of non-point pollution sources. This study analyzed the removal efficiency of non-point pollution sources from constructed wetlands using monitoring and event mean concentration method. As a result of this study, removal efficiency of general non-point pollution sources as TSS, COD, BOD is relatively good, but removal efficiency of TN, TP, Cr, Zn, Pb is very small or nothing.
