초록

미국 환경 보호청(Environmental Protection Agency, EPA)의 생물저류 설계기준에 근거한 비점오염원 처리시설의 제거효율 및 성능을 분석하고자 기본 모형 실험장치(basic column reactor, BCR)와 파일럿 규모의 식생 실험 장치를 대상으로 각각 수행하였다. BCR을 이용하여 초기강우 유출수의 유입속도(유량), 식재 층의 조성 및 구성 비율, 등 처리시설의 설계에 필요한 적정인자 값을 도출하였으며 이를 식생 실험 장치에 적용하여 비점오염원의 제거 효율을 분석하였다. 비점오염원으로는 합성된 강우 (synthetic rainfall)와 실제 현장(도로변과 주차장)에서 채수한 초기강우 유출수(first rainfall runoff)를 각각 사용하였다. 부유물질(Suspended Solid, SS), 생물학적 산소 요구량(Biochemical oxygen demand, BOD), 화학적 산소요구량(Chemical Oxygen Demand, COD), 총질소(Total Nitrogen, T-N), 총인(Total Phosphorus, T-P) 분석항목 모두 80% 이상을 상회하는 제거효율을 보이고 있음을 확인하였다.

This study was purposed and performed to evaluate removal efficiency of non-point source pollution in the process and system based on bio-retention design criteria regulated by EPA. Basic Column Reactors (BCR) were prepared for optimal determinations of inflow rate of first rainfall runoff and composition and ratio of soil layers. Removal efficiencies of non-point source pollution from synthetic runoff and real first rainfall runoff, directly sampled from motor way and parking lot, were analyzed, respectively. Removal efficiency of SS, BOD, COD, T-N, and T-P were all shown to be more than 80%.
