초록

본 연구의 목적은 하천과 호소로 유입되는 비점오염을 저감하기 위해 자연형 하천조성기술 중에서 활용성이 증가되고 있는 식생 매트에 충진재를 적용하여 수질정화기능을 향상하는데 있다. 본 연구에서는 우수한 충진재 선별을 위하여 제올라이트, 규조토 그리고 이들을 혼합하여 소성한 발포여재에 대한 수질정화기능 실내 평가실험과 제방사면조건에서 강우 유출수를 대상으로 한 식생 매트의 수질정화능 검증 현장실험을 진행하였다. 충진재별 수질정화기능은 발포여재가 SS 46.3%, T-N 29.9%, T-P 33.3%로서 다른 충진재보다 수질정화기능이 우수하였다. 식생 매트의 현장 실험에서는 수질정화능은 SS가 60.1%, T-N이 32.2%, T-P가 20.2%으로서 식생 매트의 우수한 오염저감 능력을 확인할 수 있었다.
