Abstract

The purpose of this study was to develop water-purification vegetation mats consisting of the eco-friendly materials and to validate their water purification capabilities with the objective of reducing nonpoint pollution into streams. The developed vegetation mats are made of coconut fiber shell and filling consisted of zeolite, diatomaceous earth or a mixture of calcinated foam media. The bench scale assessment of the water purification capability of the three filling materials showed that the removal efficiencies of suspended solid (SS), total nitrogen (T-N) and total phosphorus (T-P) were higher in the foam media than in zeolite or diatomaceous earth. From the results of the field experiment, the removal efficiencies of the vegetation mats filled with the foam media were 60.1% in SS, 32.2% in T-N and 20.2% in T-P. Therefore the vegetation mats filled with the foam media calcinated from zeolite and diatomaceous earth should have higher efficiencies in controlling the nonpoint source pollutions in streams.

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.
