초록

본 연구는 도시 산업지역의 넓은 불투수 지역뿐만 아니라 좁은 지역의 도로 교량이 통과되는 하천유역에서 발생되는 비점오염원을 초기우수로부터 저감시킴으로써 하천수질의 오염을 줄일 수 있는 저감장치를 개발하여 실용화하고자 한다. 이를 위해 본 연구의 선행연구에서 취득한 자료를 기반으로 현장 성능시험용 저감장치를 개발하여 생화학적 산소요구량(BOD), 화학적 산소요구량(COD), 총질소(T-N)와 부유물질(SS)의 저감효율에 대한 성능시험을 실시하였다. 성능분석 결과는 시간구간별 시험항목의 분석에서 그 성능이 우수한 것으로 확인되었다. 그 결과는 국립환경 과학원에서 제안한 비점오염 저감시설의 요구 저감효율을 충족시키는 것으로 나타나 실무활용이 가능할 것이다.

This study aims at development and application of a facility that is capable of reducing pollution in water quality by reducing nonpoint source pollutants (NPSP). NPSP originated from the initial rainfall caused not only large catchment of urban area pass a river but also small watershed pass a stream. For this purpose, the performance tests carried out with the field models from the facility based on the preceding study. And the tests induced reduction efficiency of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total nitrogen (T-N) and suspended solid (SS), respectively. The average reduction efficiency obtained by time interval, and the result showed an excellent reduction performance. As a result, the facility satisfied reduction efficiency of NPSP of the proposed standard by the National Institute of Environmental Research, and thus it can be used in practical applications.
