Over the past 30 years, there has been an effort to run the facility which manages the domestic, industrial, and animal related sewages in Korea. Despite the effort, there has not been much improvement in the water quality in the lakes and marshes as expected. The limitation of the current water system is that, an inflow of the rainfall and other contamination elements are not being managed properly and so, there are a lot of efforts being made to effectively contain the contamination. The modeling locations are the Gwang-ju stream in Young-san river. These River of water quality was exceeded between level II~III, and the cause for that were determined as the non-point pollution material. The Ministry of Environment has set the Gwang-ju as supervised area to plan, establish, and to preform the 5.0 mg/L BOD concentration. We have carried out this research to improve the water quality at the main course of the Young-san river by proper calculation of capacity for the efficient management with non-point pollution source processing facility installation G stream in drainage area of Gwang-ju stream.

우리나라는 지난 30년간 점오염원 저감시설 확충 및 기술개발을 통하여 오염원을 관리해 왔으나, 상대적으로 비점오염원에 대한 관리는 미흡한 실정이다. 이러한 비점오염원은 대부분 강우초기 유출된다. 연구대상지인 광주천과 영산강의 수질은 BOD 기준 II~III등급을 나타내고 있으며, 주원인은 비점오염원에 의한 영향으로 나타났다. 환경부는 광주광역시에 BOD 5 mg/L 목표달성을 위해 오염 부하량 삭감 방안을 수집, 이행토록 하고 있다. 본 연구에서는 광주천 지류인 G천 유역의 비점오염원 처리시설 설치 시 효율적 처리를 위한 적정용량 산정을 통하여 영산강 본류 구간의 수질개선 목표달성에 이바지 하고자 연구를 수행하였다.
