본 연구는 강우시 산업단지에서 발생하는 비점오염원 유출 특성을 평가하여 비점오염원 부하량 및 원단위 산정을 위한 기초자료로 활용하기 위하여 C 산업단지에 대하여 강우유출수 수질모니터링을 수행하였다. IETD 분석결과, 강우지속시간 약 21시간, 강우량 26.44mm인 27시간일 때 비점오염원 모의를 위한 대표 강우 사상으로 선정되었으며, 유량 및 수질조사 모니터링 결과, 1차 강우시 강수량 12.2mm, 강우지속기간 12hr, 선행 건기일 수 3일이었으며, 2차 강우시 강수량 22.1mm, 강우지속시간 12hr, 선행 건기일 수는 7일이었다.
In this study, rainfall water outlet water quality monitoring was performed on the C industrial complex to evaluate the characteristics of non-point pollutant runoff from the industrial complex during rainfall and to use it as basic data for calculating the load and unit of non-point pollutant. As a result of the IETD analysis, it was selected as a representative rainfall event for simulating non-point pollutants when the rainfall duration was about 21 hours and the rainfall was 26.44mm. Also as a result of monitoring the flow and water quality survey, the first rainfall was 12.2 mm, the rainfall duration was 12 hr, the number of preceding dry days was 3 days, the second rainfall was 22.1 mm, the rainfall duration was 12 hr, and the number of preceding dry days was 7 days.
