Abstract

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 calculating EMC according to the outflow amount by rainfall event, the 1st rainfall showed EMCs ranges of BOD, CODMn, SS, T-N, and T-P of 1.32~48.76, 3.32~43.75, 2.89~199.43, 2.76~8.93, 0.08~068, and the 2nd rainfall was 0.5~2.9, 2.71~7.13, 2.82~174.94, 1.33~4.03, 0.01~1.28 mg/L, respectively. As a result of calculating the ratio of cumulative outflow and cumulative pollution load, most of the pollution load was less than the rainfall outflow, but over time, the initial washing phenomenon occurred as the ratio of cumulative rainfall outflow and cumulative pollution load increased to more than 1.

본 연구는 강우시 산업단지에서 발생하는 비점오염원 유출 특성을 평가하여 비점오염원 부하량 및 원단위 산정을 위한 기초자료로 활용하기 위하여 C 산업단지에 대하여 강우유출수 수질모니터링을 수행하였다. 강우 사상별 유출량에 따른 EMC 산정 결과, 1차 강우시 BOD, CODMn, SS, T-N, T-P의 EMCs 범위는 각각 1.32~48.76, 3.32~43.75, 2.89~199.43, 2.76~8.93, 0.08~068 mg/L로 나타났으며, 2차 강우시는 각각 0.5~2.9, 2.71~7.13, 2.82~174.94, 1.33~4.03, 0.01~1.28 mg/L로 나타났다. 누적 유출량과 누적 오염부하량 비율 산정 결과, 강우 초기 유출량이 적은 시간에는 대부분 오염부하량이 강우 유출량보다 적지만 시간이 지남에 따라 강우 누적 유출량과 누적 오염부하량의 비가 1보다 커지면서 초기세척 현상이 일어났다.
