Determination of Pollutant EMCs and Loadings of Runoff in Paved Areas
Kyung-Ik Gil, Seung-Kyung Wee, Moo-Jong Park
Abstract
The paved area like a road or bridge where having high impermeable rates were accumulated various non-point sources(NPS) by passing vehicles during dry season periods. They are flowed in the river continuous when it rains and could negative impact on environment. Therefore, this study monitoring NPS for two years and determinating for each pollutant EMCs and mass loading. The result shows that the EMC ranges are 11.60$sim$230.90 mg/L for TSS, 4.58$sim$31.90 mg/L for BOD, 1.86$sim$9.20 mg/L for TN and 0.14$sim$1.55 mg/L for TP. Also, the ranges of washed-off mass loading are determined to 0.78$sim$18.01 kg/day for TSS, 0.47$sim$1.17 kg/day for BOD, 0.00$sim$0.01 kg/day for Pb and 0.01$sim$0.06 kg/day for Zn.
Key Words: Event mean concentration (EMC); mass loading; Nonpoint source; Runoff
요지
도로나 교량과 같은 불투수율이 높은 포장지역의 경우 차량의 통행으로 건기기간 동안 축적되어 있던 다양한 비점오염원이 강우 지속시간 동안 인근 하천에 유입되어 심각한 영향을 미치고 있다. 따라서 본 연구는 2년 동안 모니터링을 실시하여 각 오염물질별 유량가중평균농도 및 오염 부하량을 산정하였다. 모니터링 결과 TSS EMC는 11.60$sim$230.90 mg/L의 범위, BOD EMC는 4.58$sim$31.90 mg/L의 범위, TN과 TP의 EMC는 각각 1.86$sim$9.20 mg/L, 0.14$sim$1.55 mg/L의 범위로 산정되었다. 또한 오염 부하량은 TSS는 0.78$sim$18.01 kg/day의 범위, BOD는 0.47$sim$1.17 kg/day의 범위로 산정되었고, Pb은 0.00$sim$0.01 kg/day의 범위, Zn은 0.01$sim$0.06 kg/day의 범위로 산정되었다.
