Abstract

In this study, divided into small category groups for the residential area it was carried out monitoring for the runoff during precipitation. Based on the results analyzed according to the nonpoint sources Housing leakage characteristics. Analysis of the rainfall runoff and concentration of each type of exclusive detached house with apartments, in the majority of precipitation types runoff concentrations were higher in early. In the case of a difference of two points per runoff rate rainfall it was largely investigation. The average runoff is estimated loadings of BOD $101.1kg/km^2$, SS $232.2kg/km^2$, T-N $18.2kg/km^2$, T-P $2.0kg/km^2$ detached house case, if the apartment was estimated at point BOD $108.82kg/km^2$, SS $329.18kg/km^2$, T-N $57.67kg/km^2$, T-P $4.21kg/km^2$. The average EMCs is BOD BOD 6.6 mg/L, SS 12.8 mg/L, T-N 1.518 mg/L, T-P 0.099 mg/L detached house case, if the apartment was estimated at point BOD 6.3 mg/L, COD 11.2mg/L, SS 14.5 mg/L, T-N 3.1 mg/L, T-P 0.2 mg/L. The initial 30 percentage calculated based on the initial results, the total flow of 30% if the outflow of detached house showed a net percentage difference to T-P 1.04 > T-N 0.97 > BOD 0.90 > SS 0.80. The apartment area showed the percentage difference in the water quality in the order of BOD 1.49 > T-P 1.40 > SS 1.30 > T-N 0.96 per item.

본 연구에서는 주거지역에 대해 세분류 형태로 구분하여 각각에 대해 강우 시 유출수에 대한 모니터링을 실시하고, 그 결과를 바탕으로 주거 형태에 따른 비점오염원의 유출 특성을 분석해 보았다. 단독주거지역 및 아파트지역의 강우사상별 유출형태 및 농도 변화 형태를 분석한 결과 대다수의 강우사상에서 초기유출수의 농도가 높게 나타나는 형태를 나타내었으나 두 지점의 경우 강우량별 유출율의 차이가 크게 조사되었다. 평균 유출부하량은 단독주거지역의 경우 BOD $101.0kg/km^2$, SS $232.2kg/km^2$, T-N $18.2kg/km^2$, T-P $2.0kg/km^2$이며, 아파트지역의 평균 유출부하량은 BOD $108.82kg/km^2$, SS $329.18kg/km^2$, T-N $57.67kg/km^2$, T-P $4.21kg/km^2$으로 산정 되었다. 평균 EMCs는 단독주거지역에 대해 산정된 평균 EMCs의 경우 BOD 6.6 mg/L, SS 12.8 mg/L, T-N 1.518 mg/L, T-P 0.099 mg/L로 조사되었다. 아파트 지점 평균 EMCs의 경우 BOD 6.3 mg/L, COD 11.2mg/L, SS 14.5 mg/L, T-N 3.1 mg/L, T-P 0.2 mg/L로 조사되었다. 주거 형태에 따른 초기세척비율을 산정한 결과, 단독주거지역의 경우 총유출량 기준 초기 30%의 유출 시, $MFF_n$ 값이 T-P 1.04 > T-N 0.97 > BOD 0.90 > SS 0.80의 순으로 비율차이를 나타내었다. 아파트지역 n=30에서 수질항목별 $MFF_n$ 값의 경우, BOD 1.49 > T-P 1.40 > SS 1.30 > T-N 0.96의 순으로 비율차이를 나타내었다.
