낙동강 상류유역의 오염원현황과 수질관리 방안에 대한 연구 : 내성천, 영강 유역의 수질관리에 대하여 Management of water quality and pollutant loading in Nakdong upper basin: Naeseong-cheon, Yeong kang basin원문보기
본 연구에서는 낙동강 상류유역의 수질오염 발생이 하류의 미치는 영향이 클 것으로 판단되고, 생활계, 축산계 등의 오염원 증가로 인한 오염부하량이 증가할 것으로 판단되는 상류유역의 내성천, 영강유역을 대상으로 수질개선 방향을 연구하였다. 그리고 유입지류 지천을 중심으로 오염원현황과 수질을 조사하여 계절별 수질변화의 경향을 파악하고, 오염부하량을 산정하여 내성천, 영강 내 수질 오염을 개선하기 위하여 수질 I급수를 기준으로 하여 유역의 오염원 감소...

In this study, the impact of water pollution in the upstream basin of the Nakdong River is expected to be large. Water quality improvement methods were studied for the Naeseong-Cheon and Yeong kang basins in the upstream basin, where the pollutant load is expected to increase due to population and livestock. In addition, the trends of seasonal changes in water quality are investigated by investigating the status of pollutant sources and the quality of water, and the amount of pollutant load is estimated. This study is to analyze the main water quality of Nakdong River caused by water pollution reduction of Naeseong-Cheon and Yeong kang, suggesting the most effective water quality improvement method and presenting it as basic data for future Nakdong River water conservation direction. The major findings are summarized as follows: First, the concentrations of organic compounds BOD, COD, and TOC were high in spring and summer. Nutrients T-N showed high concentration during the dry season, and T-P showed high concentration after summer. Second, the runoff ratios of BOD, T-N, and T-P were high in the Ⅲ and Ⅳ drainage areas where Mungyeong occupied a large share. Ⅲ and Ⅳ drainage areas were found to have more rainfall than other drainage areas. Therefore, it is believed that rainfall affects runoff rate. Third, seasonal BOD, T-N, and T-P runoff rates were the highest in summer. The runoff rate seems to be higher in summer with more rainfall than during dry season. Lastly, the method of improving the water quality of the mainstream of the Nakdong River is the most important for the livestock wastewater, which is the non-point source. As a management method, it would be most effective to strengthen the concentration of discharged water quality in livestock wastewater treatment plants or to reduce livestock wastewater discharge by establishing or expanding livestock wastewater discharge facilities. In the case of BOD, non-point source management is needed to be preferred over basin III, T-N basin I, and T-P basin I.
