오염원 관리방안에 따른 전라북도 섬진강 수계의 수질개선에 관한 연구 = A Study on Water Improvement of Jeollabuk-do Seomjingang Water System according to Pollutant Management Plans

다국어 초록 (Multilingual Abstract)

This country has conducted Total Pollutant Load Management System to manage and improve a water quality of a river, and has tried to prevent environmental pollution. A water quality will be contaminated by the economic growth, so policy and study should be studied and developed to keep in step with the economic growth. This study formed a scenario to improve a water quality by expecting and analyzing a water quality of Jeollabuk-do Seomjingang water system, so calculated a result. Jeollabuk-do Seomjingang water system in 2020 expected on the basis of 2012 is similar to a system in 2012, but rises slightly, and pollution of water quality increases by joining of each branch river. Therefore, contribution ratio was calculated by balancing 58 model input materials, and 3 places were selected and analyzed to calculate a hot degree by pollutant input materials by branch rivers. A result of an analysis showed that the cause is sewage disposal plant, and domestic, livestock, and land point and non-point pollution sources. This study expected and compared a water quality of Jeollabuk-do Seomjingang water system in 2020 according to a solution of hot degree causes, by forming a scenario. As a result, it was analyzed that a water quality is improved at 15.32% of the maximum BOD, 7.17% of T-N, and 62.86% of T-P according to domestic and livestock cut amount by reinforcing discharge water of sewage disposal plant and improving pollutant management plans. It was analyzed that supplementing various cut plans such as establishment of efficient cut plans, plans to decrease pollution loading amount, plans to increase sewage disposal efficiently, pollutant decrease through an expansion of sewage disposal area, and energy recovery from animal dung of Total Pollutant Load Management System, and developing a study on more efficient improvement plans of water quality by considering natural increase and economic development are efficient in an improvement in a water quality.
