성층화된 다목적 댐호의 수질관리 = Water Quality Management of Stratified Reservoir

다국어 초록 (Multilingual Abstract)

The purpose of this study is to review water quality management technology of reservoir, and to suggest the best technology for the improvement of water quality of stratified reservoir.
Until present many domestic, industrial, and livestock wastewater treatment facilities have been constructed and operated to improve the water quality of stream, river, and reservoir together with the implementation of many land use based regulation of watershed. But most multipurpose reservoir in Korea have been heavily eutrophicated, and they do not keep Korean Water Quality Standards.
In case of Daechong Reservoir, the stratification of temperature and DO is predominant compared to other water quality constituents such as COD, T-N, and T-P. There are various technologies for the improvement of water quality in stratified lake or reservoir. The selective outflow and aeration of water of polluted hypolimnion could improve the water quality temporarily, but it can not solve the water quality problem fundamentally. Therefore, should be implemented the point sources control by wastewater facilities and nonpoint sources management such as land use based regulation, and environmentally sound and sustainable industrial location.
