수질정화장치 적용에 따른 퇴적물 특성 및 오염물질 상관관계 분석 = Characteristic of Sediment and Correlation Analysis of Pollutant Material with Application of Water Purification Equipment in Lake

다국어 초록 (Multilingual Abstract)

Since the stagnant reservoir water have lots of nutrients to be deposited and a small amount of water per unit area, the releasing nutrient from the sediments has a great influence on the primary production and water quality changes in the aquatic system. Thus, to manage the water quality of the reservoir, there is an increasing demand for the removal of polluted sediment accumulated on the bottom. The purpose of this study is to analyze the physical characteristics and fate of sediment nutrients before and after of the application with the water quality improvement system by selecting most reasonable points to set up and maintain easily applied to the reservoir water quality improvement. For those purpose, since a treatment system using micro-bubble and microbial media was installed, the characteristics of sediments around before and after application of the system and the efficiency of the treatment system had been evaluated. As a result, it was confirmed the soil be classified into silty loam before the installation of the water-treatment system is changed to after the installation be classified into sandy loam. It`s mean nutrient separation from sediment more easily.
