통영시와 양산시의 건기시 합류식 하수관거 월류수(CSOs)에 관한 비교연구 = A Comparative Study on Combined Sewer Overflows(CSOs) for Dry Season in Tongyoung and Yangsan City

다국어 초록 (Multilingual Abstract)

Two analysis sites were set up each for this study in the city of Tongyoung, which has the characteristics of a coastal area, and in the city of Yangsan, which has the characteristics of an inland area, water quantity, and water quality and analysis of initial rainfall pollution level on Combined Sewer Overflows(CSOs) were performed. Based on the findings of these analyses. comparing and predicting the characteristics of effluent considering rainfall intensity using SWMM modeling is the purpose of this study. Following the compilation and analysis of data. the selection of analysis sites for preliminary samples, and the confirmation and examination of the sites for the field study, two sites for the analysis of CSOs were chosen each in the city of Tongyoung, a coastal area, and in the city of Yangsan, an inland area. The analysis of water quantity on CSOs was conducted with Flo-Tote(Ⅱ). For analysis parameters. BOD_(5), COD_(Cr), TSS, T-P, and T-N were analyzed 12 times a day. The results of SWMM modeling based on the amount of rainfall of Tongyoung and Yangsan revealed a little difference between measured value and predicted values, but the difference was modest in terms of volume. However, continuous studies on major coefficients and variables considering the amount of rainfall and local characteristics are required for more exact conclusion.
