영문 초록

This research is to determine the stormwater effects on sewer concentrations by measuring and comparing the flow and pollutant concentrations during dry and rainy periods in the existing BOX type combined sewer pipes. The monitoring was carried out in two sites, which were the Daesachen outfall having PE separation wall in BOX type combined sewer pipes and the Yongunchen outfall not having seperatioin wall. According to the research, the separation wall controls 52% pollutant mass during a storm period(11.5 mm/hr rainfall intensity). Therefore, The seperation wall controlled about 53% nutrient pollutant mass loading a storm period(11.5mm/hr rainfall intensity) in Dasachan outfall. If the seperation wall is installed in Yongunchen, nutrient pollutant mass loading controls 61% of TN, 62% TP respectively. Overflowing pollutant mass loading is 16 fold as BOD, 18 fold as TN and 13 fold as TP higher in Youngunchen outfall than in Daesachen outfall.
