초록

The purpose of this study is to investigate CSOs(combined sewer overflows) control in the combined sewer with/without separation wall. There is the high correlation between sewage velocity and suspended solid(SS) loading in the sewer without it. The SS/BOD ratio was about 3 times in the area with it, while it was about 5 times in the area without it. Therefore, the accumulated deposit within the sewer has influenced high SS loading in the sewer without it. This study showed that the separation wall installed acquired an acceptable efficiency in controlling the accumulated deposit in the combined sewer. According to this study, the BOD control effect was about 38 % in the sewer with the separation wall, whereas it showed about 24 % in the sewer without it. In this case, it was anticipated that the high pollutant control effect would be expected if the separation wall was installed in the combined sewer.
