우수토실에 설치된 월류수 제어를 위한 유입유량조절장치의 개선효과 = Improvements of Inflow Controller Installed in Storm Overflow Diverging Tank for CSOs Control

다국어 초록 (Multilingual Abstract)

This study was carried out to evaluate the performance of a inflow controller for the control of combined sewer overflows (CSOs). Because of the inflow controller could be adjusted manually by predicting the maximum amount of peak flow, the mechanical adjustment of this controller was higher than the existing fixed-type controller in field application. Standardizing the relationship between the flow and the clearance and angle of an inlet cover plate on the inflow conditions can selected to the optimum conditions for the on-site. It was concluded that BOD pollutant loading at the region in which inflow controller was installed had shown the removal efficiency rate of 42%.
