Abstract
Many researches has been conducted as extreme rainfall in hydrology and extreme rainfall analysis is not proper for determination of CSOs treatment capacity. In this study, runoff is calculated by tranformation from rainfall to runoff according to Interevent Time Definition. The capacity of sewage treatment plant is designed by 3 times of DWF(Dry Weather Flow) and the efficiency of present sewage treatment plant is very low becauseat at present. Also, The sewage treatment plant can not control CSOs. In this research, the pollution load is calculated by EMC(Event Mean Concentration) and pollution concetration of total runoff is a standard deciding suitablility of present sewage treatment plant. Finally, CSOs treatment capacity is determinated considering pollution load.
Keywords
