동두천시 하수처리구역내 침입수/유입수 분석에 관한 연구 = Study on analyzing infiltration/inflow in sewage treatment basin of Dongduchun City

다국어 초록 (Multilingual Abstract)

To identify the characteristics of wastewater flow, we selected 6 stations representing the basin, and performed 8 times of field survey including 6 times in dry periods and 2 times in wet periods from March 8 to July 25, 2002 for the selected stations. In each survey, we conducted 24-hr water-quality sampling in the interval of 2-hr, and downloaded flow data. Using SM-Sewer, we performed infiltration/inflow (I/I) analysis for wastewater treatment areas of Dongduchun City. To determine the rank for rehabilitation of sewer system, infiltration rate was computed by dividing by mean diameter and total length of sewer for infiltration. The analysed results show Dongduchun-2 ranked as the first since the mean diameter and total length was large enough compared to the amount of infiltration. Accordingly, rehabilitation program for sewer should be gradually proceeded reflecting the rank determined based on the result of infiltration rate.
