소규모 하수처리를 위한 도시 및 농촌하수 특성비교 = Comparisions with Domestic Sewage Quantities-Qualities from Iksan and Hameol

다국어 초록 (Multilingual Abstract)

This study was carried out in order to estimate the domestic sewage quantities-qualities from combined sewer in Iksan and Hameol. To investigate the domestic sewage quantities-qualities from combined sewer, sample were collected 2 times during this study period at ten points.
Flow rate analysis demonstrates a major morning and evening peak between 08:00∼10:00 and 19:00∼22:00, respectively.
The concentrations of BOD were in the range of 23∼340㎎/ℓ and 28∼318㎎/ℓ, respectively. The highest concentrations of BOD occurred in the point 1. The concentrations of suspended solids were in the range of 18∼330㎎/ℓ and 13∼85㎎/ℓ, respectively.
The pollution loading runoff after a rainy season decreased compared to that made before the rainy season. Comparisions with data for second survey show lower than first survey, from domestic sources, of many dilute water often regarded as having a mainly groundwater origin.
