영문 초록

This study was carried out to evaluate performance of sewage treatment facility in rural area. Average effluent concentration was 7.6mg/l BOD, 10.3mg/l COD. 4.7mg/l SS, 19.140mg/l TN. and 1.631mg/l TP. within discharge quality standard. The removal efficiency rate of BOD. COD and SS was good as 89.8%. 78.5% and 90.1 %. respectively. But that of TN. TP was very low as 25.0% and 31.4% respectvely. Average sewage flow rate was investigated by about 1.1㎥/d per household. 398 I pcd. In rainfall period. the removal efficiency rate of BOD. TN and TP was very low as 15%. 22% and 28%. respectively because of inflow and infiltration into sewer. In flowing concentration of sewage was diluted as rain is inserted into sewer and submerged facility was not operated at normal condition. Therefore it is required that the sewer will have to repair and hydraulic design for facility will have to be check. So it is necessary to support systematical. administrative measures for responsible management.
