다국어 초록 (Multilingual Abstract)

The objective of this study is to investigate the characteristics of biological activated carbon(BAC) beds on the removal of volatile and synthetic organic chemicals, such as alkyl benzen sulfornate(ABS), trihalomethane formation potential(THMFP), UV-254 absorbance(E_(254)), and so on, and to propose the formulas of predictive model of effluent quality by the BAC beds. This study was carried out at Water Treatment Plants(WTPs) located at the Nak-dong river basin. The results showed that the removal rates of the BAC were in the range of 65-80% for ABS, 60-70% for THMFP, 55-75% for E_(254) absorbance, and 50-65% for KMnO₄ consumption, respectively. For a model predicting for the water quality treated by the BAC beds obtained from sequential experiment in the WTPs, based on the results compared the calculated values of predictive equation with the one of pilot-plant experiment, the co-relationship degree for their values revealed a relatively good of approximately 82-87% regardless of the media size of the activated carbon and an adsorbed substances.
