영문 초록

Biological process have the potential to remove pollutants such as biodegradable organic fraction, $NH_3-N$, ABS, etc. that may be partially removed by conventional water treatment. This study was performed to evaluate four different processes of biological pretreatment as Biological Fluidized Bed(BFB), Biological Filter(BF), Rotating Biological Contactor(RBC) and Honey Comb(HC). In a given condition it proved out that BFB and BF are prospective biological pretreatment processes because they were the most effective on the removal of organic matter and ammonia. Preozonation of raw water for biological processes increased in biodegradable organic fraction about 10-40% with 0.425-0.85 mg $O_3/mg$ DOC.
