| ABSTRACT |
|
In this study, The effects of empty bed contact time (EBCT) and water temperature on the biodegradation of 8 synthetic fragrances (SFs) in biological activated carbon (BAC) process were investigated. Experiments were conducted at two water temperatures (7 and 18℃) and three EBCTs (5, 10 and 15 min). Increasing EBCT and water temperature increased the biodegradation efficiency of SFs in BAC column. Pentalide and ambrettolide were the highest biodegradation efficiency, but DPMI and ADBI were the lowest. The kinetic analysis suggested a pseudo-first-order reaction model for biodegradation of 8 SFs at various water temperatures and EBCTs. The pseudo-first-order biodegradation rate constants (kbio) of 8 SFs ranging from 0.1184~0.6545 min-1 at 7℃ to 0.3087~0.9173 min-1 at 18℃. By increasing the water temperature from 7℃ to 18℃, the biodegradation rate constants (kbio) were increased 1.4~2.6 times. |
