| 中文摘要 | This study assessed the potential of ozone for the degradation of nine commonly used veterinary antibiotics (five sulfonamides, three tetracyclines, and one macrolide) in swine wastewater pretreated by sequencing batch reactor (SBR). The apparent second-order rate constants for the reactions of selected antibiotics toward ozone in Milli-Q water (k(O3) at pH 7.0 and T = 20 degrees C) were determined by competition kinetics as follows: sulfonamides [(1.9-6.2) x 10(6) M-1 s(-1)], tetracyclines (6.9 x 10(6) to 1.7 x 10(7) M-1 s(-1)), and tiamulin (3.8 x 10(5) M-1 s(-1)). The antibiotics could be quickly degraded by ozone in the SBR effluent with degradation rates following the order of their k(O3) values. In the SBR effluent, the dissolved organic materials strongly competed for oxidants against antibiotics, while the suspended solids had insignificant influence on antibiotics degradation. The reaction mechanism was primarily direct oxidation via ozone rather than indirect oxidation via hydroxyl radicals. Overall, ozonation is a feasible polishing process, subsequent to biological treatment, for removal of residual antibiotics from swine wastewater. DOI: 10.1061/(ASCE)EE.1943-7870.0000404.
