摘要

采用自然曝气生物滤床工艺处理污水处理厂尾水中抗生素,对生物滤床中抗生素的去除特点和影响因素进行研究。研究结果发现,自然曝气生物滤床能够有效地去除四环素类抗生素(58±2)%、喹诺酮类抗生素(48±20)%和大环内酯类抗生素(18±11)%。微生物降解和物理吸附是生物滤床去除抗生素的主要途径,而这两种途径的协同作用则延长了生物滤床的运行周期。结果还表明,水力负荷对抗生素的去除效率影响较大,当水力负荷为4.8～6.4m/d时,生物滤床对抗生素有较好的处理效果。此外,水质参数(水温、pH、COD浓度和硝化作用等)在一定程度上也可以影响生物滤床对抗生素的处理效果。

Abstract：

Through the use of a natural biological aerated filter for treatment of antibiotics from sewage plant effluent,the removal and influencing factors were analyzed.The results showed that the natural biological aerated filter could effectively remove tetracyclines(58±2)%,quinolones(48±20)% and macrolides(18±11)%,respectively.Microbial degradation and adsorption processes appeared to be the most important pathways for antibiotics in the natural biological aerated filter,whose synergistic effect also could extend the cycle of operation.The results also showed that the treatment of antibiotics was greatly affected by the hydraulic loading rate,and the optimal hydraulic loading rate for the removal of antibiotics in the natural biological aerated filter was 4.8-6.4 m/d.In addition,the elimination of some antibiotics was also influenced by the water quality parameters,such as temperature,pH,COD and nitrification.

Key words： antibiotics natural biological aerated filter sewage plant effluent removal efficiency hydraulic loading rate
