This study selected two typical antibiotics,roxithromycin and ofloxacin,as well as two traditional wastewater treatment systems for research.The removal rate of antibiotics was obtained by monitoring the con-centration of antibiotics in each treatment stage of sewage treatment plant through the establishment of liquid chromatography and mass spectrometry.The data indicate that at a normal temperature of 25℃,the aerated biofil-ter system outperforms the modified sequential batch reactor system in the removal of roxithromycin and ofloxa-cin,with removal rate reaching 89.06％and 87.49％,respectively.Additionally,compared to normal temperature conditions,the removal efficiency of the modified sequential batch reactor system significantly decreases at a low temperature of 10℃,with a decrease of 28.72％,whereas the aerated biofilter system is less sensitive to tempera-ture change,showing little variation in removal rate.
