Research on Antibiotic Removal Effect of Traditional Sewage Treatment System
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.
