To obtain the content level and treatment efficiency of typical antibiotics in wastewater treatment in large-scale dairy farms in Tianjin, the SPE-UPLC-MS/MS (ultra-high performance liquid chromatography tandem triple quadruple mass spectrometry combined with solid-phase extraction for pretreatment) technology was utilized to investigate and monitor seven typical antibiotics in wastewater from 12 large-scale dairy farms in Tianjin. Antibiotic residues were detected in 12 large-scale dairy farms before and after wastewater treatment. In the wastewater before treatment, the detection rates of tilmicosin (TIL), oxytetracycline hydrochloride (OTC), sparfloxacin (SPA), sulfathiazloe (STZ), ofloxacin (OFL), and sarafloxacin hydrochloride (SAR) were all 100%, whereas the detection rate of sulfadiazine (SDZ) was 83.33%. Among them, TIL and OTC were the main antibiotic components in untreated wastewater, the concentrations were 25.21 μg·L |
