- Abstract:
- Two practical wastewater treatment systems (MSBR and BAF) and a multi-stage A/O- MBBR pilot treatment system were applied to treat seven typical pharmaceuticals including SM1, SMZ, TC, ROX, OFL, CF and AP. Their concentrations in different units of the treatment system were determined by HPLC-MS, and the removal effects of different pharmaceuticals by different treatment systems were investigated. For MSBR system, the removal efficiency of seven pharmaceuticals in descending order was as follows: AP, CF, OFL, TC, ROX, SM1 and SMZ, for BAF system was CF, ROX, AP, OFL, TC, SMZ and SM1, and for multi-stage A/O-MBBR pilot system was AP, CF, OFL, ROX, TC, SM1 and SMZ. There was no significant difference in the removal efficiency of AP, CF, OFL and TC among the three systems. The SM1 removal efficiency of the BAF system was only 6.8%, which was significantly lower than that of the other two systems. The SMZ removal efficiency of the multi-stage A/O-MBBR system was only 10.75%, which was significantly lower than that of the other two systems. The ROX removal efficiency of the BAF system was 92.9%, which was significantly higher than that of the other two systems.
