Comparison of Decomposition Characteristics of Tetracycline Antibiotics Using the AOP System

This study compared the treatment efficiency, total organic carbon(TOC) removal rate and power consumption of tetracycline antibiotics((tetracycline(TC) and oxytetracycline(OTC)) using Microwave-AOP and TiO₂-AOP among AOP methods. As a result of the decomposition test of TC and OTC using Microwave-AOP, 90.1 % of TC and 96.9 % of OTC were decomposed in the 20-minute reaction. In the decomposition using TiO₂-AOP, 79.1 % of TC and 83.9 % of OTC were decomposed during the 180 min reaction time. In the comparison of TOC removal efficiency, the removal efficiency was 1.6 times higher when applying Microwave-AOP than TiO₂-AOP during 180 min treatment time. In the comparison of power consumption through EE/O(Electrical Enerny per order) calculation, higher EE/O than OTC was required when TC was decomposed, and the TiO₂-AOP application could be saved 8.6 to 11 times compared to Microwave-AOP. Both microwave-AOP and TiO₂-AOP processes are considered applicable to the decomposition of TC and OTC, and TiO₂-AOP is considered to be advantageous in terms of power consumption and microwave-AOP in terms of decomposition efficiency and time.
