| 内容記述 | This study investigated the inactivation characteristics of antimicrobial-resistant Escherichia coli (AMR-E. coli) using a combined treatment of chlorine dioxide (ClO₂) and UV-LED irradiation. Multi-drug resistant strains (5-drug and 6-drug resistant) and a non-resistant strain (ATCC25922) were examined under three treatment conditions: (1) ClO₂ alone, (2) UV-LED alone, and (3) simultaneous treatment with ClO₂ and UV-LED. ClO₂ treatment alone showed limited inactivation during the early phase of exposure (up to a CT value of 0.05 mg/L·min) for AMR strains. UV-LED treatment alone resulted in consistent inactivation rates with a rate constant of 0.75–0.85 mJ/cm²⁻¹ regardless of resistance, but AMR strains exhibited higher resistance during initial exposure. The combined treatment demonstrated a synergistic effect, achieving 1.2–2.8 times higher inactivation compared to individual methods. This enhancement is likely due to the oxidative action of ClO₂ altering UV absorption characteristics and overcoming initial resistance in AMR strains. The findings suggest that simultaneous application of ClO₂ and UV-LED irradiation significantly improves the inactivation of AMR-E. coli compared to either method alone. This study highlights the potential of this combined approach as a powerful disinfection strategy to address AMR bacteria in water treatment systems. | |||||||||
