摘　　要：随着工业化进程的加速,抗生素类污染物已成为威胁水生态系统与饮用水安全的难降解污染物。传统水处理技术难以实现其高效去除。此工作利用EAOPs和Fe(Ⅲ)协同活化S(Ⅳ),构建三元体系,高效生成·OH、SO_(4)^(·-)、O_(2)^(·-)和1O_(2)等活性物种,实现SMX的深度降解。在优化条件下,60min内去除率达84.88%。自由基淬灭实验确认多种活性物种的协同作用机制,HPLC-MS分析进一步推测了SMX的降解路径,为抗生素废水处理技术的开发提供了重要理论基础。With rapid industrialization,antibiotic pollutants have emerged as persistent contaminants,posing serious threats to aquatic eco-systems and drinking water safety.Conventional water treatment methods are insufficient for their effective removal.This study developed an elec-trochemical advanced oxidation process ternary system that synergistically activates S(IV)via electrochemical and Fe(III)processes,generating re-active species(·OH、SO_(4)^(·-)、O_(2)^(·-)and 1O_(2))for efficient SMX degradation.Under optimized conditions,the system achieved 84.88%removal within 60 minutes.Radical quenching experiments confirmed the synergistic roles of multiple reactive species,and HPLC-MS analysis clarified the degrada-tion pathways.This work offers critical theoretical insights for advancing antibiotic wastewater treatment technologies.
