摘　　要：随着药物和个人护理用品(PPCPs)广泛使用,其对水体生态系统和人类健康的潜在威胁日益显著,抗抑郁药物因其高检测频率和持久性成为研究的热点之一。近年来,针对水体中抗抑郁药物污染的控制和去除,国内外学者提出了多种处理技术。系统综述了抗抑郁药物在环境水体中的迁移转化规律及其生态毒性,重点分析了常规水处理工艺的不足与高级氧化技术(AOPs)的最新研究进展,特别是UV/氯联合高级氧化工艺的应用潜力。综述发现,抗抑郁药物在自然环境中的降解效率较低,通过吸附、生物降解或光降解等途径仅部分去除,而传统水处理技术如活性污泥法和臭氧氧化存在去除率低、副产物生成等问题。高级氧化技术通过产生高活性羟基自由基(·OH)和氯基自由基(·Cl)实现高效降解,显示出显著优势。其中,UV/氯工艺凭借高效性和经济性,成为近年来研究的热点。研究表明,该工艺对典型抗抑郁药物的去除率可达95%以上,并能有效减少二次污染,但其在复杂水质条件下的适应性仍需进一步研究。梳理了UV/氯工艺的反应机理、自由基生成规律及主要影响因素,归纳了现有研究的技术瓶颈和改进方向,并提出了通过优化工艺参数、联合生物处理及拓展实际应用场景的建议,为饮用水处理和污水处理新型污染物控制提供科学参考。The widespread use of pharmaceuticals and personal care products(PPCPs,including antidepressants,and other compounds)has raised significant concerns about the impact on aquatic ecosystems and human health.Among these,antidepressants are particularly concerning due to their frequent detection,persistence in the environment,and potential harmful effects.Consequently,antidepressants have become a major research focus within the study of PPCPs.In recent years,various techniques have been proposed to address the challenge of controlling and removing antidepressant contaminants from water bodies.However,many of these methods face significant limitations.This review systematically examines the environmental fate and ecotoxicity of antidepressants in aquatic environments,highlighting the challenges posed by conventional water treatment methods,as well as the latest advancements in advanced oxidation processes(AOPs),particularly the UV/chlorine combined oxidation technology.Antidepressants are poorly degradable in natural aquatic environments.Removal is often incomplete and depends on processes such as adsorption,biodegradation,and photodegradation.Conventional water treatment technologies,including activated sludge systems and ozonation,demonstrate limited efficacy in removing antidepressants and may even lead to the formation of toxic by-products.In contrast,advanced oxidation processes,which generate highly reactive hydroxyl radicals(·OH)and chlorine radicals(·Cl),have proven much more effective at degrading these contaminants.Among the various AOPs,the UV/chlorine process has gained significant attention for its ability to achieve high degradation efficiency at a reasonable cost.Studies have shown that the UV/chlorine process can effectively remove over 95%of commonly found antidepressants in water,significantly reducing the risk of forming toxic by-products.However,while the UV/chlorine process displays promising results,further research is needed to enhance its adaptability to complex water matrices.The presence o
