【摘要】 多环芳烃（PAHs）是难降解有机污染物之一，如不妥善处理会对生态环境造成影响，严重威胁人类健康。光催化与生物降解紧密耦合（ICPB）技术集合了光催化与生物降解的优点，可提高对难降解污染物的去除率，降低中间产物毒性，具有操作简单、能耗低、处理效率高等优点。归纳了ICPB技术的技术原理、发展及其在去除废水中PAHs方面的应用，总结了不同类型PAHs在不同反应体系下可能的降解途径，提出了目前针对ICPB技术研究中仍未解决的科学问题，并对未来发展进行了展望。通过进一步研究ICPB技术的作用机制并加快新型光催化剂的研究、筛选获得对光催化环境适应性强的微生物，将有效拓展该技术在实际大规模废水处理中的应用前景。更多还原

【Abstract】 Polycyclic aromatic hydrocarbons(PAHs) are one kind of refractory organic pollutants. PAHs can affect biological environment and seriously threat human health if they are not treated properly. Intimate coupling photocatalysis and biodegradation(ICPB) technology combines the advantages of photocatalysis and biodegradation,which can improve the removal rate of refractory pollutants and reduce the toxicity of intermediate products. ICPB technology also has the advantages of easy operation,low energy consumption and high treatment efficiency. The mechanism,development and applications of ICPB technology in PAHs removal were reviewed. The possible degradation pathways of different PAHs under different reaction systems were also summarized. The unsolved scientific issues about ICPB technology were proposed and the future development was prospected. By further studying the mechanism of ICPB technology,accelerating the research of new photocatalysts and selecting microorganisms with strong adaptability to the photocatalytic environment,the application prospect of this technology in actual large-scale wastewater treatment will be effectively expanded.更多还原
