高级氧化-生物降解近场耦合技术研究现状与展望

工业革命以来，废水中持久性有机物因其复杂性、稳定性、高毒性成为水污染控制的核心对象。尽管水处理方法日新月异，但尚没有一种方法能艳压群芳：高级氧化技术在处理持久性污染物方面具有显著优势，但具有成本高、非选择性攻击、活性物种易淬灭失活的局限性；生物处理普适性强、抗冲击能力好，但对难降解污染物处理具有局限性。高级氧化生物降解近场耦合技术（ICAB）有机结合了高级氧化与生物降解的优势，解决了二者单独作用的局限问题，已证明能有效降解与矿化氯酚、抗生素、染料、硝基苯、多环芳烃等多种有机物。综述了高级氧化生物降解近场耦合技术的概念与特征、核心组成、优势与应用现状，及其在载体材料、活性物种淬灭和高传质反应器设计方面的瓶颈问题，并对其运用于实际水处理的未来发展进行了展望。论文旨在推广ICAB新技术在难降解有机废水处理领域的应用与发展。

Research status and prospects of intimately coupled advanced oxidization and biodegradation

Since the Industrial Revolution, persistent organic compounds (POPs) in wastewater have been at the heart of water pollution control due to their complexity, stability, and high toxicity. Despite the rapid development of water treatment methods, there is no single method that can stand out from the crowd:advanced oxidation technology has significant advantages in the treatment of POPs, but it has the limitations of high cost, non-selective attack, and easy quenching and inactivation of active species; biological treatment is universal and has good impact resistance, but it has limitations in the treatment of difficult-to-degrade pollutants. Intimately coupled advanced oxidation and biodegradation (ICAB) technology organically combines the advantages of advanced oxidation and biodegradation, solves the limitation of their individual action, and has been proved to be effective in degrading many organic substances such as mineralized chlorophenols, antibiotics, dyestuffs, nitrobenzene, polycyclic aromatic hydrocarbons and so on. This paper reviews the concept and features, core components, advantages and current applications of the intimately coupled advanced oxidation and biodegradation technology, as well as its bottlenecks in terms of efficient quenching of carrier materials, active species quenching and high mass transfer reactor design, and looks forward to the future development of its application in practical water treatment. The aim of the paper is to promote the application and development of new ICAB technology in the field of treatment of non-degradable organic wastewater.
