摘要: 高级氧化技术和活性炭纤维吸附技术都是修复有机物污染水体极具前景的技术,两者联合,发挥协同作用是近些年水处理技术发展的趋势。笔者综述了活性炭纤维联合二氧化钛光催化技术,低温等离子技术,臭氧氧化技术,芬顿技术以及电化学氧化技术水处理体系的研究进展,探索了这些体系的处理对象、处理效果、污染物降解机理,重点介绍活性炭纤维在富集有机污染物分子方面扮演的关键角色。Abstract: Advanced oxidation technologies and activated carbon fiber (ACF) adsorption are promising for the remediation of water contaminated with organic compounds that are not easily removed. This review provides a general overview of the research and development of advanced oxidation technologies, including photocatalytic oxidation with TiO2-loaded ACFs, plasma oxidation, ozonation, Fenton oxidation and electrochemical oxidation. The target pollutants, treatment performance and degradation mechanisms for these technologies are detailed. ACFs play a key role in the enrichment of organic pollutants near TiO2 active sites and a combination of ACF adsorption with TiO2 photocatalytic oxidation creates a synergistic effect in water treatment.
