| 化学品类新污染物种类繁多，对自然生态环境和人类健康存在严重风险，是新污染物治理的主要对象。由于常规水处理工艺对新污染物的去除能力有限，如何发展绿色、经济、高效和安全稳定的净水技术成为新污染物管控的重要课题。生物炭因其丰富的表面结构与性质，具有优异的吸附和催化能力。近年来，众多科研工作者开展了基于生物炭的高级氧化技术(AOPs)去除新污染物的效能和机制研究。本文聚焦主要的化学品类新污染物，分析了生物炭结构与去除新污染物功能间的关系，综述了近年来生物炭在光催化氧化、类芬顿氧化和过硫酸盐催化氧化中的应用，并探讨了水环境条件(如pH值、阴离子和有机物等)对反应体系的影响，最后对未来相关研究中值得关注和深入探索的问题进行了总结与展望。 |
| 英文摘要: |
| Diverse chemical emerging contaminants(CECs) are the main target pollutants in the governance of emerging contaminants(ECs), which pose serious risks to the natural ecological environment and human health. Due to the limited removal capacity of ECs in conventional water treatment processes, how to develop green, economic, efficient, safe and stable water purification technology has become a vital topic for the control of ECs. Biochar has excellent adsorption and catalytic capacity because of its rich surface structure and functional properties, and in recent years, many researchers have carried out researches on the efficiency and mechanism of advanced oxidation processes (AOPs) based on biochar to remove ECs. Focused on major CECs, this paper analyzed the relationship between the structure of biochar and its function to remove ECs, and summarized the application of biochar in photocatalytic oxidation, Fenton-like oxidation and persulfate catalytic oxidation in recent years. The influence of water environmental conditions such as pH values, anions and organic matters on the reaction system was discussed. In the end, the issues worthy of attention and in-depth exploration in the future related research were summarized and prospected. |
