非均相电芬顿技术降解抗生素废水的研究进展

Progress in the Degradation of Antibiotic Wastewater by Heterogeneous Electro-Fenton Technology

抗生素废水污染如今已成为全球最为严峻的环境问题之一,对人类的生存和生态系统的平衡都具有巨大的威胁。非均相电芬顿法作为一种可以降解抗生素污染物的高级氧化技术(advanced oxidation process, AOPs),因其氧化效率高、氧化性能强、不易产生二次污染等优点而受到广泛关注。从反应机理、催化剂、阴极材料3个方面概述了非均相电芬顿技术降解抗生素废水的研究现状和存在问题,最后对非均相电芬顿技术降解抗生素废水发展方向做出展望。

Antibiotic wastewater pollution has become one of the most serious environmental problems in the world,which poses a great threat to the survival of human beings and the balance of ecosystem.As an advanced oxidation process(AOPs)that can degrade antibiotic pollutants,heterogeneous electro-Fenton method has attracted wide attention due to its advantages of high oxidation efficiency,strong oxidation performance and low secondary pollution.The research status and existing problems of the degradation of antibiotic wastewater by heterogeneous electro-Fenton technology were summarized from three aspects of reaction mechanism,catalyst and cathode.Finally,the prospect of the degradation of antibiotic wastewater by heterogeneous electro-Fenton technology was made.
