芬顿催化技术降解有机污染物的应用研究进展

Research Progress on Application of Fenton Catalytic Technology to Degradation of Organic Pollutants

随着工业化进程的不断加快,环境污染和能源短缺问题日益凸显。研究证实,高级氧化技术是解决污染问题的有效措施。本文主要论述了芬顿催化技术的降解机理,系统研究了pH、Fe^(2+)投加量、H_(2)O_(2)投加量、温度等影响因素对催化降解效率的影响;为了改善芬顿试剂存在的不足,进一步研究了类芬顿催化体系和光催化-芬顿催化协同反应体系在降解有机污染物方面的应用,为新能源利用和环境修复等方面的研究提供了理论支持。

With the acceleration of the industrialization process,the problems of environmental pollution and energy shortage have become increasingly prominent.The research proves that advanced oxidation technology is an effective measure to solve the pollution problem.The degradation mechanism of Fenton catalytic technology was discussed,and the effects of pH,Fe^(2+)dosage,H_(2)O_(2)dosage,temperature and other factors on the catalytic degradation efficiency were systematically studied.In order to improve the shortcomings of Fenton s reagent,the application of Fenton-like catalytic system and photocatalytic Fenton-catalytic collaborative reaction system in the degradation of organic pollutants was further studied,which provided theoretical support for the research of new energy utilization and environmental remediation.
