芬顿氧技术处理难降解有机废水的研究进展

A Review on Fenton Oxidation for Recalcitrant Wastewater Treatment

芬顿氧化是处理难降解有机物的常用技术。然而,传统的Fenton氧化技术具有一些缺点,例如严格的pH范围、铁泥的产生等限制了其应用范围。流化床-芬顿、非均相芬顿和均相络合芬顿等新型芬顿技术可克服传统芬顿技术存在的问题。本文对这几种新型芬顿技术在难降解有机物中的应用进行了回顾和总结,促进新型芬顿技术在难降解有机物废水中的应用。

Fenton oxidation is an effective technology for the degradation of recalcitrant organic pollutants. However, conventional Fenton oxidation possesses some drawbacks such as the requirement of acidic pH condition, production of iron sludge and requirement of high chemical inputs. New strategies such as heterogeneous Fenton, fluidized bed Fenton, homogeneous chelate-Fenton have been studied as possible solutions to these limitations. This paper reviews the current research progress of recalcitrant organic pollutants removal using the new strategies to promote the Fenton technologies in wastewater.
