摘要:

Fenton氧化属于高级氧化技术,具有反应时间短、降解效率高、操作简单等优点,是处理难降解有机废水方法中最具应用前景的方法之一。然而,传统Fenton氧化法存在一些技术缺陷,包括反应pH范围过窄、产生含铁污泥以及H2O2投加量较高等。针对Fenton氧化的局限性,综述了解决这些问题的最新技术措施,包括拓展Fenton初始反应pH至中性或碱性、减少铁泥产生及铁泥循环利用、原位产生H2O2,并对每种措施的基本原理及处理难降解有机污染物的应用进行了综述。

关键词: Fenton氧化, 难降解有机废水, 原位产生H2O2, 铁泥减量, 宽pH范围

Abstract:

Fenton oxidation is an advanced oxidation technology with the advantages of short reaction time,high degradation efficiency and simple operation,so it is one of the most promising methods for the treatment of refractory organic wastewater. However,there are some technical defects in the traditional Fenton oxidation process,including the narrow pH value of the reaction,the production of iron-containing sludge and the addition of high dose H2O2 and so on. In view of the limitations of Fenton oxidation,the latest technical measures to solve these problems are reviewed in this paper,including expanding the initial pH of Fenton to neutral or alkaline,reducing the production and recycling of iron mud,and generating H2O2 in situ. The basic principle of each measure and its application in the treatment of refractory organic pollutants are reviewed.

Key words: Fenton oxidation, refractory organic wastewater, H2O2 produced in situ, iron sludge reduction, wide pH range
