Fenton试剂在处理难降解工业有机废水中的应用

Application of Fenton reagent in treatment of hard-degradable industrial organic wastewater

Fenton试剂作为一种高级氧化技术在高浓度、难降解和有毒有害工业有机废水的处理研究中被广泛应用,并取得了显著的成果。综述了Fenton试剂在焦化废水、垃圾渗滤液、印染废水和农药废水处理中的应用研究进展。指出:进一步开展Fenton试剂与混凝沉降、活性炭吸附、生化、光催化等方法组合处理技术的研究,减少药剂投加量降低水处理成本;拓宽pH使用范围和寻求铁离子的固定化技术,应是今后Fenton试剂处理难降解工业有机废水的发展方向。

As an advanced oxidation technology, Fenton reagent is wildly applied for the study of the treatment of the industrial organic wastewater which is high organic-containing, hard-degradable, venenous and harmful, and remarkable results has been attained. The research progress of the application of Fenton reagent in treatment of coking wastewater, landfill leachate, printing and dyeing wastewater, pesticide wastewater was summarized. It was indicated that： the direction of future development of Fenton reagent treating hard-degradable industrial organic wastewater should be： further studying the combined treatment technology of Fenton reagent and coagulation sedimention, activated carbon adsorption, biochemistry and photocatalytic degradation; reducing reagent dosage to decrease water treatment cost, extending application range of pH and seeking technology for iron ions immobilization.
