摘　　要：通过CODCr降解动力学、羟基自由基和可溶性亚铁和总铁含量的变化以及循环伏安曲线研究了氧化石墨烯强化Fenton体系处理制浆中段废水的机理。结果表明:在强化Fenton体系中,一级反应速率常数k值(0.03949 min^(-1)),体系初期的.OH含量及其利用效率和正负向电流对应的区域面积(1.15×10^(-5))均要明显高于传统Fenton体系,并且该体系处理过程中可溶性总铁和亚铁含量可以始终维持在一个合适的水平,更加有利于废水处理效果的提高。在此基础上,综合分析了强化Fenton体系处理制浆中段废水的机理。In this paper,the mechanism of graphene oxide strengthened Fenton system for the treatment of mid-stage pulping wastewater was investigated by CODCr degradation kinetics,changes of hydroxyl radicals and soluble ferrous and total iron content,and cyclic voltammetry curves.The results show that in the enhanced Fenton system,the first-order reaction rate constant k value(0.03949 min^(-1)),the∙OH content and its utilization efficiency and the area corresponding to the positive and negative currents in the early stage of the system(1.15×10^(-5))are significantly higher than those of the traditional Fenton system,and the soluble total iron and ferrous content in the treatment process of the system can always be maintained at a suitable level,which is more conducive to the improvement of wastewater treatment effect.On this basis,the mechanism of strengthening Fenton system for treating mid-stage pulping wastewater was comprehensively analyzed.
