摘　　要：在氙灯照射下,采用光-Fenton工艺对废纸制浆废水进行了处理,并对其反应过程进行了动力学模型的研究.实验结果表明:光-Fenton反应可有效矿化废纸制浆废水中的有机物,且其矿化过程符合一级反应动力学,速率常数与H_2O_2、FeSO_4和温度有关.在本实验条件范围内,求得了光催化技术降解废纸制浆废水的模型,并通过实验验证表明,该模型能很好反映光-Fenton工艺对废纸制浆废水TOC的去除.In this research, the treatment of wastepaper pulp effluents by photo-Fenton has been carried out under the irradiation of xenon, and the reaction kinetic model of TOC removal was investigated. From this study, the photo-Fenton technology has been proved to be highly effective for the treatment of such effluents. The reaction rate is related to Fenton reagent doses and temperature. The kinetics equation for the oxidation reaction of wastepaper pulp effluents was established and which is found to suit the experimental data quite well.
