摘　　要：研究了用UV-Fenton法处理皂素废水的宏观动力学模型。试验证明,UV-Fenton法处理皂素废水的曲线符合三级反应动力学。通过对试验数据进行拟合,得出系统的pH值、反应时间、H2O2投加量和Fe2+浓度对废水中COD降解率的经验模型方程。经过比较动力学模拟的COD出水值与实际运行的测量值,相关性较好,可用于指导实际废水处理。The macro-dynamic model describing the saponin wastewater treatment by UV-Fenton process was studied. The results of the test showed that, the disposal curve of COD through the said process treatment followed the third order kinetic equation, with the statistical analysis of the experimental data, the experience mathematics model simulating the effects of pH value, reaction time, dosage of H2O2 and Fe^2＋ concentration on COD degradation was set up. As the relativity between the kinetic simulant COD concentration in the effluent water and the actual operation result was good, the said technology could be used in actual wastewater treatment.
