| 摘 要： | 采用修正后一级反应动力学模型拟合Fenton法处理垃圾渗滤液结果,研究初始pH值、试剂比、H2 O2用量、初始浓度和温度等因素对动力学常数的影响并优化反应参数.结果表明：在考虑运行成本情况下,Fenton法处理渗滤液的最佳去除率为70.3%,此时反应条件初始pH值为3,H2O2]/TOC0]为4,H2O2]/Fe2+]为5,反应温度为室温.

Kinetics of TOC in Landfill Leachate by Fenton Process |

| Abstract: | The reaction rate constants, stimulated by the modified first-order kinetic model on treatment of landfill leachate by Fenton process, of different influencing factors such as initial pH, initial hydrogen peroxide concentration, H2 O2 ]/ Fe2+] molar ratio, temperature and initial concentration were discussed. The optimization of Fenton, while the best TOC removal was 70. 3%, was at initial pH at 3, H2O2]/TOC0] at 4, H2O2]/Fe2+] at 5 and room temperature by simultaneous consideration of economic, kinetic constant and TOC removal efficiency of leachate. |
