| 中文摘要 |
| 采用三元电极,对垃圾焚烧厂渗滤液的生化-混凝出水进行了电解Fenton法处理COD反应动力学研究.结果表明:电解Fenton反应的COD降解曲线符合拟三级反应动力学,t时间的COD出水浓度可表示为:ct=(2kt+c0-2)-0.5.通过对不同工艺条件下电解Fenton法对渗滤液的COD降解曲线的统计分析,得出以电流密度、pH值、进水COD浓度为影响因子的k值经验模型.并将动力学模拟的COD出水值与实际运行的测量值进行比较,认为该模型可以较好地模拟电解Fenton法进行垃圾焚烧厂渗滤液后续处理的效果. |

| SPR electrode was used in Electrio-Fenton treatment on the effluent from biological and coagulative treatments of solid waste incinerator leachate,at the same time,the kinetics model for the COD effluent concentration were set up.The result indicated that the disposal curve of COD confirm to the pseudo third order kinetics,and the formula is ct=(2kt+c0-2)-0.5,in which the ct is the COD concentration of treatment effluent.With the statistical analysis to the disposal curve of COD from Electro-Fenton treatment in different conditions,the experience mathematics model of k value was set up,in which the current density,pH value and COD concentration of influent are effective factors.Moreover,with the comparison between the simulative COD of effluent and the experimental results,it was showed that this kinetic model could be used to investigate the COD disposal efficiency of Electro-Fenton treatment on the effluent from biological and coagulative treatments of solid waste incinerator leachate preferably. |
