| 摘 要： | 研究了基于PbO2/Ti阳极的三维电极法处理垃圾渗滤液。结果表明,三维电极法电化学氧化过程可有效去除垃圾渗滤液中的污染物,保持较高的电流利用效率(ICE),并提高可生化性,氯化物浓度、电流密度、绝缘物质填充量以及反应时间均对反应效果产生了一定的影响。研究还表明,三维电极反应器中进行的反应为一级反应,反应遵从关系式:dC/dt=-akC,该法可作为垃圾渗滤液的预处理工艺。

| Abstract: | The paper studied the degradation of landfill leachate by three-dimensional electrode on PbO2/Ti anode.The results indicated that the method could remove contamination in the landfill leachate effectively,keep a upper instantaneous current efficiency(ICE) and improve the biodegradability.The main influential factors consisted of Cl-concentration,current density,volume ratio of doped membrane carbon and carbon,and time of reaction.The study also indicated that the reaction in the reactor could be described by the equation dC/dt=-akC,and the method could be used as the pretreatment progress of landfill leachate. |
