摘　　要：本文采用电解氧化法对垃圾渗滤液进行了预处理和深度处理研究。实验结果表明:电解氧化过程中,NH3-N优先于COD被氧化去除。当电流密度较小时,用电解法对垃圾渗滤液进行预处理,垃圾渗滤液中COD、NH3-N的去除效率很低,增大电流密度有助于增强电解效果,当电流密度为50.0mA/cm2时,电解5小时COD去除50%,氨氮去除100%。用电解法对垃圾渗滤液进行深度处理,电流密度较小时,渗滤液中COD、NH3-N即可呈现稳定降解的趋势。In this paper,the electrolysis oxidation is adopted as pretreatment and advanced treatment of landfill leachate.The experiment results show that in the process of electrolytic oxidation,removal of NH3-N is preferential to that of COD.When the electrolysis oxidation is adopted at a small current density as pretreatment of landfill leachate,the removal efficient is very low.Increasing the current density will contribute to strengthen the electrolysis result.Actually when the current density of electrolysis is...
