摘要
垃圾渗滤液具有高COD浓度、高氨氮、高重金属的特点,直接采用常规生物方法难以使处理过程正常运行。物化法作为垃圾渗滤液生物处理的预处理工艺,可降低渗滤液中的生物毒性,为后续生物处理提供良好条件。因此,对垃圾渗滤液预处理方法研究具有重要的理论意义和工程实践意义。
Landfill leachate has the characteristics of containing high concentration of COD, heavy metal and ammoniacal nitrogen. Traditional biological techniques can not make the treatment process run in gear. As the pretreacment of landfill leachate, physical chemistry techniques can reduce the biological toxicity so as to providing a good condition for following biological treatment. Therefore, it is significative to study on pretreatment of landfdl leachate by physical chemistry techniques which can make great sense in theory and practice of engineering.
