Treatment of landfill leachate by a modified slow sand filtration

  • 摘要: 为了对慢滤池处理垃圾渗滤液工艺的基本参数进行研究,实验采用改良的小试规模的慢滤池模型,处理来自济南生活垃圾卫生填埋场中后期年龄段高浓度的垃圾渗滤液。重点考察活性炭粉末添加层的厚度、细粗滤料配比以及滤料层上部水层的高度等诸多因素对系统去除污染物效果的影响。实验结果表明,在垃圾渗滤液经过预处理进入慢滤池系统之后,此时调节细粗滤料配比例为2,水层高度为30 cm,活性炭粉末添加层厚度为1 cm,使得系统对各种污染的整体去除效果较好。此时,氨氮、总磷、浊度、色度和COD的去除率分别为75%、65%、90%、97%和81%。
    Abstract: In order to investigate basic parameters of the filtration process for treatment of landfill leachate,a small-scale and modified filter was designed.It was used to treat the high concentration leachate from Jinan Sanitary Landfill.Typical factors were investigated about how they impacted removal of pollutants.They contained thickness of active carbon layer,filter ratio and height of the water layer above the filter.Results show that the pre-conditioned leachate can get much better removal,under followings conditions:the ratio of fine to coarse filter of 2,water height of 30 cm,and activated carbon powder layer of 1 cm.At the point,the removal rates of nitrogen,phosphorous,turbidity,color and COD were 75%,65%,90%,97% and 81%,respectively.
