摘要
对混凝技术在渗滤液处理中的应用进行总结,混凝预处理后渗滤液的B/C有所提高,可去除COD约50%以上。而用于深度处理后,渗滤液的COD去除率一般在20%左右,且往往不能达到二级排放标准。因此,从处理效果可以看出:混凝技术对新鲜渗滤液具有良好的预处理效果,且适合一些难降解物质的去除。
The application of coagulation technology in landfill leachate treatment was summarized in this paper. For the leachate after coagulation pretreatment, its B/C is increased and more than 50% COD can be removed from it; while for the leachate after advanced treatment, its COD removing rate is generally around 20% and cannot meet the class-Ⅱ discharge standard. So, it can be seen from the treatment results that the coagulation technology is of good effect on fresh leachate pretreatment and suitable for removing of non-degradation matters.
