Abstract:

Nanofiltration technology has been used for the advanced treatment of the leachate at incineration plants and its feasibility has been studied. The results show that the removal rate of COD is between 80%-93%,and the removal rate of NH3-N is between 45%-70%. There are not many changes in its permeating flux and desalination rate. Since its stability is good，it can provide reference for the treatment of landfill leachate.

Key words: nanofiltration, landfill leachate, advance treatment, permeating flux

摘要：

采用纳滤技术对垃圾焚烧场渗滤液进行深度处理，探讨了该方法用于垃圾渗滤液深度处理的可行性。实验结果表明，COD 去除率为80%~93%，氨氮去除率为45%~70%。实验过程中膜通量和脱盐率变化不大，膜性能稳定，可为垃圾渗滤液处理提供参考。
