采用MBR和纳滤集成处理工艺对垃圾渗滤液进行了处理试验,研究了纳滤作为终端处理技术的处理效果。结果表明,纳滤对COD、色度的脱除情况很好,试验过程中膜性能稳定,透过通量和脱盐率的变化不大。纳滤的显著效果使其在垃圾渗滤液处理领域具有极大前途。
A integrated treatment technique including of MBR and nanofiltration (NF) are used for landfill leachate treatment. The treatment performance of NF using as terminal technology has been investigated. The results show that: The performance of COD and colour removals from the leachate were excellent in NF process. The membrane capabilities shown as permeate flux and desalination ratios kept stable. The nanofiltration (NF) seems to be one of the most promising and efficient methods among the processes for landfill leachate treatment.
