Abstract:

Compared to reverse osmosis,nanofiltration is lower in operation pressure and easier in operation management,which makes it widely applied to landfill leachate treatment projects.Based on the example instance from Sichuan Province landfill leachate treatment,two kinds of application of nanofiltration to the treatment of landfill leachate are introduced.One is used as post-treatment and the other one is used for desalting the concentrated water from reverse osmosis.Four aspects to be considered about the application of nanofiltration to the rebuilt landfill leachate treatment projects are summarized in order to provide reference for the applications of nanofiltration that are newly built and in reforming to landfill leachate treatment projects.

Key words: nanofiltration, landfill leachate, wastewater treatment

摘要：

纳滤较反渗透具有更低的操作压力且运行管理方便,使得其在垃圾渗滤液处理工程中得到广泛的应用。结合四川省垃圾渗滤液处理工程实例,介绍了纳滤在渗滤液处理中的两种应用:用作后处理和用于反渗透浓水的脱盐,通过对实例的分析总结了纳滤用于垃圾渗滤液处理工程改造应该考虑的4个方面问题,为纳滤在渗滤液处理工程的新建与改造中的应用提供借鉴。
