摘要:

纳滤作为一种新型分离技术在处理废水的同时能够回收有用物质因而在废水处理中得到了越来越广泛的应用。首先简介了纳滤膜分离技术的原理及特点然后论述了纳滤膜的分离机理接着介绍了用于表述膜的结构与性能之间关系的空间电荷、固定电荷和细孔等数学模型最后对纳滤膜在生活污水、石油工业废水、化学工业废水、食品工业废水、造纸废水、印染废水、酸洗废液、重金属废水和电厂二次废水处理中的应用作了较全面的综述。

关键词: 纳滤, 纳滤膜, 分离技术, 废水处理

Abstract:

As a new kind of separation technology nanofiltration can reclaim the useful substance while treating the wastewater.It is applied widely in the wastewater treatment.The principles characteristics and separation mechanism of nanofiltration are described.The space charge modelfixed-charge model and pore model which could narrate the relation between the structure and performance are illuminated.Then the application of nanofiltration membrane to sanitary waste petrochemical wastewater chemical wa stewater food stuff wastewater pulp and paper industrial wastewater printing and dyeing wastewateracid washing wasteheavy metal waste and secondary effluent of power station are summarized.

Key words: nanofiltration, nanofiltration membrane, separation technology, wastewater treatment
