水处理中膜分离技术的应用

Abstract

Abstract: Development history and present application situation of membrane separation technique were introduced.Applications of nanofiltration and reverse osmosis in water treatment fields，such as the desalination of sea water and brackish water and wastewater treatment，at home and abroad were summarized.And also the relevant problems，such as membrane fouling，concentration polarization，and higher cost，were pointed out.According to the selective permeability of nanofiltration membrane，the application feasibility of membrane separation technique to Mg/Li separation of salt lake brine was discussed and the relevant techniques about membrane element and supporting chemical technology were prospected.

Key words: membrane separation technique, water treatment, salt lake brine
