臭氧活性炭、纳滤联用制取优质饮用水的中试研究——纳滤优化运行研究

Pilot Study on Producing High-quality Drinking Water by Combined Process of Ozonation,GAC and Nanofiltration--The Operational Optimization of Nanofiltration in Pilot Process

以臭氧活性炭、纳滤联用制取优质饮用水时,纳滤的优化运行是整个工艺能否正常运行的关键所在。针对这一问题,研究了工艺中纳滤膜通量、回收率等重要参数特性,分析了纳滤膜污染和劣化因素及控制措施,为工程应用提供了依据。

When adopting the combination of ozonation, GAC and nanofiltration to produce high-quality drinking water, the operational optimization of nanofiltration was the key factor for the whole process. In the face of this problem, the specifications of membrane flux and recovery were researched in this paper. The effective factors and controlling methods for membrane pollution and fouling were also analyzed in detail. These test results were used as the basic data of engineering practice.
