纳滤膜对酚类物质截留特性研究

Research on retention characteristics of phenolics with nanofiltration membrane

研究了纳滤膜处理地表水中微量酚类内分泌干扰物在长时间运行下的稳定性,结果表明,NF-90纳滤膜分离酚类内分泌干扰物,较长时间运行下的膜通量稳定在8.7 L/(m2.h)左右;酚类内分泌干扰物的截留率稳定在90%以上。

The paper researches the stability of trace phenols secretion disruptor in long-term operation in the treatment of the surface water with nanofihration membrane, proves by the result that in the secretion disruptor of phenolic of NF-90 nanofiltration membrane, the stability of mem- brane flux is about 8.7 L/（ m2 h） in longer time operation, and the retention rate stability of the phenols secretion disruptor is more than 90%.
