摘　　要：采用超滤-纳滤膜集成膜技术,进行了胶州湾海水纳滤软化现场试验,筛选了纳滤膜,考察了料液流量、操作压力对纳滤膜元件运行效果的影响,评价了纳滤作为海水淡化预处理对海水中主要离子的截留效果,并进行了短期试验。结果表明超滤-纳滤膜集成技术可为淡化系统提供优质的软化水,为胶州湾地区膜法海水淡化奠定了基础。A test on spot for seawater softening by Nanofiltration（NF） integrated membrane technologies was done in Jiaozhou bay, and NF membrane for the process was selected through screening test.The effect of feed flow,operating pressure on the operating results of NF element was investigated; the removal of some main ions in seawater by NF as pretrcatment for seawater desalination was evaluated and a short-term test was carried out.The results showed that UF-NF integrated technique could provide high quality sottened water ,laying a foundation for seawater desalination by membrane process in Jiaozhou Bay area.
