本文以钱塘江潮汐咸水为研究对象，将纳滤膜集成技术用于潮汐咸水制备饮用水。通过对纳滤膜选择与性能评价、中试集成工艺优化，以及500 m³/d 的纳滤集成示范系统的运行试验，结果表明：对于潮汐咸水水源，应用纳滤膜集成系统可有效脱除盐分，降低水体中的有机污染物含量，对促进潮汐地区的饮水安全具有保障作用。

This study focused on preparing drinking water from the tidal salty water of Qiantang River by nanofiltration technology. Some commercial nanofiltration membranes were compared and the performance of optimized membrane was measured. A nanofiltration pilot-scale system with 500 m3/d was operated and optimized. The results showed that it was effective in removing the salt and reducing the organic pollutants from tidal water for nanofiltration technology, and nanofiltration could play an important role of security for drinking water.
