为获得优质饮用水,以市政自来水为原水,对以纳滤膜为核心的直饮水终端对自来水中各种杂质的去除效果以及产水的经济性进行研究。结果表明,以纳滤膜为核心的直饮水终端系统对去除饮用水中浊度、硬度、TDS、硫酸盐、氯化物以及氟化物等均具有较好的效果,且均能达到饮用净水水质标准(CJ 94-2005)的要求;出水水质口感良好,安全性高;系统产水成本低更具有经济性,适合推广使用。
In order to obtain high quality drinking water, municipal tap water is used as raw water, and the removal effect of various impurities in the tap water and the economy of water production by the direct drinking water terminal centered on the nanofiltration membrane are studied. The results showed that the direct drinking water terminal system with nanofiltration membrane as the core had good effect on removing turbidity, hardness, TDS, sulfate, chloride and fluoride in drinking water, and all of them could reach the drinking water quality Standard (CJ 94-2005) requirements; effluent quality taste good, high safety; low cost of system water more economical, suitable for promotion.
