摘　　要：对农村苦咸水采用纳滤膜软化技术制备饮用水,出水水质符合《生活饮用水卫生标准》。在较低的操作压力(≤0.9 MPa)下,工艺对苦咸水的总脱盐率大于91%,水回收率可以达到70%以上,制水成本约1.14元/m3。系统长期运行稳定,产水量基本保持恒定,操作压力低,能耗低,是一种适合于农村苦咸水淡化的可行性技术。Nanofiltration(NF) membrane softening technique was used for the treatment of brackish water in rural area,and the treated water quality could meet the Standards for Drinking Water Quality.The total desalinating rate was more than 91% under low operational pressure(≤0.9 MPa),recovery of water could be over 70%,and the cost of water production was about 1.14 Yuan/m3.It was a feasible technique for brackish water desalination suitable in rural area with long-term stable operation,constant water production,low operational pressure and low power consumption.
