摘　　要：采用“浅层介质过滤—纳滤”的组合工艺,对和田某村的苦咸水进行淡化处理。工程运行结果表明,水中溶解性总固体的脱除率达到了96%,钙、镁离子和硫酸盐的脱除率超过了99%,产水水质满足《生活饮用水卫生标准》(GB 5749-2006)的要求,工程运行能耗约1.17 kW·h/m ^(3),运行成本约0.92元/m^( 3)。The“shallow layer medium filtration-nanofiltration”combined process was used to desalinate the brackish water from a village in Hetian.The operation results showed that the removal rate of total dissolved solids in water had reached 96%,and the removal rates of calcium ions,magnesium ions and sulfate had all exceeded 99%.The product water quality met the requirements of standards for drinking water quality(GB 5749-2006).The energy consumption of the project was about 1.17 kW·h/m^( 3),and the operating cost was about 0.92 yuan/m^( 3).
