库尔勒地区苦咸水自然冷冻淡化技术研究

Research on Natural Freezing Desalination Technology of Brackish Water in the Korla Area

为解决库尔勒地区农村用水紧缺问题,本文借助自然冷冻技术对苦咸水进行淡化以获得矿化度较低的淡水。实验结果表明,冷冻温度为-15℃时具有最好的经济效应,而-20℃时具有更好的处理效果。同时,随着截取淡水的比例增加,淡水矿化度急剧增加。此外,对本技术的实际应用方案进行了讨论,可通过多次结冰获得经济高效的处理效果,为减轻库尔勒地区耕种用水问题提供参考。

To address the rural water shortage in the Korla district,this paper uses a natural freezing technique to desalinate brackish water to obtain fresh water with low mineralization.The experimental results suggest that the freezing temperature has the best economic effect when the freezing temperature is-15℃,and a better productivity is at-20℃.At the same time,the salinity of fresh water increases dramatically as the fraction of intercepted fresh water increases.In addition,the practical application of this technique is discussed and the cost-effective treatment effect can be achieved by multiple freezing,which serves as a reference for alleviating the water supply problem for cultivation in Korla district.
