盐水冷冻淡化研究

STUDY ON DESALINATION OF SALT WATER BY THE REFRIGERATION METHOD.

进行了低浓度盐溶液的冷冻及含盐冰的部分融化实验 ,实验表明柴达木盆地盐湖区的盐水可通过自然冷冻实现浓淡分离 ,盐溶液自然冷冻以及含盐冰部分融化的脱盐效果都有相应的最适宜温度范围 ,所以随着冷季温度的变化处理相应浓度的盐水才能取得最佳效果。

The experiments of the refrigeration of diluted salt water and the partial melting of salt-containing ice to acquire fresh water have been done.The results indicate that the salt water in the lake areas of the Chaidam Basin can be desalinated.To achieve ideal effects for the desalination by the natural refrigeration-partial melting method,the optimum range of temprature must be provided.Therefore,processing certain concentration of salt water in accordance with the variation of temperature in the freezing weather,the best separation results can be obtained.
