我国北部沿海地区缺水问题十分严重,但冬季在渤海及黄海北部形成较大范围的海冰。海冰因其成冰过程中盐分大量析出而盐度很低,可能成为解决这些地区缺水问题的重要淡水资源。论文根据实地观测和室内不同盐度海水的实验分析,阐述了渤海海冰盐度变化和海水成冰脱盐过程,并采用二次成冰脱盐和离心脱盐等方法,分析了海冰经进一步人工淡化的可能性,探讨了海冰作为淡水资源的可利用价值。
The problem of water shortage in the northern coastal areas of our country is very serious, but a large range of sea ice is formed in the Bohai Sea and northern part of the Yellow Sea in winter. Because of the large amount of salt precipitation during the ice formation, the low salinity of sea ice may be an important freshwater resource to solve the water shortage problem in these areas. Based on the field observations and the laboratory analysis of different salinity seawater, the sea ice salinities in the Bohai Sea and sea ice icing desalination process are expounded. By means of secondary icing desalination and centrifugal desalination, the sea ice is further artificially desalinated The possibility of using sea ice as a freshwater resource is explored.
