摘　　要：利用冷冻离心法处理浓海水样品,并对处理前后各个水样主要离子含量进行分析。结果表明,经过多步冷冻离心,处理后的冰的主要离子含量仅为原水浓度的2%左右,而经过多次分离后的浓海水各种离子高度富集,盐度、主要离子含量均比原水样增高3倍以上。The desalinated seawater treatment employing frozen centrifugation technology was studied, and the mainly ion content before and after the processing was analyzed. The results indicate that the main ion content of ice is only about 2% compared with the original desalinated seawater after repeated frozen centrifuqation, and the ion content of residual brine is highly concentrated, the salinity and the main ion content are three times higher than the original water.
