【Abstract】 Deep sea water is far away from industrial and man-made pollution. Its mineral content is rich and its composition is stable. It has higher extraction, processing and application advantages. With deep sea water as raw material, it can produce deep-sea aquatic products with higher quality than land water and surface sea water products. Electrodialysis technology has shown good economy in treating medium salinity solution. It has many advantages, such as low energy consumption, high efficiency, high raw water recovery rate, no pollution to the environment, flexible equipment design and application, convenient maintenance, long service life, etc. It chooses different current and voltage conditions to carry out the application research of electrodialysis to separate deep seawater, and investigate the concentration effect under different current and voltage conditions, By optimizing the concentration and separation process of electrodialysis with different selective exchange membranes, the problem of scaling of multivalent ions in deep seawater concentration process was solved.更多还原
