电渗析法浓缩海水制盐的应用及发展

Application and Development of Salt Production from Concentrated Sea Water by Electrodialysis

近年来,随着市场放开,产业结构的调整,工业化、城镇化建设的不断完善,沿海土地资源日趋紧张,传统海盐产业土地面积利用率低、受气候影响因素影响大、效益产值低下的问题日趋明显,未来盐田面积将会不断减少,海盐工业的技术革新势在必行。文章主要阐述电渗析技术原理、优劣以及在浓缩海水制盐方面的应用发展。

In recent years,with the opening of the market,adjustment of industrial structure,continuous improvement of industrialization and urbanization,the coastal land resources was increasingly tense. The problems also became increasingly obvious that low utilization rate of land area,traditional sea salt industry affected by the climate factors big and the benefits of low output.Therefore,the future salt field area will continue to reduce,which sea salt industry of technological innovation is imperative. It mainly described the principle of electrodialysis,the advantage and disadvantage of the electrodialysis,and its application in concentrated seawater production.
