浅析煤化工浓盐水分质“零排放”技术现状和发展趋势
|
摘要
介绍了煤化工浓盐水"零排放"处理的技术现状;探讨了目前煤化工浓盐水分质"零排放"处理过程中存在主要的技术挑战;提出废水"零排放"技术发展趋势是研究开发高盐度膜浓缩技术、有机物深度去除技术和纯盐定向结晶技术,以实现更低的处理成本、更好的系统稳定性和纯盐的良性循环。
This paper introduced the present situation of zero liquid discharge treatment technology of concentrated salt water in coal chemical industry; The main technical challenges in the process of zero discharge treatment of concentrated salt water in coal chemical industry were discussed by comparing the representative zero liquid discharge engineering cases in China's coal chemical industry; The development trend of zero liquid discharge technology was to develop high salinity membrane concentration technology, deep removal technology of organic matter and directed crystallization technology of pure salt in order to achieve lower treatment cost, better system stability and virtuous circle of pure salt.
