高盐废水结晶技术及资源化利用的研究进展

Research Progress in the Crystallization Technology and Resource Utilization of High-salt Waste Water

随着中国经济发展及工业化脚步的加快,工业生产用水量和产生废水量与日俱增,在钢铁、煤化工、印染、奶制品等行业废水量尤为可观。巨大的用水量加剧了水资源的紧缺,诸多行业产生的高盐废水对环境产生严重影响。高盐废水具有来源广泛且处理难度大的特点,因而现今处理高盐废水最关键的点在于怎样经济有效且尽可能实现零排放。文章针对高盐废水结晶技术及资源化利用的相关内容展开了综合性的阐述。

With the acceleration of China’s economic development and industrialization,the water consumption and wastewater produced in industrial production are increasing,especially in steel,coal chemical industry,printing and dyeing,dairy products and other industries.Huge water consumption aggravates the water shortage,and the high salt wastewater produced by many industries has a serious impact on the environment.High salt wastewater has the characteristics of wide sources and diff icult treatment,so the most critical point of treating high salt wastewater today is how to be cost-effective and achieve zero discharge as far as possible.This paper expounds the crystallization technology of high salt waste water and resource utilization.
