高盐废水单质分盐与资源化利用的研究进展

工业生产中产生的高盐废水是一类较难处理的废水,直接排放或管理不善会污染环境,且会造成资源的浪费,因此需通过经济高效的处理技术对其进行处理及资源化利用。结合目前高盐废水的处理背景,介绍了工业高盐废水的常用处理技术和单质分盐工艺,并结合工程与发明实例,分析了这些常用技术的优缺点,提出未来工业高盐废水处理研究的重要方向是解决目前组合分盐工艺中存在的弊端,并对现有工艺做了优化。

Research progress on salt separation and resource utilization in high salinity wastewater

High salinity wastewater generated in industrial production is a kind of wastewater that is difficult to be treated. Direct discharge or improper management will lead to the pollution of environment and cause waste of resources.Therefore,economic and efficient treatment technology should be adopted to treat and reuse it.Combined with the background of the treatment of high salinity wastewater,the common treatment technology of industrial high salinity wastewater and the salt separation process were introduced.The advantages and disadvantages of these common techniques were analyzed combined with engineering and invention example.Finally,it proposed that solving the defects in the current combined salt separation process and optimizing the existing process would become an important research direction for the future industrial high salinity wastewater treatment.
