高含盐工业废水处理技术研究进展

Research Progress in Treatment Technology of High Salt Industrial Wastewater

现代工业生产的工业废水往往含有超量的有机危害物或过量的盐、酸碱等,在对此类废水进行处理时,传统的方法将无法起到有效的作用。且由于此类废水同样不适宜微生物的生长,利用微生物进行污水处理的方式也受到很大的局限。对于这种工业排污废水,在实现有机物的降解之外,还需要实现无机盐和废水的分离来达到排污标准。对现在针对高含盐废水的成熟处理技术进行了总结,介绍了几种常见处理技术的特点及应用,以及他们在实际高盐工业废水处理中的作用和一些问题。通过对现有高盐废水的处理技术的分析和了解,可以针对不同类型的高盐废水使用不同的处理方式以达到最大的经济效应,并且对实现排放量最小化具有重要意义。

Industrial wastewater from modern industrial production often contains excessive amounts of organic hazards or excessive salts,acids and bases,etc.Traditional methods will not be effective in the treatment of such wastewater.The use of microorganisms for wastewater treatment is also lim-ited by the fact that such wastewater is also unsuitable for the growth of microorganisms.In addition to degradation of organic matter,separation of inor-ganic salts and wastewater is required to meet the discharge standards.The nowadays mature treatment technologies for high saline wastewater is sum-marized,and the characteristics and applications of several common treatment technologies are introduced,as well as their roles and some problems in the actual high salt industrial wastewater treatment.By analyzing and understanding the existing treatment technologies for high salt wastewater,it is possible to use different treatment methods for different types of high salt wastewater to achieve the maximum economic effect,and it is important to re-alize the minimization of emissions.
