高盐有机化工废水处理技术分析

Analysis of Treatment Technologies for High-salinity Organic Chemical Wastewater

化工生产过程中产生的高盐有机废水具有成分复杂、难处理的特点,无法通过单一的处理技术进行有效处理。对现有高盐有机化工废水主要处理技术进行探讨和分析,综述各技术研究进展,并结合实际高盐有机化工废水处理工程案例进行分析。指出多项工艺集成是高盐有机化工废水处理的发展方向,如采用"预处理+蒸发/焚烧"的集成工艺,以实现废水中盐、水资源的综合利用。

The high-salinity organic wastewater from industrial production process is complex and refractory,and it cannot be effectively treated by a single treatment technology.The research progress of main treatment technologies for highsalinity organic wastewater was reviewed.Moreover,project cases were also analyzed.It was pointed out that process integration was the development direction of high-salinity organic wastewater treatment.For instance,the integrated process of pretreatment and evaporation or incineration was employed to realize the recycling of salt and water in wastewater.
