高盐废水处理技术综述

Rview on High Salt Wastewater Treatment Technology

随着各行各业的快速发展,用水量猛增,因此产生了大量含盐废水,且废水成分复杂,含盐量高。含盐废水对环境污染很大,必须处理达标之后排放。综述了有关高盐废水处理技术并对其进行优缺点分析。目前处理高盐废水的方法有:膜蒸馏法、自然蒸发法、机械蒸汽再压缩蒸发法、多效蒸发法、铁碳微电解法、适盐生物法等,及其工业应用实例,为高盐废水的处理工程提供参考。

With the rapid development of all walks of life, water consumption increases sharply, Saline wastewater is very polluting to the environment and must be treated and discharged after reaching the standard. The treatment methods of high salt wastewater were summarized and their advantages and disadvantages were analyzed. At present, the methods of treating high-salt wastewater include membrane distillation, natural evaporation, mechanical steam recompression evaporation, multi-effect evaporation, iron-carbon micro-electrolysis, salt-appropriate biological method, etc, and the examples of their industrial applications provide reference for the treatment of high-salt wastewater.
