冷冻浓缩技术在水处理行业中的研究与应用

Research and Application of Freeze Concentration in Water Treatment

冷冻浓缩技术是在低温环境下物理化学相平衡理论为基础,在实现污染物浓缩同时得到再生水的一种新型水处理技术。总结了此技术目前在工业废水处理、海水淡化和垃圾渗滤液处理领域的研究与应用,同时对比了此技术相较于常规水处理技术所具有的诸多优势,最后分析目前其存在的不足,并对未来发展方向进行了展望。

Freeze concentration is a new type of water treatment technology, which is based on the theory of physical-chemical phase equilibrium in low temperature and can achieve the concentration of pollutants and obtain reclaimed water at the same time. In this paper, the current research and application of freeze concentration for industrial wastewater, seawater desalination and landfill leachate were summarized, and advantages of this technology were compared. Finally, the existing shortcomings were analyzed, and the future development direction was prospected.
