Abstract：
Thermal desalination evaporation of high-salt wastewater has been widely used in industry because of the proposed concept of \'zero liquid discharge\'. However, due to the high content of Ca2+ and Mg2+ in high-salt wastewater, the heat exchanger, as the main treatment equipment, suffers from serious scaling problems. This review presents descaling and scale inhibition technologies of high-salt wastewater. The advantages and disadvantages of various technologies are summarized and analyzed to provide theoretical support for the research of descaling and anti-scaling of heat exchangers with high-salt wastewater. In future industrial development, the synergistic application of electromagnetic water treatment technology and scale inhibitors can significantly improve the anti-scaling effect, which can reach over 95% stably. Furthermore, the addition of a physical field can also expand the application range of scale inhibitors.
摘要：
由于提出了“零液体排放”的概念，高盐废水的热脱盐蒸发在工业中得到了广泛的应用。然而,由于高盐废水中Ca2+和Mg2+的含量较高,热交换器,作为主要的处理设备，遭受严重的结垢问题。本文综述了高盐废水的除垢和阻垢技术。总结和分析了各种技术的优缺点，为高盐废水换热器除垢防垢研究提供理论支持。在未来的产业发展中,电磁水处理技术与阻垢剂的协同应用可显著提高阻垢效果,可以稳定达到95%以上。此外，物理场的加入还可以扩大阻垢剂的应用范围。
