低温蒸发应用于工业废水零排放的现状及展望

Application Status and Prospect of Low Temperature Evaporation in Zero Discharge of Industrial Wastewater

蒸发结晶工艺是目前实现工业废水"零排放"的重要工艺,但其高成本一直制约着工业废水零排放的发展。因此,低温蒸发得到广泛应用。总结了目前常见的几种低温蒸发在工业废水零排放方面的应用现状,提出降低综合成本、提高资源化程度、合理设计工艺组合运行方案将是此领域未来研究的重要方向。

Evaporation crystallization process is an important process to achieve " zero discharge" of industrial wastewater, but its high cost has always restricted the development of zero discharge of industrial wastewater. Therefore, low temperature evaporation is widely used. This article summarizes the current application status of several low-temperature evaporation in industrial wastewater zero discharge, and proposes that reducing comprehensive costs, increasing the degree of resource utilization, and rationally designing a process combination operation plan will be important directions for future research in this field.
