摘要(Abstract)：

在说明石灰-纯碱法脱硫废水软化工艺局限性的同时,分析了制盐行业中石灰-烟道气法卤水净化的工艺特点,探讨将石灰-芒硝-烟道气工艺应用于脱硫废水软化处理,并从理论上证明了该技术路线的可行性。认为该技术可大幅度降低脱硫废水的预处理成本,为脱硫废水预处理提供了可供参考的低成本技术方案。
This paper expounds the limitations of lime-soda softening process for desulphurization wastewater and analyzes technological features of brine purification by lime-flue gas method in salt production industry.The paper discusses the application of lime-mirabilite-flue gas process in desulphurization wastewater softening and theoretically demonstrates feasibility of the technical route. It is believe that the technique can drastically reduce the pretreatment cost of desulphurization wastewater,serving as a low-cost technical route of desulphurization wastewater pretreatment.
