摘要
针对目前燃煤电厂废水零排放工作的3种主流技术,分析各种技术的优点、缺点、适应性。提出目前燃煤电厂脱硫废水零排放采用烟气余热浓缩+结晶盐的技术,可以发挥主流技术独有的优势,规避其缺点,提纯出高纯度的NaCl结晶盐,实现燃煤电厂废水零排放。
The advantages,disadvantages and adaptability of three mainstream technologies of the zero discharge of wastewater from coal-fired power plants are analyzed.The technology of flue gas waste heat concentration+crystalline salt is recommended for zero-emissions of desulfurization wastewater,which can make full use of the unique advantages of mainstream technology,avoid its shortcomings,and purify high-purity NaCl crystalline salt to achieve zero discharge of coal-fired power plant wastewater.
