Abstract： The wastewater discharge standard in China becomes more and more strict nowadays， achieves zero discharge of wastewater which brooks no delay. This paper introduces the water quality characteristics of desulfurization wastewater and three parts of zero discharge of desulfurization wastewater pretreatment， concentration， and evaporation solidification. In this paper， the principles and advantages and disadvantages of different technologies are compared and analyzed. This paper looks forward to the development of zero discharge technology of desulfurization wastewater in order to achieve zero discharge of desulfurization wastewater with high efficiency and economy.

Keywords： desulphurization wastewater; zero-emission; pretreatment; concentration; evaporation solidification

目前，大多數的燃煤电厂均采用石灰石-石膏湿法脱硫技术，该技术虽然具有脱硫效率高、系统运行稳定可靠等优点，但该技术产生了大量的脱硫废水[1]。（剩余5341字）
