摘要
燃煤电厂湿法烟气脱硫废水具有含盐量大、腐蚀性强、易结垢等特点,是制约电厂废水零排放的关键因素。从预处理、浓缩减量、末端处理三个方面详细介绍了脱硫废水的处理技术,分析各自的优劣,研究进展,并对烟道蒸发技术进行深入分析。最后通过工程实际案例,为燃煤电厂废水零排放提供了参考。
Coal-fired power plant of wet flue gas desulfurization wastewater with high content of salt,strong corrosiveness,easy fouling characteristics,is the key factor of restricting power plant wastewater zero emission. Desulfurization wastewater treatment technology was introduced in detail,based on the three aspects of pretreatment,concentration reduction,terminal treatments,and analyses their respective advantages and disadvantages,research progress,the flue evaporation technology was discussed in depth. Finally,this paper provide a reference for coal-fired power plant wastewater zero discharge through the practical engineering cases.
