燃煤电厂脱硫废水零排放技术研究

Research on Zero Emission Technology of Desulfurization Wastewater from Coal-fired Power Plant

近年来,随着社会经济的快速发展,在燃煤电厂发展中,脱硫废水零排放工艺备受关注。脱硫废水经过浓缩后,通过蒸发结晶或烟道喷雾处理,降低其污染物排放量,减小对环境造成的污染。蒸发结晶可对水资源进行回收,但能耗比较高;烟道喷雾处理工艺操作方便,运行成本不高,但水资源却无法回收。实际操作中要根据具体情况合理选用处理技术。基于此,文章主要论述了燃煤电厂脱硫废水零排放相关技术,希望对相关领域研究有参考价值。

In recent years,with the rapid development of social economy,the zero emission technology of desulfurized wastewater has attracted much attention in the development of coal-fired power plants.The desulfurized wastewater is concentrated and evaporated or treated with flue gas spray to reduce the pollutant discharge and reduce the pollution caused by the environment.The water resources can be recovered by evaporation crystallization,but the energy consumption is high;the flue gas spray treatment process is easy to operate and the operation cost is not high,but the water resources can not be recovered.In actual operation,the treatment technology should be selected rationally according to the specific conditions.Based on this,this paper mainly discusses the related technologies of zero discharge technology of desulfurized wastewater from coal-fired power plants,hoping to have reference value for related research.
