燃煤电厂脱硫废水零排放技术现状与展望

Current situation and prospect of zero discharge technology for desulfurization wastewater from coal-fired power plants

近年来随着国家对于环保问题以及节能减排的重视,燃煤电厂脱硫废水零排放已势在必行。为燃煤电厂在选择脱硫废水零排放处理工艺时可以提供科学有效的参考,本文针对脱硫废水的主要特点及零排放技术现状,在国内外最近研究成果和燃煤电厂实际改造案例的基础上,对脱硫废水零排放技术的传统工艺路线进行归纳总结。通过对零排放技术的分析研究,总结出当前技术路线存在的问题,同时也为未来优化改进的研究发展方向提出建议。

In recent years,with the national attention to environmental protection and energy conservation and emission reduction,zero discharge of desulfurization wastewater from coal-fired power plants has become imperative.It can provide a scientific and effective reference for coal-fired power plants to choose zero discharge treatment process of desulfurization wastewater,this article in view of the main characteristics of the desulfurization wastewater zero discharge and technology present situation,the recent research results and coal-fired power plants at home and abroad,on the basis of real cases,the traditional process of desulfurization wastewater zero emissions technology route of generalizations.Through the analysis and research of zero-emission technology,the existing problems of current technology route are summarized,and suggestions for future research and development direction of optimization and improvement are put forward.
