摘要:

介绍了湿法脱硫废水的来源、水质特点及危害,系统分析了传统处理技术、浓缩减量化技术、固化技术、资源化利用技术等湿法脱硫废水处理技术的原理、研究及应用进展。对比不同湿法脱硫废水处理技术的优缺点,提出化学沉淀法工艺成熟、应用广泛,浓缩减量化技术、固化技术、资源化利用技术等深度处理技术可有效降低重金属含量、有机污染物含量,并回收部分有价组分,可满足废水零排放要求,但工艺普遍不成熟,大多处于实验室研究阶段。针对部分处理技术不成熟、经济效果不显著、工业应用缓慢等问题,认为前端减量、后端资源化处理是未来湿法脱硫废水处理技术发展的主要目标。

Abstract:

The source,water quality characteristics and hazards of wet desulfurization wastewater were introduced and the principles,research and application progress of wet desulfurization wastewater treatment technologies such as traditional treatment technology,concentration reduction technology,solidification technology,and resource utilization technology were systematically analyzed.Comparing the advantages and disadvantages of different wet desulfurization wastewater treatment technologies,it was proposed that the chemical precipitation method was mature and widely used,but the effluent had high salt content and heavy metal content and could not be reused,which was likely to cause secondary environmental pollution; advanced treatment technologies such as concentration reduction,solidification,and resource utilization could effectively reduce heavy metal content.organic pollutants,and recover some valuable components,which could meet the requirements of zero discharge of wastewater,but the process was generally immature,and most of them were in the laboratory research stage.In view of some problems such as immature treatment technology,insignificant economic effect and slow industrial application,it was believed that front-end reduction and back-end resource treatment were the main goals of future development of wet desulfurization wastewater treatment technology.

Key words: wet desulfurization, desulfurization wastewater, treatment technology, resource utilization
