摘要
针对燃煤烟气脱硫废水中硒污染物的产生、潜在危害、迁移转化路径及处理技术等方面开展了详细讨论,总结了膜分离技术、零价铁技术、离子交换技术、多孔吸附技术及生物还原技术在硒污染物脱除领域的研究现状,提出开发适应特殊高浓度硫酸盐水环境的新型吸附技术是未来脱硫废水中硒污染物控制的研究方向。
The generation,potential hazards,migration and transformation pathways,and treatment technologies of selenium pollutants in coal-fired flue gas desulfurization wastewater are discussed in detail.Current research status on the technologies for removing selenium pollutants are summarized,including membrane separation,zero valent iron,ion exchange,porous adsorption,and biological reduction technologies.It is proposed to develop new adsorption technology adapted to the special high concentration sulfate environment,which will be the research direction for selenium pollution control in desulfurization wastewater in the future.
