烟气脱硫石膏是燃煤电厂烟气脱硫后产生的固态残渣,其年产量大且综合利用率低。文章着重介绍脱硫石膏在污水处理、二氧化碳的固定、制备硫酸钙晶须以及土壤改良的研究现状,并阐述在环境治理中的不足,以拓宽脱硫石膏的应用领域,提高利用率,实现较高的社会效益、经济效益和环境效益。Flue gas desulfurization gypsum (FGDG) is a solid residue produced after flue gas desulphurisation in coal-fired power plants, with a large annual output and low comprehensive utilization rate. This paper highlights the current research status of FGDG in wastewater treatment, carbon dioxide fixation, preparation of calcium sulfate whiskers, and soil improvement, and elaborates on the deficiencies in environmental management, in order to broaden the application fields of FGDG, improve the utilization rate, and realize higher social, economic and environmental benefits.
