摘　　要：结合石灰石法(又称石灰石—石膏法)烟气脱硫的技术特点,分析了石灰石粉尘、二氧化碳、硫石膏废渣、脱硫污水和酸雨等5种潜在的环保风险,指出其最大的环保风险是将废气变成废渣,治标不治本,不符合低碳环保和循环经济的发展战略,并提出了相应的风险控制措施和彻底化解环保风险的对策建议。For the technical features of limestone process( also known as limestone-gypsum process) flue gas desulfurization,5 types of potential environmental risks involving limestone dust,carbon dioxide,sulfur gypsum slag,desulfurized waste water and acidic water are analyzed,and the biggest environmental risk is to turn the waste gas into waste slag,which is superfacial,and can't meet the development strategy of low-carbon and cyclic economy,and relevant risk control measures and recommended countermeasures to mitigate the environmental risks are proposed.
