【摘要】 燃煤电厂运行中产生的烟气含有大量硫氧化物，直接排放会严重污染环境，因此，需要对烟气进行脱硫处理，减少对空气的污染。目前，在燃煤电厂常用的湿式石灰石-石膏法烟气脱硫工艺中，会附带产生大量的脱硫石膏副产品。在当前节能减排和资源再利用的背景下，对脱硫石膏的产生进行了论述，并对比了天然石膏与脱硫石膏的差异，在此基础上，探讨了脱硫石膏多种综合利用的途径。更多还原

【Abstract】 The flue gas produced in the operation of coal-fired power plants contains a large amount of sulfur oxides,which will seriously pollute the environment.Therefore,it is necessary to desulfurize the flue gas to reduce air pollution.At present,in the wet limestone gypsum flue gas desulfurization process commonly used in coal-fired power plants,a large number of desulfurization gypsum by-products will be produced.Under the background of energy conservation,emission reduction and resource reuse,this paper discusses the production of desulfurization gypsum,compares the differences between natural gypsum and desulfurization gypsum,and discusses various ways of comprehensive utilization of desulfurization gypsum.更多还原
