以燃煤电力行业为例，在确定石灰石－石膏湿法烟气脱硫技术分析对象和范围的基础上，进行排放清单分析，并评价其对环境的影响。结果表明，从生命周期全过程来看，石灰石－石膏湿法烟气脱硫存在粉尘、噪音和生态破坏等环境问题；且其生态恢复成本及脱硫石膏和脱硫废水的无害化处理成本远高于目前所估算的烟气脱硫成本。根据我国目前的能源结构和环境现状，石灰石－石膏湿法烟气脱硫技术不具有可持续性，而烟气循环与梯度利用技术是值得示范和推广的烟气净化技术。

With a case study of coal fired power plants, and based on the definition of goal and scope, the emission inventory analysis and environment impact evaluation were performed for limestone-gypsum wet flue gas desulphurization ( WFGD ) technology.From the viewpoint of the whole life cycle, there exist environmental problems in limestone-gypsum WFGD, including dust, noise and ecological destruction, etc.The ecological restoration cost and the cost for harmless treatment of desulphurization gypsum and desulphurization wastewater are far higher than the FGD cost currently evaluated.Considering China′s current energy structure and environmental status, the limestone-gypsum FGD technology is not sustainable, and the flue gas recycling technology with cascade utilization should be worthy of demonstration and dissemination.
