“超低排放”下火电环境影响评价研究

Research on Environmental Impact Assessment of Coal-fired Power Plant under “Ultra-low Emission”

为了更好地贯彻落实国家有关电力行业的环保要求,地方政府、电力企业纷纷提出"超低排放"的建设或改造要求。"超低排放"使燃煤电厂污染物排放量大幅降低,对燃煤电厂环境影响评价工作提出了新的要求。通过选取2×1 000 MW、2×6 00 MW、2×350 MW 3种典型机组规模,东北、华北、华东、华南4个典型地域,80℃和46℃两种典型排烟工况,分析"超低排放"对燃煤电厂环境影响评价等级和范围的影响,对新形势下燃煤电厂环境影响评价工作提出建议。

In order to better implement the requirements of national environmental protection policy, local government and electric power industries have put forward the ＂ Ultra Low Emission＂ standards. ＂ Ultra-low emission＂ greatly reduced pollutants emission from coal-fired power plants, thus new considerations should be raised in environmental impact assessment for coal-fired power plant. This paper selects three typical unit scales （2 × 1 000 MW, 2×600 MW, 2 ×350 MW） in four typical regions （Northeast China, North China, East China, Southern China） with two typical smoke exhaust temperature （80℃ and 46℃ ） to analyze the impact of ultra low emission on the assessment grade and the scope of environmental impact assessment for coal-fired power plants. Suggestions are made for coal-fired power plant environmental impact assessment in current situations.
