摘要 燃煤电厂作为电力主要的生产方式,其大气污染物控制是中国关注的重点。为满足日益严格的要求,我国对燃煤电厂大气污染物排放标准已进行了多次修订。尤其是在2015年,多部门联合发布《全面实施燃煤电厂超低排放和节能改造工作方案》,期望到2020年全部具备改造条件的燃煤电厂均实现超低排放。中国正处于“超低排放”收尾阶段和下一步计划“近零排放”的开始阶段。尽管我国燃煤电厂大气污染物的排放限值在国际上处于相对领先的水平,但与欧美国家相比,相关排放标准仍然存在一些不足。在此背景下,通过多视角对比分析我国燃煤电厂与国外欧美国家燃煤电厂排放标准差异,分别从执行对象、达标评判方法、分析检测方法和经济效益等多方位提出进一步优化我国燃煤电厂大气污染物排放标准的相关建议,以便更好地实施近零排放。 As the main form of coal used for electricity, the control of air pollutants from coal-fired power plants has always been the focus of China. To meet increasingly stringent requirements, the air pollutant emission standards for coal-fired power plants in China have been revised several times. In 2015, the “Work Plan for Comprehensive Implementation of Ultra-Low Emissions and Energy-saving Retrofits for Coal-fired Power Plants” was issued, and it is expected that by 2020, all coal-fired power plants that are eligible for transformation will achieve ultra-low emissions. At this stage, the control of air pollutants from coal-fired power plants in China is at the end of “ultra-low emissions” and the beginning of “near-zero emissions”. Although the emission standards of coal-fired power plants in my country are already at the international leading of coal-fired power plants in my country. In this context, multi perspective comparative analysis was conducted between coal-fired power plants of China and abroad in Europe and the united national standards level. Related suggestions of further optimization of the emission standard of Chinese coal-fired power plants were proposed in terms of implementation objects, evaluation methods for meeting standards, analysis and detection methods, and economic benefits, which can help to better implement near-zero emissions.
