基于生命周期评价方法,采用GaBi软件提供的CML2001方法对1t球团产品进行生命周期评价,分析球团工艺中的原料、 能源消耗以及环境排放,包括选取环境影响评价指标,分类化特征化.分析结果表明,酸化是球团工艺对环境影响的主要类型,占总环境影响潜值的36.95%,环境影响由大到小分别为酸化(AP)、 温室效应(GWP)、 人体健康潜力(HTP)、 光化学毒性(POCP)、 富营养化潜力(EP)和臭氧层耗竭潜力(ODP).研究为钢铁产品的生态设计和开发提供了方法.%Based on the methodology of life cycle assessment , using GaBi to analyze the material and energy consumption and environmental emissions during production of 1t sinter, and CML2001 method provided by GaBi was used to perform environmental impact assessment of pelletizing process.inclu-ding selection of impact category , selection of characterization model and explanation of characteriza-tion result. The results indicate that the AP is the main environmental impact in the pelletizing process , which accounts for 36.95%of the total environmental impact potential.Regarding the extent of environmental impacts , these factors tank as AP , GWP, HTP, POCP, EP and ODP.The re-search presented the method on the eco -design and development for the iron and steel products.
