摘要
通过采用生命周期评价方法,评估粉煤灰制备A型沸石的环境影响。粉煤灰制备A型沸石的18个环境影响类别中,人类致癌毒性影响最大,其次是淡水富营养化和化石资源短缺等,这些类别对环境的压力较大。粉煤灰制备A型沸石这一过程对人类健康影响最大,对资源影响最小。研究发现在粉煤灰制备A型沸石的过程中,电力能源的消耗对环境影响最为敏感,且火力发电是影响环境的主要因素。用水力发电、风力发电、核电、光伏发电都会降低环境影响潜能值。
This paper assessed the environmental impact of preparing A-type zeolite from fly ash through the Life Cycle Assessment(LCA)method.Among the 18 environmental impact categories of preparing A-type zeolite from coal ash,human carcinogenic toxicity has the greatest impact,followed by freshwater eutrophication and fossil resource scarcity,indicating that these categories exert significant pressure on the environment.The process of preparing A-type zeolite from fly ash has the greatest impact on human health and the least impact on resources.The study found that the consumption of electric energy is the most sensitive factor in the environmental impact during the process of preparing A-type zeolite from fly ash,and thermal power is the main factor affecting the environment in electricity.Using hydropower,wind power,nuclear power,and photovoltaic power can all reduce the potential value of environmental impact.
