摘要
水泥行业是我国重要的基础原材料行业之一,其广泛地应用于建筑、国防、道路等领域。随着可持续发展的不断推进,我国水泥行业正处于从高能耗、高污染的集约型生产向环境友好型发展模式的转型时期。基于生命周期评价方法,建立了适用于水泥生产流程的环境影响评价指标体系和方法步骤,介绍了据此开展的新型干法水泥生产流程环境负荷热点辨识和工艺优化效果评价研究,进一步定量评价并比较了水泥窑协同处置污泥、生活垃圾以及工业废物替代原料的技术方案,为实现水泥生产流程环境负荷的科学定量与低环境负荷利废水泥的生态设计与应用提供方法与数据支撑。
As one of the important basic raw material industries in China, cement is widely used in construction, national defense, roads and other fields. Along with the continuous progress of the sustainable development, cement industry is under the change stage from the intensive production of high energy consumption and high pollution to the environment friendly development mode. In this study, an environmental impact assessment index system and procedures based on Life Cycle Assessment method were established, which suit for cement production process. The research of environmental impact hotspot identification and process optimization effect evaluation on the new dry cement production process was introduced. Moreover, quantitative evaluation and comparison for technology solutions of the cement kiln co-disposal of sludge and house- hold garbage, as well as industrial waste in place of raw materials were carried out in order to provide guidance for accurate quantification of environmental burden in cement production process and eco-design of environment friendly waste-based cement.
