摘　　要：通过分析工业固体废物管理过程与工业生产过程间的耦合关系,提出了涵盖减量化过程的工业固体废物生命周期管理框架和方法,并应用于铜渣管理的方案评估与决策过程中.结果表明,铜渣3种不同管理方案的环境负荷值依次为2800.46,2156.00,2162.04Pt.与熔池熔炼法相比,闪速熔炼法虽有利于铜渣的源头减量,但其减少的铜渣量并未导致精铜生产与铜渣管理全过程环境影响的整体下降.单从铜渣的内部再循环工艺来看,处理同样数量的铜渣,选矿法的环境表现优于电炉贫化法.案例研究证实了工业固体废物管理应将减量化过程纳入全生命周期管理方案中进行综合评估,而非简单遵循废物管理的优先顺序和等级制度.Based on analysis of the relationship between industrial solid waste management and industrial process,framework and method for life cycle management of industrial solid waste which integrate the source reduction process was presented.A case study of copper slag management was conducted with this method.The environmental burden of three scenarios for copper slag management was 2800.46 Pt,2156.00 Pt and 2162.04 Pt,respectively.Although Flash Smelting could promote reduction of copper slag compared with Bath Smelting,it did not relieve the gross environmental impacts in the whole life cycle of fine copper production and copper slag management.In consideration of slag closed-loop recycling process,environmental performance of Floatation Approach excelled that of Electric Furnace Impoverishment when treating the same quantity of copper slag.The case study proved that it is necessary to integrate the reduction process into the whole life cycle of industrial solid waste and make an integrated assessment of industrial solid waste management scheme,rather than to follow priority and hierarchy simply.
