摘　　要：铅基固废是含铅的固体废物,主要来源于锌、铅、铜冶炼过程和废旧铅酸蓄电池回收,含有大量有价金属,同时对环境有一定的污染,因此摸清铅基固废的来源结构、产量及区域分布显得尤为重要。本文在实地企业调研的基础上分析了锌、铅、铜主要冶炼技术及其产生的铅基固废,根据单吨精炼金属的固废产出比及精炼金属产量测算了铅基固废产量,基于锌、铅、铜产量分布描绘铅基固废的区域分布,依照铅基固废污染元素含量和铅基固废产量测算有价元素的产量,以期为铅基固废处置技术开发研究及产业布局提供基础支撑。Lead-based solid waste mainly comes from zinc,lead and copper smelting process and waste lead-acid battery recycling system.It contains a large number of valuable metals and pollutes the environment.Therefore,it is particularly important to find out the source structure,output and regional distribution of lead-based solid waste.Based on the field investigation of enterprises,this paper analyzed the main smelting technologies of zinc,lead and copper and their production of lead-based solid waste.According to the output solid waste ratio of single ton refined metal and the output of refined metal,the output of lead-based solid waste was calculated.Based on the distribution of zinc,lead and copper smelting output,the regional distribution of lead-based solid waste was described.According to the content of lead-based solid waste pollution elements and the output of lead-based solid waste,the output of valuable elements was calculated,in order to provide basic support for the development research and industrial layout of lead-based solid waste disposal technology.
