水泥工业生产过程重金属的管控

Control of heavy metals in production process of cement industry

介绍了水泥工业产品中重金属含量限值、水泥生产过程中的重金属来源分析、水泥生产企业重金属排查工作方法、协同处置生活垃圾对水泥产品质量的影响分析等,重金属排查结果可看出,水泥熟料中重金属控制主要方向是水泥生产的常规铁铝质矫正料,协同处置生活垃圾后,水泥熟料、水泥产品的浸出特性不会发生显著性改变。

This paper introduces the content limit of heavy metals in cement industrial products,the source analysis of heavy metals in the cement production process,the working method of heavy metal inspection in cement production enterprises,the analysis of the impact of co-processing domestic waste on the quality of cement products,etc.The results of heavy metal inspection can be seen,The main direction of heavy metal control in cement clinker is the conventional iron-aluminum correction material for cement production.After co-processing domestic waste,the leaching characteristics of cement clinker and cement products will not change significantly.
