摘　　要：当前存在大量的固体废物得不到妥善处理,而利用固体废物来烧结陶粒符合可持续发展理念,是一种可行的资源化方式。本文首先阐述了三种典型固废烧结陶粒工艺过程的差异以及烧结过程中的一些关键工艺;其次,分析了产品陶粒中七种重金属Cr、Zn、Cu、Cd、Ni、Pb和As在上述烧结过程中的固定与挥发过程,并总结了可能影响这一过程的六种因素;最后,总结了陶粒产品在混凝土、水处理、吸声材料和陶粒支撑剂等四个主要领域以及其他新兴方向的研究和应用现状,并提出了当前陶粒重金属迁移固化以及陶粒研究应用存在的一些问题和展望,为固废烧结制备陶粒过程及后续陶粒产品使用中的重金属污染防控提供参考。At present,there are still a lot of solid wastes that can’t be properly treated,and using solid wastes to sinter ceramsite not only conforms to the concept of sustainable development,but also can turn waste into treasure,which is a feasible way of resource utilization.Firstly,the differences of three typical processes for sintering ceramsite from solid waste and some key processes in the sintering process were expounded.And then,the solidification and volatilization processes of seven heavy metals Cr,Zn,Cu,Cd,Ni,Pb and As in the product ceramsite during the sintering process of the above solid waste were analyzed,and six factors that may affect this process were summarized.Finally,the research and application status of ceramsite products in four main fields,such as concrete,water treatment,sound absorption materials and ceramsite proppants,and other emerging directions were summarized.Besides,some problems and prospects in the current migration and solidification of ceramsite heavy metals and the research and application of ceramsite were put forward,which can provide reference for the prevention and control of heavy metal pollution in the process of sintering ceramsite from solid waste and the subsequent use of the ceramsite products.
