摘　　要：烧结陶粒作为工业固体废物资源化利用的重要途径,不仅在重金属固化方面具有显著优势,还能减少对黏土和页岩等不可再生资源的消耗,是一种极具潜力的固废资源化与无害化的利用方式。本文系统综述了重金属的固化机理、固化效果(固化效率通常超过80%)、陶粒应用及影响重金属固化效果和陶粒产品性能(体积密度、机械强度和吸水率)的因素,并提出了当前固废基陶粒研究中的问题与未来可能的研究趋势,旨在为进一步提高高温烧结固废基陶粒的重金属固化效果及陶粒产品性能提供科学依据。As an important approach of resource utilization of industrial solid waste,sintered ceramsite not only has significant advantages in the heavy metal solidification,but also reduces the consumption of non-renewable resources such as clay and shale,making it a highly promising method for the resource utilization and harmless utilization of solid waste.In this paper,the solidification mechanism of heavy metals,the solidification effect(the solidification efficiency usually exceeds 80%),the application of ceramsite and the factors affecting the solidification effect of heavy metals and the product performance of ceramsite(bulk density,mechanical strength and water absorption)are systematically reviewed.Moreover,the current problems in the research of solid waste-based ceramsites and the possible research trends in the future are proposed,aiming to provide a scientific foundation for further improving the solidification efficiency of heavy metals and the ceramsite product performance of ceramsite sintered at high temperature.
