含汞有害固体废弃物的固化/稳定化技术研究进展

Recent Advances in Stabilization/Solidification Technology for Treatment of Hg-containing Hazardous Wastes

总结了国外含汞有害固体废弃物固化技术的研究和应用发展现状。系统阐述了研究和应用较多的三种固化技术(水泥基、低温化学键磷酸盐陶瓷,硫聚合物)的固化过程原理、特征,研究和应用现状以及可得的操作数据。介绍了新兴的可能用于含汞固体废弃物的材料的研究数据。比较了各种技术的优缺点,应用上的局限性,为含汞固体废弃物的固化处理新技术的发展提供思路。

Stabilization and solidification technology for safe disposal of hazardous solid wastes, particularly mercury- contaminated wastes are briefly described in respect of the related researches and security assessment. Several studies completed in recent years are reviewed such as cement encapsulation, chemically--bonded phosphate--ceramics encapsulation and sulfur- polymer-stabilization/solidification with the relevant technical data. This paper also introduces some new materials which are under development and can be potentially used for the encapsulation of Hg containing wastes.
