【摘要】 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。更多还原

【Abstract】 Stabilization and solidification technology for safe disposal of hazardous solid wastes,particularly mercurycontaminated 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 sulfurpolymer-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.更多还原
