The Research of Solidification/Stabilization of Contaminated Sediments by Heavy Metal
摘要: 河道中底泥污染物主要以重金属和有机物污染为主。文章主要对重金属污染的底泥及其固定化稳定化处理的机理进行了文献回顾。首先总结了底泥的物理化学性质，及其污染物的特征、污染现状；其次阐述了水泥、石灰、粉煤灰等固化剂在S/S中发生的水化反应，讨论了底泥、污染物和固化剂三者之间的相互作作用，并指出了固化/稳定化修复技术存在的不足；在文章中，研究人员跟据前人经验和理论，对底泥处理制定了S/S决策性管理流程，并对后期的维护与监测进行了简单的介绍；在文章最后对研发高效、绿色、低成本、效果持久的处理方法进行了展望，以及对处理底泥节约成本方面提出了建议。
Abstract: The mechanism of heavy metal contaminated sediment and its treatment method of solidification and stabilization (the following is abbreviated as S/S) were reviewed in this paper. At first, the physical and chemical properties, characteristics and pollutants of sediment are described. Next, the interaction of cement, lime, fly ash and other binders are termed as hydration reaction, and the interaction effect among sediments, pollutants and binders are discussed. Then the disadvantage of solidification/stabilization technology is accused in this paper. The author has made design of S/S technology on the basis of previous experience and the theory of sediment remediation. Main-tenance and monitoring of the later are introduced. In the end, efficient, green, low cost, lasting ef-fect methods are discussed, and the cost-saving suggestions of sediment treatment are put forward.
