污染水体底泥中重金属的处理技术研究进展

Research Progress of the Treatment Technology on Heavy Metal-contaminated Water Sediments

针对河湖泊涌等水体底泥重金属污染问题,介绍了我国水体底泥的重金属污染现状及其来源,分析了近年来国内外污染底泥中重金属处理技术的原理及其应用现状,主要包括底泥重金属稳定化技术和底泥重金属去除方法。总结了底泥重金属处理技术的优缺点,期望能为今后底泥重金属处理技术的研究提供参考。

More and more attention was paid on the pollution of rivers and lakes sediments,particularly the heavy metal pollution.The principles and application status of heavy metal contamination of sediment was presented,and the treatment methods of heavy metal pollution from domestic and abroad in recent years was summarized including the stabilization and removal technology of heavy metal.Lastly,their advantages and disadvantages of these technologies were compared,which was desirable to provide a theoretical basis for the processing of heavy metal in sediments.
