污水淤渣中金属成份快速监测技术研究进展

Rapid Determination of Metal Ingredient in Sewage Sludges

当前，污水处理后的各种淤渣越来越多，如何最终处理这些淤渣已成为当代社会的又一课题，其中一个重要途径是施于农田等农业土壤作肥料。但是，如果污水淤渣中含有超标准的重金属元素，它将污染土壤。因此，有必要对此类淤渣进行分析测定。故要求建立快速、准确、简便的金属成份监测方法。本文综述和讨论了本领域的研究动态和发展趋势。

The sewage sludges are the solid materials remaining after the treatment of sewage.The sewage sludges can be used as amendments on crop land.However,some sewage sludges contain heavy metals which pollute soil.So it is necessary to determinate the metals in sewage sludges.This paper gaive a overview on the progresses and trends of determinating the metals in sewage sludges.The contents of the paper covered analytical methods,Sample preparation,metal speciation,future developments and so on.
