城市污水处理厂污泥中重金属污染治理方法研究进展

The Research Progress of Treatment Methods of Heavy Metal Pollution in Sludge of Municipal Sewage Treatment Plant

城市污水处理厂污泥含有大量的重金属物质,直接影响污泥资源化利用。所以,怎样全面处理污泥中的重金属物质,是当前污水处理厂重点思考的问题。通过分析我国污泥重金属含量情况可知,采用电动力学修复技术、生物沥滤法等,能够有效去除污泥中的重金属物质。本文分析了污泥中重金属处理处置现状,重点探讨城市污水处理厂污泥中重金属污染治理方法。

The sludge of municipal sewage treatment plants contains a large amount of heavy metals,which directly affects the resource utilization of sludge.Therefore,how to comprehensively treat the heavy metal substances in the sludge is the key consideration of the current sewage treatment plant.By analyzing the heavy metal content of sludge in China,it can be known that the use of electrodynamic remediation technology,biological leaching method,etc.can effectively remove heavy metal substances in sludge.This paper analyzes the status quo of heavy metal treatment and disposal in sludge,and focuses on the treatment of heavy metal pollution in the sludge of municipal sewage treatment plants.
