摘　　要：为了进一步提升城市污水处理效果,以某城市污水处理厂为例,对污水处理厂污泥重金属污染源进行了分析。首先,对某城市污水处理厂进行了简单介绍,并设计出了相应的试验方案,然后以此为基础,分别对基于潜在生态风险评价法的污泥重金属污染特征及污泥重金属污染源特征进行了分析。通过分析可知,由于该污水处理厂主要负责处理电镀、机械加工、有色金属冶炼等企业产生的废水,使得处理后的污泥中包含Cd、Cr、Pb、As、Hg、Ni、Cu、Zn等多种重金属元素,其中,Hg、Cd与Cu对周边环境的危害较大,应作为重点治理内容。In order to further improve the effectiveness of urban sewage treatment,taking a sewage treatment plant in a certain city as an example,the sources of heavy metal pollution in the sludge of the sewage treatment plant were analyzed.Firstly,a brief introduction was given to a sewage treatment plant in a certain city,and a corresponding experimental plan was designed.Based on this,the characteristics of heavy metal pollution in sludge and the characteristics of heavy metal pollution sources in sludge based on potential ecological risk assessment method were analyzed.Through analysis,it can be concluded that due to the fact that the sewage treatment plant is mainly responsible for treating wastewater generated by electroplating,mechanical processing,non-ferrous metal smelting and other enterprises,the treated sludge contains various heavy metal elements such as Cd,Cr,Pb,As,Hg,Ni,Cu,Zn,etc.Among them,Hg,Cd and Cu pose a greater threat to the surrounding environment and should be the focus of treatment.
