对城市污水处理厂污泥中重金属来源、危害及处置进行讨论。采用火焰原子吸收法及原子荧光法对某城市污水处理厂污泥中重金属进行测定，结果表明： Zn、 Pb、 Cr、 Hg含量均符合我国《城镇污水处理厂污染物排放标准》污泥农用控制标准， Cd、 Cu含量略高于该标准；依据重金属元素在污泥中的主要存在形态，讨论了污泥排放对环境的潜在风险；提出固定或沥滤处理可用于污泥处置，固定处理法相对经济，操作简便，更易推广。

Discussed the source, harm and treatment of heavy metals in sewage sludge. The sludge samples were collected from a wastewater treatment plant, in which the contents of heavy metals were analyzed using Atomic Absorption Spectrometry and Atomic Fluorescence Spectrome-try method. The results showed that the contents of Zn, Pb, Cr, and Hg were below the standard values of sludge used for agriculture in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. The content of Cd, Cu were a little hjgher than the above standard. According to the contents and main speciation of heavy metals in sludge, the potential risk of discharging sludge to the environment was discussed. The measures of immobilization and leaching can be selected to treat the sludge, while the immobilization is more economic, and simple to be operated and popularized.
