摘　　要：对西安市三家大的污水处理厂的污泥中重金属含量及浸出毒性进行测定,结果表明:污泥中重金属的总含量过高,其中最为严重的锌超过污泥农用标准的7.4倍;污泥中重金属的浸出率都很低,大部分在1‰以下。而且根据污泥中重金属的特点指出了污泥建材是一种可行的资源化利用方法。In this experiment, heavy metal concentration and heavy metal leaching-out toxicity in sludge which is from Xi＇ an three big sewage treatment plants are measured. The results indicate that, total concentration of heavy metal is excessively high, and the most serious element of Zn surpasses the sludge agricultural use standard 7.4 times;heavy metal leaching-out toxicity is excessively low ,most of which below 1/1 000. Further more, it is pointed that utilizing sludge for building materials is a feasible resourceful utilization method according to characteristics of heavy metal.
