| 摘 要： | 污泥堆肥化后的土地利用是污泥处理处置的重要方法之一。经过对荆马河底泥接种堆置处理，揭示出污泥中重金属的形态发生明显的变化。荆马河底泥中的重金属污染物主要以结合态和残渣态的形式存在，水溶态和交换态的量很小，经接种堆置处理后，水溶态和交换态量大幅削减，结合态和残渣态量有所增加，总量变化不大，生物学方法和化学方法测定都表明，处理后的底泥生物毒性有明显降低，重金属的生物有效性降低。

| Abstract: | The land utilization through the compost disposal of sludge is one of important ways to the sludge treatment in cities. The disposal of inoculated accumulation for the sludge in the bottom of the Jinma River in Xuzhou City shows that the forms of heavy metals in sludge have been changed obviously. The heavy metals with different forms have different biological effectiveness. In general, the biological effectiveness of heavy metals with water soluble and exchangeable forms is higher and that with bound and residue forms in much lower than other metals. The bound and residue forms are the majou existence form of heavy metal contaminant in the bottom of Jinma River. The quantity of the heavy metals with water soluble and exchangeable forms is very small. After the inoculated accumulation ,the quantity of water soluble and exchangeable forms is decreased substantially and the one of bound and residue forms is increased. The biological effectiveness of heavy metals is also decreased sometimes. The measurement of biological and chemical methods indicates that the biotoxicity of treated sludge in the bottom is obviously decreased. |
