| 摘 要： | 在污泥混合堆肥过程中,通过采用不同的填充料配比对污泥进行处理,分析该过程中重金属总量和DTPA提取的重金属含量变化。结果表明,通过污泥混合堆肥,重金属总含量不会降低,但重金属的生物有效性可以降低。

| Abstract: | During a composting of sewage sludge,we took several samples and analyzed them to reveal dynamics of the change of selected heavy metals including Zn,Cu,Pb,Cd,and Ni during the composting process.On the basis of related data obtained,we have discovered that the availability of the heavy metals was reducing steadily,but the total amounts of the heavy metals studied were kept at relatively constant. |
