| 摘 要： | 采用穿透渗漏和常见的环绕流动渗漏（动态渗漏）实验方法，研究和比较了经水泥固化的稳定化／固化有毒有害废物的渗漏行为，所用的合成重废物样吕由Ｐｂ＾２＋、Ｚｎ＾２＋、Ｃｕ＾２＋、Ｎｉ＾２＋和Ｃｒ（ＶＩ）等５种重金属组成，结果表明，在同种渗漏方式中，重金属的渗漏行为不同。发生穿透渗漏时，重金属的渗漏速率较环绕流动渗漏时高。由于穿透渗漏加束渗漏过程，因此用它研究废物渗漏行为可节省实验时间。

| Abstract: | s:Both the flow through leaching and the more common flow around(dynamic leaching)test methods were carried out to compare the leaching behavior of the cement based stabilized/solidified waste.The solidified waste samples were prepared from five kinds of heavy metals with two kinds of binders.The metals were Pb 2 ,Zn 2 ,Cu 2 ,Ni 2 and Cr(VI).The results showed that the leaching behavior of heavy metals was very different under two kinds of leaching pattern.The leaching rate of heavy metals was higher in flow through leaching than that in flow around leaching.Because the flow through leaching method could hasten the leaching process so the experiment period could be shorten by this method. |
