摘要
以工业废料、废渣、下水道污泥等废物为原料制造的生态水泥,Pb2+、Zn2+是其中所含的主要微量重金属元素。通过模拟德国的水槽试验法对水泥混凝土中Pb2+、Zn2+的浸出情况进行测试。测试结果表明,Pb2+、Zn2+可以很好地固化在混凝土中,不会对环境造成二次污染。
The Pb^2＋ and Zn^2＋ were main heavy metals in the cement which was doped with industrial waste residue and sewage sludge. The leaching mechanism and ability of Pb^2＋ and Zn^2＋ were tested by simulation of the trough experiment of Germany. The result show that Pb^2＋ ,Zn^2＋ can be solidified well by concrete. So Pb^2＋ ,Zn^2＋ had no secondary pollution to the environment.
