| 摘 要： | 以实验室模拟试验探讨含Cr~(6+)的铬渣与生活垃圾、建筑弃料混合堆置时,Cr~(6+)的迁移转化规律。试验结果表明,铬渣与生活垃圾或建筑弃料进行混合堆置时,生活垃圾和建筑弃料均具有截留Cr~(6+)的能力。而生活垃圾的截留能力强于建筑弃料;生活垃圾等废弃物对Cr~(6+)还原、吸附后,转化为难以再溶出的结合态铬,吸附态铬所占比例<1.0％。

| Abstract: | From laboratory simulation test, this paper discussed themoving and transforming rule of Cr~(6+) in the process of co- disposal of chromium slag and domestic garbage etc. Theresult showed that domestic garbage and construction refusehave a intercepting ability to chromium, and the interceptingability of domestic garbage was greater than that of con-struction refuse. Cr~(6+) will be reduced and adsorbed at first,and than transformed to a combined state which was inso-luble in the leachate. |
