本文研究了沸石及膨润土对水泥-铬渣体系中Cr(Ⅵ)浸出的影响。结果表明:沸石和膨润土对Cr(Ⅵ)的浸出有较好的效果,在pH=3,掺量为30%的条件下,28d龄期掺入沸石和膨润土的硬化体中Cr(Ⅵ)浸出浓度分别下降了82%及63%,沸石的效果优于膨润土。雨淋的自然养护条件会导致体系中Cr(Ⅵ)的浸出浓度减少近一倍。同时,硬化体抗压强度随着掺量的增加而下降,膨润土对强度的不利影响大于沸石。 In this paper, the effects of zeolite and bentonite on Cr (Ⅵ) leaching in cement-chromium slag system were studied. The results show that zeolite and bentonite have good effect on the leaching of Cr (Ⅵ). Cr (Ⅵ) leaching was achieved in 28d - age hardened composites doped with zeolite and bentonite at pH = 3 and 30% Concentration decreased by 82% and 63%, respectively, zeolite better than bentonite. Natural conditions of rain will lead to the system of Cr (VI) leaching concentration nearly doubled. At the same time, the compressive strength of hardened composites decreased with the increase of the content, and bentonite had greater negative effect on the strength than zeolite.
