摘要
本文主要是研究黄县褐煤净化含铬废水的条件、机理和效果。发现pH<3时,褐煤净化Cr(Ⅵ)的效果较好;pH>4时.净化Cr(Ⅲ)的效果较好。pH值较低时,褐煤对Cr(Ⅵ)的净化有吸附和还原作用。净化方法简易可行。
The conditions, mecnanism and effect of the treatment of chromium-containing waste with Huang-xian lignite were studied. The data showed that pH<3 was better for Cr(Ⅵ), while pH>4 for Cr(Ⅱ). At lower pH Cr(Ⅵ) was reduced and absorbed by lignite. This method was simple and feasible.
