摘　　要：黄水是固态法酿造白酒时存在于泥窖中的棕黄色黏稠液体。通过活性炭的吸附作用,不仅能有效的降低黄水的色度和化学需氧量(COD),而且在一定程度上能吸附不良气味。利用正交实验分析方法,得到活性炭最佳处理条件:3.5%(w/v)糖用活性炭在40℃下对黄水吸附20 min,最终黄水的脱色率可达67.47%(±0.24%),为后续有效成分的提取奠定了基础。Yellow water, the brown and sticky muddy liquid, is the by-product in the production of Baijiu by solid-state fermentation. Treating yellow water with active carbon could not only effectively reduce the color and COD of yellow water, but also absorb the off-odor. The best conditions for active carbon treatment were summed up by orthogonal test as follows： 20 min absorption by 3.5 % （w/v） active carbon at 40 ℃. As a result, the final decolorization rate of yellow water reached up to 67.47 % （±0.24 %）. This study has laid the foundation for subsequent extraction of efficient components from yellow water.
