摘　　要：对比研究了双氧水工艺和双氧水-活性炭联合工艺对天津某污水厂二级出水色度的降解效果。结果表明,后者对色度能产生良好的协同去除效果;分子质量分布实验结果表明有色溶解性有机物(CDOM)对色度起到重要贡献,二级出水色度主要分布在表观分子质量>100 ku和<1 ku范围;双氧水将大分子的有色腐殖质降解为小分子有机物,而活性炭对有色的含苯环有机物去除效果明显。The degradation effects of chroma by single process of hydrogen peroxide and combined hydrogen peroxi- de-activated carbon process have been compared. The results show that hydrogen peroxide-activated carbon process has better collaborative removing effect. Molecular mass distribution results show that colored dissolved organic matter（CDOM） has important contribution to chroma. The chroma of secondary effluent are mainly distributed in the range of apparent molecular weight greater than 100 ku and less than 1 ku. Hydrogen peroxide can degrade the macromolecules of colored humus mass into small molecular organics, and activated carbon has significant removing effect on colored benzene ring containing organics.
