摘　　要：偶氮染料废水由于其有机成分复杂、色度高、毒性强、难降解等而被视为急待处理的废水之一.生物锰氧化物由于其高催化活性而具有很大的控制水污染的潜力.本文研究Pseudomonas putida QYS-1产生的生物锰氧化物用于甲基橙和刚果红的脱色,对于相同初始浓度的甲基橙和刚果红,生物锰氧化物对其的脱色效果存在显著的差异,刚果红脱色率比甲基橙高59%.通过生物锰氧化物的循环利用,表明生物锰氧化物随着循环利用次数的增加,其自身活性及对偶氮染料的脱色作用显著降低.Azo dye wastewater is considered as one of the wastewater to be treated because of its complex organic components, high chroma, strong toxicity and difficult degradation. Bio-manganese oxides have great potential for controlling water pollution due to their high catalytic activity. In this paper, the biological manganese oxide produced by Pseudomonas putida QYS-1 was used to deeolorize methyl orange and congo red. For the same initial concentration of methyl orange and congo red, bio-manganese oxide had significant decoloration effects on it, Congo red decolorization rate 59% higher than methyl orange. Through the bio-manganese oxide recycling, bio-manganese oxide shows that its activity and decoloration of azo dyes are significantly reduced with the increase of recycling times.
