中文摘要: |
研究了醌基聚氨酯泡沫强化活性污泥厌氧处理偶氮染料活性艳红X\|3B的特性.实验结果表明:不同污泥浓度、电子供体和温度对活性艳红X\|3B厌氧生物脱色具有不同程度的影响;在污泥浓度1.8 g·L-1,电子供体甲酸钠浓度1.5 g·L-1,温度30 ℃条件下,醌基聚氨酯泡沫连续使用10次,其介导的活性艳红X\|3B脱色率一直能够保持在90%以上,且其在连续30 d强化活性艳红X\|3B脱色过程中起到了很好的催化作用;与无醌体系相比,活性污泥厌氧处理活性艳红X\|3B的启动期明显缩短了. |
英文摘要: |
The accelerating effect of anthraquinone-2-sulfonate (AQS) immobilized in polyurethane foam (PUF) on anaerobic bio-decolorization of azo dye Reactive Brilliant Red X-3B by activated sludge is investigated. The experimental results show that the sludge concentration, electron donors and temperature have different effects on AQS-PUF mediated bio-decolorization of Reactive Brilliant Red X-3B. After 10 repeated experiments using AQS\|PUF under the anaerobic conditions (30 ℃, 1.8 g·L-1 sludge and 1.5 g·L-1 sodium formate), immobilized AQS-mediated bio-decolorization efficiency of Reactive Brilliant Red X-3B retains 90% of their original value. The decolorization efficiencies of Reactive Brilliant Red X-3B are obviously enhanced using AQS-PUF during 30 days running. Compared with the lacking immobilized AQS, the start-up time of bio-decolorization of Reactive Brilliant Red X-3B is significantly shortened using AQS-PUF under anaerobic conditions. |
