摘要

研究了厌氧膨胀颗粒污泥床(EGSB)反应器中颗粒污泥对11种染料的脱色效果。经过7天的培养，首次观察到活性红21、23、180和活性黄15、17、23在模型纺织废水中的生物脱色效果(脱色率超过94%)。根据对EGSB颗粒污泥16S rRNA基因扩增子的测序分析，与丙酸古杆菌相关的操作分类单元在染料存在时的相对丰度比在没有染料的情况下增加最多(平均为7.12倍)。

Evaluation of dye decolorization using anaerobic granular sludge from an expanded granular sludge bed based on spectrometric and microbiome analyses.

The decolorization of 11 dyes by granular sludge from an anaerobic expanded granular sludge bed (EGSB) reactor was evaluated. Biological decolorization of Reactive Red 21, 23, and 180, and Reactive Yellow 15, 17, and 23 in model textile wastewater was observed for the first time after a 7-day incubation (over 94% decolorization). According to the sequencing analysis of 16S rRNA gene amplicons from EGSB granular sludge, the operational taxonomic unit related to Paludibacter propionicigenes showed the highest increase in relative abundance ratios in the presence of dyes (7.12 times on average over 11 dyes) compared to those without dyes.
