研究了上流式厌氧污泥床（UASB）反应器在不同运行条件下对真实的纺织废水（RTW）的脱色和COD去除效果。UASB反应器对COD的去除率可达90%以上。超过92%的颜色去除由于生物降解实现。厌氧颗粒污泥在处理纺织废水过程中，其活性不受影响。在纺织废水处理中，球形细菌是甲烷丝菌类细菌的优势菌群。出水碱度、挥发性脂肪酸（VFA）含量和pH值表明，纺织废水对厌氧过程没有抑制作用。结果表明，UASB反应器系统可有效地用于纺织废水的脱色和COD的去除。(C)2007爱思唯尔有限公司保留所有权利。
The upflow anaerobic sludge blanket (UASB) reactor was evaluated for its efficacy in decolourization and reduction in chemical oxygen demand (COD) of real textile wastewater (RTW) under different operational conditions. The efficiency of UASB reactor in reducing COD was found to be over 90%. Over 92% of colour removal due to biodegradation was achieved. The activities of the anaerobic granules were not affected during the treatment of textile wastewater. Cocci-shaped bacteria were the dominant group over Methanothrix like bacteria in textile wastewater treatment. Alkalinity, volatile fatty acids (VFA) content and pH in effluents indicated that the anaerobic process was not inhibited by textile wastewater. It is concluded that UASB reactor system can effectively be used in the treatment of textile wastewater for the removal of colour and in the reduction of COD. (C) 2007 Elsevier Ltd.
