| 摘 要： | 对比研究了好氧污泥、厌氧污泥和厌氧颗粒污泥对染料活性黑KN-B的吸附和降解。结果表明,这3种污泥对活性黑的吸附均符合Freundlich模型(R~2为0.9665～0.9859)和Langmuir模型(R~2为0.9460～0.9906),但3种污泥对活性黑这种染料的吸附量较小;并且厌氧污泥对活性黑的吸附能力优于好氧污泥和厌氧颗粒污泥。实验还发现,3种污泥对活性黑的脱色主要是生物降解作用,而不是吸附作用。

| Abstract: | The adsorption and degradation of a dye, Reactive Black KN-B by three kinds of sludge including aerobic sludge, anaerobic sludge and anaerobic granular sludge were investigated, respectively. Results show that the adsorption of the dye by the three kinds of sludge fitted well both Freundlich model ( R~2 =0.9665 ～0.9859) and Langmuir model (R~2 =0. 9460～0.9906) , however, the adsorption amount of Reactive Black KN-B by these three sludge was low, and the adsorption capability of anaerobic sludge was better than aerobic sludge, anaerobic granular sludge. From the conclusion of experiments, it suggested that the decolorization of Reactive Black KN-B by sludge was mainly due to the sludge degradation rather than sludge adsorption. |
