摘要: 实验研究了活性艳兰KN-G在好氧污泥上的吸附等温线和吸附动力学，考察了pH对好氧污泥吸附活性艳兰KN-G的影响。结果表明，好氧污泥对活性艳兰KN-G的吸附Freundlich和Langmuir方程准确性较高，但是从模型的准确性和稳定性两方面考虑，Freundlich方程更适合描述好氧污泥吸附活性艳兰KN-G。应用伪一级、伪二级反应动力学和颗粒内扩散方程模型对实验数据进行验证，表明好氧污泥吸附活性艳兰KN-G更符合伪二级反应动力学模型。 pH值对活性艳兰KN-G的吸附影响很大，pH值与吸附量呈负相关。

Abstract: Reactive turquoise blue KN-G (RTB) adsorption on aerobic sludge (AS) was studied through tests. It was found that the adsorption isotherm of RTB on AS satisfied both Langmuir and Freundlich models, while an evaluation on both accuratity and stability indicates that the Freundlich equation was the best. The adsorption of RTB on AS was analyzed using pseudo first-order, pseudo second-order adsorption and intrapartical diffusion kinetic models, and the pseudo second-order kinetic model could best describe the adsorption. The impacts of pH on RTB adsorption were also investigated. The experimental results indicated that the initial pH value was the important parameter affecting the adsorption of RTB, and the adsorption capacity of aerobic sludge decreased with the increase of pH value.
