摘要

以厌氧颗粒污泥为生物吸附剂，对含铜废水的生物吸附与解吸进行了研究。结果表明，颗粒污泥的吸附率可达97.67%，柠檬酸的解吸效果最好。动力学模型和热力学等温吸附模型的研究表明，拟二级动力学模型和Langmuir等温吸附模型均能拟合Cu2+的吸附，且具有较高的相关系数，R2=0.9999, R2=0.9934。

Study on Biosorption and Desorption of Copper-Containing Wastewater by Anaerobic Granular Sludge

Using the anaerobic granular sludge acted asbiosorbent, this paper studied the biosorption and desorption of copper-containing wastewater. The results showed that, granular sludge adsorption rate up to 97.67% and citric acid got best desorption efficiency. The study of kinetics model and thermodynamics isotherm adsorption model showed that Pseudo-second Order kinetic model and Langmuir isothermal adsorption model could fitting the adsorption of Cu2+, which obtained high correlation coefficient, R2=0.9999 andR2=0.9934, respectively.
