摘要/Abstract

摘要： 为探讨好氧颗粒污泥对有机污染物的吸附机制，采用动态吸附方式研究好氧颗粒污泥对有机污染物的初期吸附作用，采用静态吸附方式考察好氧颗粒污泥失活前后对有机污染物吸附效率的差异，分析了好氧颗粒污泥吸附有机污染物前后的热力学参数及红外光谱变化。结果表明，好氧颗粒污泥对有机污染物的吸附过程表现出了明显的初期吸附去除现象，30 min内对有机污染物吸附去除率达60.19%。好氧颗粒污泥吸附有机污染物是一个自发、吸热、熵增的过程，且吸附过程是一个以物理吸附为主、生物吸附和化学吸附为辅的复杂过程。

Abstract: In order to explore the adsorption mechanisms of aerobic granular sludge to organic pollutants, the initial adsorption of aerobic granular sludge to organic pollutants was studied using the model of dynamic adsorption. The differences of adsorption efficiency between living and non-living aerobic granular sludge were also studied using the model of static adsorption. The adsorption the rmodynamic parameters and the infrared spectrums of the aerobic granular sludge before and after adsorption were analyzed. The results indicate that the removal efficiency during the initial adsorption is obvious, and which can reach 60.19% in 30 minutes adsorbing. The adsorption of aerobic granular sludge to organic pollutants is a process of spontaneous with endothermic and entropy increasing, in which the physical adsorption plays a primary role with a supplement of biological and chemical adsorption.

Key words: aerobic granular sludge, initial adsorption, organic pollutant, adsorption mechanism
