| 摘 要： | 采用好氧和厌氧污泥进行污泥的生物吸附实验,研究好氧与厌氧污泥吸附动力学和吸附平衡模型。研究表明:好氧和厌氧污泥的吸附过程中,颗粒内扩散是污泥吸附的主要限速阶段,但它不是唯一的限速因素。好氧和厌氧污泥的假二级反应模型比一级、二级反应模型更能描述污泥的吸附过程。Langmuir和Freundlich的吸附平衡方程都适合描述厌氧和好氧污泥的吸附平衡过程。

| Abstract: | Adsorptive kinetics and equilibrium models were investigated by experiment of both aerobic and anaerobic sludge adsorption.The results showed that Although the adsorption of both aerobic and anaerobic sludge was governed by intraparticle diffusion process,it was not main rate determining step through the adsorption.Both anaerobic and aerobic sludge adsorption process followed the pseudo second order model rather than first order model or the second model.The equilibrium data fitted well to both the Freundli... |
