| 摘 要： | 试验对比了苄基季铵盐(BAC)在好氧活性污泥和灭活好氧污泥的吸附平衡和吸附动力学。结果表明,2种污泥对BAC的吸附都在30 min达到平衡;随着BAC初始含量的增大,好氧污泥的吸附量增大,吸附率降低;伪2级较伪1级反应动力学模型更符合吸附试验。15～35℃下,BAC在好氧活性污泥的吸附行为可以很好地用Langmuir和Freundlich吸附等温方程描述,温度升高吸附能力降低,在15、25、35℃时,最大吸附量分别为315、307、277mg·g-1;25℃时灭活好氧污泥对BAC的吸附方程也同时符合Langmuir和Freundlich方程,最大吸附量为210.7 mg·g-1。好氧活性污泥的吸附性能强于灭活好氧污泥,2者都能有效地的吸附去除BAC。

| Abstract: | Adsorption kinetic and isotherm assays of Benzyl quaternary ammonium compounds(BAC) from aqueous solution on aerobic activated sludge and inactivated sludge was comparatively investigated through batch experiments.The equilibrium was achieved within 30 min of contact time.The adsorption of BAC on aerobic activated sludge and inactivated sludge was analyzed using pseudo first-order and pseudo second-order kinetic models,and the adsorption process followed pseudo second-order kinetic model.The adsorption isot... |
