不同污泥对印染废水中残余染料的吸附特性OACSTPCD
Adsorption Characteristics of Different Kinds of Sludge for Residual Dyes in Printing and Dying Wastewater
研究了四种不同污泥(活性污泥、厌氧污泥、干活性污泥、干厌氧污泥)对染料阳离子嫩黄X-4GL的吸附,并考察了胞外聚合物(EPS)在此过程中所起的作用.结果表明四种污泥对阳离子嫩黄的吸附在90min内基本达到平衡,干活性污泥的吸附性能最好,干厌氧污泥的吸附性能最差,污泥浓度为250 mg/L时,其吸附量分别为133和50 mg/g.吸附量与染料平衡浓度之间符合Freundlich模型(R2为0.828～0.947),又符合Langmuir模型(R2为…查看全部>>
The adsorption of a dye named Cationic Bright Yellow, by four kinds of sludge including activated sludge, anaerobic sludge, dried activated sludge, and dried anaerobic sludge was investigated in this paper. The roles of extracellular polymeric substances (EPS) for the biosorption of activated sludge and anaerobic sludge were further studied. The results show that the equilibrium between dye and different kinds of sludge is achieved within 90 min. The adsorpt…查看全部>>
