低水力负荷下好氧颗粒污泥的特性及胞外聚合物关键组分对该污泥稳定性的影响OACSTPCD
Characteristics of Aerobic Granular Sludge under Low Hydraulic Loading and Effect of Key Component of Extracellular Polymeric Substance (EPS) on Stability of the Sludge
使用一种快速启动SBAR反应器培养好氧颗粒污泥,在此基础上研究污泥颗粒化过程与解体过程中好氧颗粒污泥的特性、反应器对污染物的去除效果以及三种胞外聚合物(EPS)关键组分含量的变化对颗粒污泥稳定性的影响.结果表明:(1)在低水力负荷条件下,通过缩短沉淀时间、改变进水基质浓度等措施,反应器在92 d时完全形成淡黄色、小粒径、不规则形状的颗粒污泥;同时完全颗粒化后,SVI保持在50 mL/g以下,MLSS保持在4.0 g/L以上.(2)在144 d的运…查看全部>>
By cultivating aerobic granular sludge in a quick start-up SBAR reactor,research on the characteristics of aerobic granular sludge in the process of sludge granulation and disintegration,removal efficiencies of the pollutant by the reactor,as well as influence of the key component changes of three EPS on the stability of the sludge,was introduced.The results showed that:(1) Under low hydraulic condition,particles of light yellow,small size and irregular shap…查看全部>>
