| 摘 要： | 在SBR反应器中对活性污泥进行颗粒化培养,研究了活性污泥在颗粒化过程中的理化性状及脱氮性能.结果表明,活性污泥颗粒化过程可以分为颗粒形成、颗粒生长和颗粒成熟3个阶段.第1阶段SVI值迅速降低,在30 d内由接种时的110mL/g降低到23 mL/g;第2阶段颗粒粒径迅速增加,在15 d内由0.25 mm增加到0.82 ...

| Abstract: | The physicochemical characteristics and denitrogenation of sludge during granulation were investigated in SBR.It was revealed that the process of granulation can be divided into three stages,including formation,growth and mature stage.In the first stage,the settling ability of sludge was improved obviously,SVI decreased from 110 mL /g to 23 mL /g during the first 30 days;In the second phase,aerobic granule grew rapidly,the mean diameter increased to 0.82 mm from 0.25 mm in the following 15 days,the value of... |
