In order to understand the effect of low temperature on the formation process of aerobic granules and contaminants removal characteristics,the aerobic granules-membrane bioreactor (AGS-MBR) has been started up and operated at low temperature using the carbon resource of sodium acetate.Aerobic granules cultivated in AGS-MBR possess smooth surface and compact structure in morphology as well as better settling property and higher biomass after 38 days.The average parameters of aerobic granules are:diameter 3.1 mm,wet density 1.041 g/mL,sludge volume index 42.35 mL/g and settling velocity 20.6 -45.2 cm/min.During the start-up of AGS-MBR,the respectively average contaminants removal efficiencies at low temperature are 91.9％ for chemical oxygen demand ( COD),89.2％ for NH4 + -N and 86.3％ for PO43- -P,and the overgrowth of filamentous bacteria has been well controlled.In addition,the hollow fiber microfiltration (MF) membrane fouling is light and the regime membrane layer is capable of enhancing membrane filtration as well as the average growth of trans-membrane pressure (TMP) is 1.07 kPa/d.Compared with the conventional cultivation of aerobic granules,the sludge granulation time significantly decreases from 73 days to 38 days by the application of microfiltration membrane at low temperature.
