Abstract:
The aerobic granular sludge membrane bioreactor worked for 75 days. In this operation, the removal efficiencies for COD, NH4+ -N and TN were 91%-95%, 89.57%-100% and 48.25%-90.84%, respectively. The granular sludge appeared disintegration to some extent and the sludge settlement performances deteriorated. Sludge specific resistance from initial resistance of 1.085 x 10(13) m/kg rose to 2.712 x 10(13) m/kg at the end; extracellular polymeric substances maintained between 44.71 and 72.23 mg/g. Then, pollution characteristics of the membrane module were studied. It was found that membrane surface cake layer resistance and membrane pore plugging resistance were 5.32 x 10(11) m(-1) and 2.34 x 10(11) m(-1), accounted for the total resistance of 67.42% and 29.66%, respectively. Through the analysis of infrared spectrum for membrane fouling matters found that the main fouling matters were proteins and carbohydrate materials for membrane.
