Abstract:
The purpose of this study was to discuss the characteristics of sludge mixed liquor,as well as microbial structure of aerobic granular sludge in MBR.It found that the total sludge concentration of aerobic granular sludge increased,but the concentration of aerobic granular sludge declined gradually in aerobic granular sludge MBR.However the floc sludge concentration showed increasing steadily gradually in aerobic granular sludge MBR.The mean diameter of aerobic granular sludge decreased from 3mm to 2mm,and its settlement performance deteriorated with time in aerobic granular sludge MBR.The large number of EPS and soluble products produced and their concentrations increased gradually in MBR.The soluble products concentration and ESP had the same trend.By the mean of electric microscope,The microstructure of aerobic granular sludge was divided into two areas,external aerobic zone and internal an aerobic zone,filamentous bacteria inhabited mainly on the surface of the aerobic granular sludge,and bacillus mainly existed inside of it.
