| Abstract: | In order to study the characteristics of aerobic granular sludge in WSBR, the granulation effects of aerobic active sludge in WSBR were compared with that in traditional SBR. The results indicated that with the same amount of PAM, aerobic active sludge was found on 4th day in WSBR with reasonable secondary flow field, while it was not found in SBR until on 10th day. Moreover, the diameters of most aerobic active sludge found in WSBR were within the range of 0.9~1.5mm, SVI was around a stable value of 50mg •L-1, the specific gravity of granular sludge was increased by 0.0509, VSS was increased to 81.32%, SOUR reached to 1.387mg•(min•g)-1 and the percentage of contained water of sludge reached to 93.23%. Considering the structure of microorganism, the compact bacteria structure of aerobic granular sludge found in WSBR was much better than that formed inSBR,which indicated that with reasonable secondary flow field, good aerobic granular sludge could be rapidly formed by applying PAM coagulation sedimentation theory. |
