Research on Micro-Aerobic Granular Sludge in the Process of Cultivation

Abstract:

Taking granular sludge, the anaerobic granular sludge and the aerobic granular sludge were treated by IC reactor. According to the changes of COD, SS and so on removal rate of out-flow water, the granular sludge was judged to turn into particles degree. The result indicate that when the influent organic load upgrade 385.7g COD/d eventually after 8 times, the HRT reaches 5h, the reflux is 1.4L/h, removal rate of COD is 84.7%. The SS concentration of out-flow water fluctuated largely throughout the experiment. During the experimentation, it was found that if the water content was higher and the density was lower in the micro-aerobic, the anaerobic granular sludge disintegrated seriously, particle size showed a narrowing trend and a large number of fragments fell and suspended in reactor.
