Abstract:
The process of anaerobic sludge granulation in UASB reactor for treating corn starch wastewater has been investigated. The study is unique in that the tiny bacterial flocculating units are observed and the model of sludge granulation is established. The results indicates that under the condition of ensuring the biological activity， providing enough sludge load and controlling the hydraulic condition of the system have the most important effect on the rapid formation and development of the initial granules.
