Abstract

In this study, granule activated carbon was adopted as carrier to speed up the cultivation of granular sludge in a UASB reactor treating beer waste water. The results showed the granulation process of UASB was finished just on day 63rd and the COD removal efficiency reached as high as 92% at volumetric loading rate of 15.0 kgCOD/(m³-d) after the addition of granule activated carbon. Mature granular sludge had perfect settling property and methanogenic activity with diameters of 0.83-2 mm. Bacterium community was abundant and distributed regionally inside the granular sludge. Furthermore, no in-core was discovered which indicated that the formation granular sludge was due to the second nuclear theory.
