Study on Anaerobic Granular Sludge in Beer Waste Water Treatment
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.
