Abstract

Abstract

The successful cultivation of aerobic granular sludge with outstanding performance in airlift aerobic granular sludge bed reactor (AGSB) which was inoculated anaerobic granular sludge and aerobic flocculent sludge was performed using a synthetic wastewater mainly consisted of glucose as carbon source. The diameters of the granules ware 0.5-2.0mm and the sludge concentration in the reactor was in 5g/L or so. As the influent COD of 2000mg/L and the COD loading of 4.8kg/(m³·d) were employed, COD removal synthetic maintained more than 96%. Through the scanning electron microscopy observation, aerobic granular sludge was layered structure with a large number of filamentous bacteria winding on the surface, and some short bacillus and holes existing inside. After 47 days of cultivation, when the pharmaceutical wastewater completely replaced the synthetic water with gradually the increased pharmaceutical wastewater in the ratio of water, the COD, NH₃-N, TP removal synthetic were more than 90%, 90%, and 70% respectively.
