The Research of Cultivated Sludge rapidly of UASB and Methanogenic
Abstract：
Based on the two-phase anaerobic reactor, the quick cultivation of granular sludge and its characteristics in methanogenic UASB were studied. Start-up at low loading rate, quick increasing of the influnt COD and shortening of HRT cause methanogenic UASB to be operated under optimal condition. After 36 days of operation, 64% of total granular sludge is more than 1.0 mm, the effluent COD is less than 300 mg/L. It is believed that the cultivation of granular sludge is successfully achieved. The maturation of granular sludge experiences four stages including formation of irregular core, extrusion and bridging,division and growth, shear and accretion. Besides, the factors accelerating the sludge granulation include the appropriate growing environment, god hydraulic characteristics and so on.
