摘要：

Upflow anaerobic sludge blanket reactors were started up, using a stepped loading regime, on a dairy waste prepared from raw ice-cream production waste from an ice-cream manufacturing plant. One UASB was supplemented with methanol. Granules were detected in the methanol-fed UASB at 3 weeks after start-up. The maximum load of 6·7 kgCOD m-3 day-1 with an HRT of 0·75 days could not be sustained during the 73 days of operation. Complete granulation had, however, occurred by the 4th week. Methanol addition at start-up aided rapid biomass granulation, and enhanced the settling velocity and specific activity of the sludge. However, wash-out was severe and residual biomass was sensitive to methanol withdrawal and produced no net growth. © 1990.
