The anaerobic granular sludge is combined with aerobic activated sludge as seeding sludge and after 95 days aro-bic granular sludge is successfully cultivated in SBR reactor by preaeration and adjusting influent loading with monosodium glutamate wastewater .The colour of particle presents yellow and the outline is neatly observed with its average particle size about 0 .5 mm .In mature cultivation period ,the average removal rate of COD and nirogen can reach 91 .8% and 96 .6%respectively ,parameter of SVI is maintained at about 20 mL/g and the concentration of sludge reaches about 8 000 mg/L .
