Cultivation of aerobic granule sludge and its application in treatment of monosodium glutamate wastewater
好氧颗粒污泥的培养及处理味精废水

Using anaerobic granular sludge as the vicinal sludge,after 35 days operation,aerobic granular sludge was formed in sequencing batch reactor.This SBR system showed a very stable organic carbon and ammonium removal performance.The removal rate for organic carbon and ammonium could reach more than 95% and 99%,respectively.This systerm was applied to monosodium glutamate wastewater treatment.Under the conditions of organic volume rate of 2.4 kg/(m3·d) and ammonia volume rate of 0.24 kg/(m3·d),the COD,NH+4-N and TN removal efficiencies could reach more than 90%,99% and 85%,respectively.After treat monosodium glutamate wastewater,the sludge particle size reduced from 0.8~2.5 mm to 0.6~1.8 mm,the granule structure was more strength.
