摘　　要：以厌氧颗粒污泥为接种污泥,在模拟废水条件下利用SBR 35 d成功培养出了具有同步硝化反硝化作用的好氧颗粒污泥,反应器对COD和NH4+-N去除率分别高于95%和99%。将该反应器用于处理味精废水,当COD、NH4+-N的容积负荷分别为2.4 kg/(m3.d)、0.24 kg/(m3.d)时,COD、NH4+-N和TN去除率分别高于90%、99%和85%。处理味精废水后的颗粒污泥粒径由之前的0.8～2.5 mm减小至0.6～1.8 mm,颗粒结构较之前更加密实。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.
