用味精生产废水培养好氧颗粒污泥
Cultivation of Aerobic Granular Sludge Using Monosodium Glutamate Production Wastewater
摘要
Abstract
Using anaerobic granular sludge as seeding sludge and monosodium glutamate production wastewater as medium,aerobic granular sludge was cultivated in SBR with gradually shortening sludge sedimentation time.The experimental results show that:After 65 d of cultivation,the aerobic granular sludge with small size and tawny color are observed; After 95 d,the aerobic granular sludge tends to be mature with 0.6 mm of the size and surrounded with a mass of protozoa; At this time,MLSS is increased to 8.00 g/L and SVI is decreased to about 30.00 mL/g; The mature aerobic granular sludge has good effects on removal of COD and NH3-N fron monosodium glutamate production wastewater with about 80 mg/L of effluent COD and 2 mg/L ofp(NH3-N).关键词
