摘要
以厌氧颗粒污泥为接种污泥,分别采用人工配水、味精废水培养出好氧颗粒污泥。结果表明:人工配水培养的颗粒污泥55 d可培养成功,为黄色,平均粒径为2 mm,SVI约为20 m L/g,ρ(MLSS)为10 g/L,该系统对人工配水COD、NH+4-N平均去除率分别为94%、97.5%;味精废水培养的好氧颗粒污泥95 d可培养成功,为黄褐色,平均粒径为0.6 mm,SVI约为30 m L/g,ρ(MLSS)可达到8 g/L,该系统对味精废水COD、NH+4-N平均去除率分别为90%、95%。
The anaerobic granular sludge was inoculated in SBR reactor with artificial water and monosodium glutamate wastewater to cultivate aerobic granular sludge. The research showed that： the granular sludge cultured with artificial water could be achieved after 55 d, with its average particle size of 2 mm in mature stage, SVI of 20 mL/g, MLSS of 10 g/L, average removal rates of COD, NH4＋ -N were 94% , 97.5% in the system of artificial water; aerobic granular sludge cultured with monosodium glutamate wastewater could be achieved after 95 d, average particle size of aerobic granular mature tawny was O. 6 mm, SVI of 30 mL/g, MLSS of 8 g/L, the average removal rates of COD, NH4＋ -N were 90% , 95% , respectively in the system of monosodium glutamate wastewater.
