摘要
以味精厂废水厌氧污泥混合普通活性污泥作为接种污泥,采用味精废水在SBR反应器内培养好氧颗粒污泥,通过预曝气调整进水负荷,经95 d成功培养出好氧颗粒污泥。培养出的颗粒污泥呈黄色,轮廓整齐,平均粒径为0.5 mm,对COD和氨氮的平均去除率高达91.8%和96.6%,反应器内SVI值保持在20mL/g左右,污泥质量浓度达8 000 mg/L左右。
The anaerobic granular sludge is combined with aerobic activated sludge as seeding sludge and after 95 days arobic 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.
