  • 摘要: 实验研究了中试规模下,以城市剩余污泥接种IC反应器处理大豆蛋白废水时,厌氧颗粒污泥的驯化和反应器的启动过程。控制反应器内废水的温度在30~38℃、pH在6.8~7.5和挥发性脂肪酸(VFA)不高于600~800 mg/L的条件下,经过98 d运行,IC反应器对COD去除率达到80%~90%,容积负荷达到9.5 kg COD/(m3·d)。成熟厌氧颗粒污泥为黑色,边界清晰,呈椭球形,平均粒径d50为1.5 mm,粒径>1 mm的颗粒占92.3%。扫描电镜观察发现,颗粒污泥中产甲烷鬓毛菌(Methanosaetaceae)占优势。
    Abstract: Granular sludge acclimation and start-up of a pilot-scale internal circulation (IC) anaerobic reactor and its application for the treatment of soybean wastewater were evaluated during this research. Reaction temperature was kept between 30℃ and 38℃, pH was in the range from 6.8 to 7.5, and volatile fatty acids (VFA) were less than 600 to 800 mg/L. After 98 days of incubation, granular sludge acclimation was achieved, with a COD removal efficiency of 80% to 90% and an organic loading rate of 9.5 kg COD/(m3·d). Mature granular sludge was black and ellipsoid with clear boundaries. The average particle size (d50) was 1.5 mm, and 92.3% of the particles were larger than 1 mm. The dominant archaea in the mature granular samples was Methanosaetaceae, which was determined using scanning electron microscopy.
