  • 摘要: 采用西安市第四污水处理厂A2/O系统中的絮体污泥为接种污泥,在连续流传统活性污泥系统中进行了好氧颗粒污泥的培养研究。当系统温度为25~27℃、沉淀时间为2 h、溶解氧为4.2 mg/L、搅拌速度为240 r/min时,系统可培养出粒径为0.5~1.5 mm的颗粒污泥,扫描电镜结果显示,颗粒污泥主要由球状菌和杆状菌组成,此外还存在少量的丝状菌。实验结果表明,相对于反应器的形式和沉淀时间,水力剪切力和接种污泥中的丝状菌对好氧颗粒污泥形成的影响更大,胞外多糖的产生对好氧颗粒污泥的形成也起着至关重要的作用。
    Abstract: Aerobic granules cultivated was carried out in a conventional continuous flow activated sludge system(CAS)inoculated with flocculated sludge from the 4th MWWTP of Xi'an. Aerobic granules of 0.5~1.5 mm in diameter could be successfully cultured at 25~27℃, settling time of 2 hours, DO of 4.2 mg/L and stirring rate of 240 r/min, Scanning electron microscopy (SEM) investigation showed that sphere-like and rod-like bacteria were predominant in the aerobic granules, and only few filaments in the granules. The results showed that, by comparison with reactor pattern and settling time, shear force and filaments in the seeding sludge might have stronger influence on aggregation of floc sludge to form granules. In addition, extracellular polysaccharides were also important for the formation of aerobic granules.

摘要: 采用西安市第四污水处理厂A2/O系统中的絮体污泥为接种污泥,在连续流传统活性污泥系统中进行了好氧颗粒污泥的培养研究。当系统温度为25~27℃、沉淀时间为2 h、溶解氧为4.2 mg/L、搅拌速度为240 r/min时,系统可培养出粒径为0.5~1.5 mm的颗粒污泥,扫描电镜结果显示,颗粒污泥主要由球状菌和杆状菌组成,此外还存在少量的丝状菌。实验结果表明,相对于反应器的形式和沉淀时间,水力剪切力和接种污泥中的丝状菌对好氧颗粒污泥形成的影响更大,胞外多糖的产生对好氧颗粒污泥的形成也起着至关重要的作用。
