摘要
通过实验比较了不同粒径Anammox颗粒污泥的物理性质和处理效果的差异。实验结果表明,Anammox颗粒污泥粒径的增大有助于减小颗粒污泥受到的不利条件的影响;粒径为0.5~1.0、1.0~1.5 mm及1.5 mm以上3组Anammox颗粒污泥的比反应速率(以N计)分别为0.52、0.62、0.55 g/(g·d)。综合考虑去除效果及稳定性,在本实验系统中,粒径在1.0~1.5 mm的Anammox颗粒污泥的综合性能最佳。
Through experiments,the difference of physical property and treatment results of Anammox granule sludge with different grain sizes have been compared. The results show that the enlargement of Anammox granule sludge sizes is good for reducing the disadvantageous influence on granule sludge. The specific rates of reaction (by N) of the three groups of Anammox granule sludge(0.5-1.0 mm, 1.0-1.5 mm and above 1.5 mm) are 0.55,0.62 and 0.52 g/(g·d),respectively. The removing results and stability should be considered comprehensively,it is found that in this experimental system,the comprehensive property of Anammox granule sludge whose grain size is within the scope of 1.0-1.5 mm is the best.
