摘要
在IC反应器上进行了蚯蚓粪作为添加剂对厌氧污泥颗粒化影响的试验。观察分析了污泥外观、微生物相,测试分析了污泥VSS/TSS与SVI变化、污泥粒径分布、污泥沉降速度。结果表明,蚯蚓粪为形成污泥颗粒提供附着体,促进具有良好沉降性能的厌氧颗粒污泥的形成。
Effects of vermicompost on granulation of anaerobic sludge in IC reactor was studied.The appearance and microbiofacies of anaerobic granular sludge were observed and analyzed.The VSS/TSS and SVI change,size distribution,Sedimentation velocity of anaerobic granular sludge were tested and analyzed.The results showed that vermicompost granule provided the attachment and promoted the formation of anaerobic granular sludge with good settling performance.
