摘要
采用钌红吸附法测定胞外多聚物的研究结果表明,厌氧颗粒污泥形成后污泥中胞外多聚物含量有所增加;钌红定位染色表明,颗粒污泥中胞外多聚物主要分布在球菌细胞间,而在丝菌等细胞间胞外多聚物分布较少。这些结果说明胞外多聚物在颗粒污泥形成过程中具有一定的作用,但并不是颗粒污泥形成与否的决定因素.
Experiments were conducted to eluciate the role of extracelluar polymers in anaerobic sludge gra- nnlation in UASB reactor.The results showed that the amount of extracellular polymers increased in the granular sludge compared with the amount of seeding sludge.By ruthenium red staining and electron microscopic observation,it was found that the extracellular polymers distributed between cells of cocci with less amount between filamentous or rod cells.These results revealed that extra- cellular polymers played a cohensive role in anaerobic sludge granulation but it was not the decisive factor controlling anaerobic sludge granulation,
