【摘要】 从活性污泥中筛选出一株高效的微生物絮凝剂产生菌,初步鉴定为霉菌。该菌产絮凝剂与菌体生长相关,在菌生长的稳定期后,达到最佳的絮凝效果。该絮凝剂主要为胞外产物,只有很少部分存在于菌体中。高岭土絮凝实验结果表明,该菌产絮凝剂在不添加任何助凝剂的情况下,絮凝率达到95.08%。该絮凝剂对城市污水的浊度去除率为88%。更多还原

【Abstract】 A strain which was preliminarily identified as mould screened from the activated sludge can produce a high efficient bio flocculant.The production of the flocculant correlates with the growth curve of the bacterium.The flocculation reaches its highest after the stationary stage.The main flocculant exists in the extracellular fluid.Experiments on kaolin suspension with produced bio flocculant show that the flocculation efficiency achieves 95.08%without any aids and those on sewage show 88%of turbidity removal.更多还原
