| Abstract: | 12 strains, which can produce microbial flocculant, were isolated from activated sludge and soil by means of the regular bacteria isolation and purification method. And a strain named MBFP-7, which can produce bioflocculant with high flocculating activity, was found out from the 12 strains. Kaolin suspension was treated with MBF and show that the temperature, pH, the amount of MBF and Ca2 + influence the flocculating activity. And then this paper studied the flocculating mechanism of MBF. |
