| Abstract: | Flocculant-producing bacterium named as C4-3 which had higher and stable flocculation activity was isolated from the activated sludge,and its flocculation activity and flocculation conditions were investigated.The result showed that,the flocculation active substances produced by C4-3 were mainly its extracellular metabolites.For 1~7 g·L-1 Kaolin clay suspension,the bioflocculant exhibited effective flocculation performance under the conditions as follows: bioflocculant amount of 1 mL·(100 mL)-1,coagulant aid 1% CaCl2 amount of 1~6 mL,pH value of 8.0~11.0.In addition,the bioflocculant could be applied in a wide pH value range with good thermostability,so it was suitable for industrial production. |
