Abstract
Orthogonal test was employed to inspect the flocculation of Rhodopseudomonas spheroides in this text. The result showed that Rhodopseudomonas spheroides has good performance in flocculation effect of coal slurry. The hightest flocculation ratio is 93.4%. The optimum technological combination of flocculation test has been obtained:incubation time:12h,Coagulation aid dosage:2mL,Bacterium fluid amount:2mL,The categories of flocculants: the cell homogenates,pH:7.The FTIR analysis showed that the extractive of Rhodopseudomonas spheroides contain a large number of acidic Polysaccharides which has flocculent effect component.The main flocculation is “adsorption-bridge” between Molecular bioflocculant and coal slurry.
