| Abstract: | Bacterium were isolated and purified by 5 kinds of different culture mediums from microorganism in soil irrigated with wastewater in Tongliao,and nine bioflocculant producing bacterium were screened out.Nine kinds of high-efficient complex bioflocculant producing bacterium were screened with the compound methods of C92 and C93.The rate of flocculation reached 100% to Kaolin clay suspension.The largest output was 3.5 g/L when distilled by ethanol and the rate of the transform reached 18.9%.The result was satisfying when they were applied to dyestuff water and common wastewater.It provids high-efficient bacterium for further research on the complex microbial flocculant. |
