High flocculating activity strains were screened and cultivated from activated sludge，water sediment，plant roots
soil and strawberry planting soil． The flocculating activity of the strains was investigated by changing fermentation liquid
dosage，coagulant dosage，carbon and nitrogen sources，and applied in the heavy metal wastewater treatment． The results
showed that the strain QB1 can reach the highest flocculation rate of 93%，when using glucose as carbon source and yeast
extract as nitrogen source，with the bacteria liquid dosage of 0. 2 mL，and coagulant dosage of 0. 8 mL． The removal rate of
lead ion from the wastewater can be as high as 99% above．
