Background: with the increasingly serious global water pollution, industrial and agricultural wastewater treatment is becoming more and more important. Flocculant precipitation is the first process in wastewater treatment. One of the keys to achieve efficient water purification is to add microbial flocculant with excellent performance. Objective: the research of high-efficiency and non-toxic microbial flocculant for wastewater treatment has increasingly become important in environmental protection. Method: CMC-Na medium and dilute iodine staining was used to separate and screen flocculant producing bacteria. The distribution of flocculant activity and the effect of different types of wastewater treatment were studied. Results: the flocculant producing strain 71-1 separate from ruminant feces was identified as Cellulosimicrobiums sp. The flocculating rate of MBF-P71 was 97.83%, which had obvious degradation effect on COD value of pig farm manure water and ship port sewage. The removal rates of cod were 66.95% and 46.68% respectively. Conclusion: MBF-P71 has the advantages of good flocculation effect, low production cost, high efficiency and low dosage. It has a good development and application prospect for wastewater treatment.
