摘　　要：Bioflocculants have received increasing attention in research because they are low cost,non-toxic,biodegradable,operationally simple and useful in many water and wastewater treatment applications.In this study,we focused mainly on the screening of the flocculant-producing strain and its application in oily wastewater treatment.Bacteria strain B-6-1 was isolated by the pyridine screening method.UPC-1 reagent produced by B-6-1 had efficient flocculating activity.It was deduced that the main component of UPC-1 reagent was polysaccharide through purification and analysis.The influence of dosage of reagent,pH value,temperature and oil concentration on the flocculation effect of UPC-1 reagent was investigated.Bioflocculants have received increasing attention in research because they are low cost, non-toxic, biodegradable, operationally simple and useful in many water and wastewater treatment applications.
