复合微生物产絮凝剂的絮凝性能研究

Study of flocculating capability on flocculation producing by effective microorganisms

研究表明，复合微生物产絮凝剂对高岭土悬浮液絮凝率可达90％．添加适当助剂絮凝率可提高至96％，pH值为2-12，絮凝率均可达到92％。且热稳定性良好．对实际废污水絮凝率迭85％-96％．该絮凝剂初步分析为酸性多糖物质．

The result of the study on the flocculation property of microbial flocculant which was produced by effective microorganisms shows that the flocculating efficiency of flocculating kaolin soliquoid is 90%, the efflciencies will be increased to more than 96% by adding some assistant reagent, and the efficiency is over 92% with the pH value at the range of 2 - 12. The microbial flocculant has a good stability of heat. The flocculating efficiency on several kinds of waste water is from 85% - 96%. The result shows that this microbial flocculant is a sort of polysaccharide by biochemical reaction and infrared spectrum.
