摘要
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.
