| 摘 要： | 目前,广泛应用于水处理的无机絮凝剂存在用量大、絮凝效果欠佳、易(如铝盐絮凝剂)造成二次污染的缺陷,而大多数人工合成有机高分子絮凝剂的残留单体又会对人体造成毒害(如聚丙烯酰胺).因此,探索和开发新一代具有无毒、无害、无二次污染絮凝剂已经成为水处理研究领域的热点.微生

| Abstract: | 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. |
