| 摘 要： | 从土壤中分离筛选出一株絮凝剂产生菌,命名为C-2,通过nPCR扩增试剂盒鉴定得出这株絮凝剂产生菌为荧光假单胞菌(Pseudomonas fluorescens);絮凝性能实验表明:生物絮凝剂(命名为PS-2)在碱性条件下,以CaCl2作为助凝剂处理高岭土悬浊液时,用量仅为20mL/L,搅拌强度要求不高,能够使高岭土的絮凝率达到98%以上,絮体形成快,矾花大,沉降速度快,且温度的影响不大;将PS-2应用于多种高浊度废水的处理中,结果表明其对多种废水均具有良好的絮凝效果;成分分析表明PS-2是一种多糖和核酸的混合物。 |

| Abstract: | A bioflocculant-producing bacterium named C-2 was isolated from soil.The strain was identified as Pseudomonas fluorescens by nPCR amplification kit,and flocculating experiment showed that in alkali condition and at the presence of CaCl2,the bioflocculant named PS-2 had high efficiency with small dosage for dealing with kaolin suspension with larger floc,rapid sedimentation rate over a wide range of temperature.The bioflocculant had good flocculation activity to many kinds of wastewater.Component analysis showed that PS-2 was composed of polysaccharide and nucleic acid. |
| Keywords: | bioflocculant bacteria identification flocculation property component analysis |
