| 摘 要： | 从吉林污水处理厂活性污泥中筛选出一株高效絮凝铜离子的菌株，通过16S rDNA扩增和菌株鉴定。鉴定其为植生乌拉尔菌(Raoultella planticola)，研究了生物絮凝剂对铜离子(0.2ppm)的絮凝条件。结果表明，絮凝效率达到80%以上。影响絮凝效率的主要因素和变量为pH、絮凝时间。在pH=5、1.62h 、氧化石墨烯Graphene Oxide（GO）助凝诱导剂13.11mg/L时，絮凝效率达到86.01%，达到最高的絮凝效率。

| Abstract: | A strain of high efficiency flocculating to improve the removal of copper ions was selected from activated sludge of Jilin sewage treatment plant, and was amplified and identified by 16 S rDNA. The flocculating conditions of copper ion (0.2 ppm) by bioflocculant were studied. The results show that the flocculation efficiency is over 80%. Significant influencing factors and variables were pH, flocculation time and Graphene Oxide (GO) inducer which had major impact effects on flocculation efficiency. The highest flocculation efficiency which 86.01% achieved at pH=5, at 1.62h and 13.11mg/L GO as inducer. |
