| 中文摘要: |
| 试验探讨了腐殖质还原菌去除U(Ⅵ)的特性与效果，重点考察了温度、pH、AQS、U(Ⅵ)浓度等因素对腐殖质还原菌去除U(Ⅵ)的影响.试验结果表明，腐殖质还原菌对低浓度U(Ⅵ)有很好的去除效果，其去除U(Ⅵ)的最适温度为30 ℃左右，最佳pH在 60左右，AQS的最佳用量约为10 mmol/L.红外光谱分析表明，羧基、酰胺基和磷酸基团是腐殖质还原菌除铀过程中占主导地位的官能团. |

| The characteristics and performance of the humic reducing bacteria(HRB) to remove U(Ⅵ) in wastewater were examined.The impact of temperature，pH values，AQS，electron donor sodium lactate and U(Ⅵ) concentrations was studied.Experimental results showed that HRB was efficent to remove low concentration U (Ⅵ).The optimum reduction U (Ⅵ) condition was that temperature was about 30 ℃，pH was about 60，AQS was about 10 mmol/L.The IR spectroscopic analysis suggested that carboxyl，amide and phosphate groups of humic reducing cell were the dominant functional groups involved in bacteria uranium interaction. |
