| 摘 要： | 采用静态生物淋洗法处理含2,4-二硝基甲苯-3-磺酸钠(2,4-DNT-3-SA)的土壤。考察供氧条件、土水比及温度对2,4-DNT-3-SA去除效果的影响,结果表明,在好氧、37oC、土水比为10:5的条件下,2,4-DNT-3-SA去除率最高,达到98.75%。采用高通量测序法分析土壤中微生物菌落结构及多样性,结果表明,土壤中的优势菌属主要为假单胞菌属、鞘脂菌属和芽孢乳杆菌属。

| Abstract: | A static biological leaching method was used to treat the 2,4-DNT-3-SA contaminated soil. The effects of oxygen conditions, soil to water ratio and temperature on the removal efficiency of 2,4-DNT-3-SA were evaluated. The result suggested that under the aerobic and 37oC conditions, the removal efficiency of 2,4-DNT-3-SA reached more than 98% when the ratio of soil to water was 10:5. High-throughput sequencing results indicated that the dominant bacteria in the soil were Genus Pseudomonas, Sphingobium and Sporolactobacillus. |
