Embodiment 1
[0031] The endophytic bacteria were treated by three methods: injection, dipping and winding. pseudomonas reactans Colonize into the body of Hego taro (weighing about 25g) to establish Hego taro- pseudomonas reactans For the symbiotic purification system, 1 L of uranium wastewater with a uranium concentration of 1.0 mg / L was used to hydroponic the above-mentioned system (three parallel samples were set up), and a control group (three parallel samples were set up) was set up for the restoration of the fruit. The concentration of uranium in the wastewater See attached for changes over time figure 2. On the 10th day, the concentration of uranium in the injection, dipping and winding test groups all decreased to 0.375 mg / L, 0.629 mg / L and 0.497 mg / L, while that in the control group decreased to 0.501 mg / L. On the 21st day, the uranium content of the dipping and winding test groups dropped to 0.043 mg / L and 0.040 mg / L respectively, meeting the national emission standards. On ...

[0033] The endophytic bacteria were treated by three methods: injection, dipping and winding. pseudomonas reactans Colonize into the body of Hego taro (weighing about 25g) to establish Hego taro- pseudomonas reactans For the symbiotic purification system, 1 L of uranium wastewater with a uranium concentration of 5.0 mg / L was used to hydroponic the above-mentioned system (three parallel samples were set up), and a control group (three parallel samples were set up) was set up for the repairing of yam. The concentration of uranium in the wastewater See attached for changes over time image 3 ; On the 10th day, the uranium concentrations in the injection, dipping and winding test groups all decreased to 2.007 mg / L, 0.594 mg / L, 0.581 mg / L, and in the control group to 1.075 mg / L. On the 24th day, the uranium content of the dipping and winding test groups dropped to 0.039 mg / L and 0.035 mg / L respectively, meeting the national emission standards, while the rest of the groups did no...
