Embodiment 1
[0026] The initial concentration in uranium-containing wastewater is C 0 =50mg / L, cell concentration C b Under the condition of =0.3g / L, put live bacteria into the uranium-containing wastewater with pH of 3, 4, 5, 6, 7 and 8 respectively. After 60 minutes of treatment, the content of uranium in the water was detected respectively. When the pH value was 6, the removal rate and removal amount of uranium both reached the maximum, which were 81.2% and 135.3mg / g respectively, which had a good removal effect.
Embodiment 2
[0028] When the initial concentration of uranium-containing wastewater is 50mg / L, the bacterial cell concentration C b = 0.3g / L, adjust its pH to 6.0, and detect the content of uranium in the water after the treatment time is 5, 15, 30, 60, 120 and 180min respectively. The maximum removal rate reached 81.5% when the treatment time was 60 minutes, and then it was in a dynamic equilibrium process.
Embodiment 3
[0030] In the case of pH=6, maintain the cell concentration C b = 0.3g / L, put live bacteria into water bodies with initial uranium concentrations of 5, 10, 20, 50, 80 and 100 mg / L, respectively, and detect the uranium content in the water after 60 minutes of treatment. The bacterium has a high removal rate at low concentration, and the removal rate is still as high as 82.2% when the initial concentration is 50mg / L.
