Application Progress of in Biological Treatment of Radioactive Uranium-Containing Wastewater.

Radioactive uranium wastewater contains a large amount of radionuclide uranium and other heavy metal ions. The radioactive uranium wastewater discharged into the environment will not only pollute the natural environment, but also threat human health. Therefore, the treatment of radioactive uranium wastewater is a current research focus for many researchers. The treatment in radioactive uranium wastewater mainly includes physical, chemical and biological methods. At present, the using of biological treatment to treat uranium in radioactive uranium wastewater has been gradually shown its superiority and advantages. is a famous microorganism with the most radiation resistant to ionizing radiation in the world, and can also resist various other extreme pressures. can be directly used for the adsorption of uranium in radioactive waste water, and it can also transform other functional genes into to construct genetically engineered bacteria, and then applied to the treatment of radioactive uranium containing wastewater. Radionuclides uranium in radioactive uranium-containing wastewater treated by involves a lot of mechanisms. This article reviews currently the application of that directly or construct genetically engineered bacteria in the treatment of radioactive uranium wastewater and discusses the mechanism of in bioremediation of uranium. The application of constructing an engineered bacteria of with powerful functions in uranium-containing wastewater is prospected.
