Research progress of uranium contaminated soil remediation technology

Environmental pollution caused by uranium and its decay products is a serious problem on the global scale, which not only leads to ecological risks, but also poses a threat to human health. Therefore, how to effectively solve uranium-contaminated soil and improve the uranium-contained soil remediation technology system is the key to achieve sustainable development of uranium mining and metallurgy. At present, there are mainly three types of remediation technologies for uranium-contaminated soil: physical-chemical remediation, biological remediation and combined remediation. Firstly, this review summarizes the morphology and hazards of uranium in soil, as well as the research status, advantages and disadvantages of various remediation technologies. Then the influencing of uranium contamination remediation are also described. Finally, the existing challenges of uranium contaminated soil remediation are summarized, and the future development of remediation technology in this field is prospected. The purpose of this study is to fully combine environmental factors and the applicability of various remediation methods in practical application, the appropriate remediation technology is selected to achieve the efficient removal of uranium from contaminated soil.
