Progress of uranium-contaminated soil bioremediation technology

With the extensive exploitation of nuclear energy and uranium, the problem of uranium-contaminated soil is becoming increasingly prominent. In recent years, various technologies for remediation of uranium contaminated soil have emerged, such as bioremediation, physical remediation and chemical remediation. Bioremediation technology has the widespread attention because of its environmental friendliness, low cost and high economic benefits. This paper mainly reviews the evaluation index of uranium-contaminated soil, soil remediation technology and its advantages and disadvantages, introduces especially the research status of soil bioremediation technology in detail, and puts forward some suggestions and prospects for bioremediation of uranium-contaminated soil.
