Abstract: With the rapid development of nuclear power, the prevention and remediation of radioactive uranium contaminated soil has become an urgent problem to be solved. The current bio-remediation technologies for uranium contaminated soil were summarized in this paper through literature reiew, including phyto-remediation, microbial remediation, phyto-microbial combined remediation, as well as phyto-microbial-chelating agent combined remediation technology. Finally, according to the research results and current work, it is proposed that the future research direction should focus on the following aspects: (i)Improvement of chelating agent; (ii)Cultivate hyperaccumulation plants with engineering application value and shorten the plant growth cycle; (iii)use the existing laboratory research results to the field remediation of large-area uranium contaminated soil to achieve the purpose of engineering application; (iv)Reasonable volume reduction, harmless treatment and reuse of the remediation plants are carried out to find new technologies for the treatment of the remediation plants.

Key words: Uranium contaminated soil, Bio-remediation technologies, Combined remediation, Influence factor
