Abstract

The invention relates to a biological surfactant functional modification method for deinococcus radiodurans (DR). The biological surfactant functional modification method comprises the following steps: firstly embedding rice straws and rice husks in farmland soil for composting, carrying out enrichment cultivation, ferment cultivation and flat chemical cultivation primary screening to obtain a biological surfactant bacterial strain liquid, carrying out functional modification on the deinococcus radiodurans (DR) to obtain a biological surfactant functional modification deinococcus radiodurans (DR) adsorbent, and applying the adsorbent to uranium-polluted water body repair. The method disclosed by the invention uses natural resource biomasses as raw materials, and is free of toxicity or pollution to the environment, so that recycling and resource recovery of natural resources are realized. Meanwhile, the method is simple and mild in reaction conditions, the obtained adsorbent can enable the content of uranium in a uranium-polluted water body with the concentration of 0.45-0.50 mg / L to be decreased by 95.2% to 95.78%, and the method has excellent social and economic benefits.
