Abstract:
The pollution characteristics of uranium residue stone in China mainly including:residue stone in the high content of radionuclide,potential harmful of the radiation last for long time,radioactive substances and non-radioactive may cause combined pollution,and maybe accompanied by lixivium pollution and so on.According to China's uranium waste residue of stone pollution characteristic and the harm caused,we put forward that the remediation method are laterite cover,adding phosphorus material and the phytoremediation.The method of laterite cover has well stability to treating uranium hillock,and can achieve the effect of Nitrogen exhalation;phosphorus materials are applied to soil remediation because they are cheap and effective repair agent to heavy metal pollution;phytoremediation is a method that utilizing plant's absorption and enrichment to heavy metal in soil,so that reducing the content of heavy metal in soil,meanwhile,this method has many advantages such as low cost,well recirculation of heavy metal,small damage to repair site and so on.
