摘　　要：我国耕地资源极其匮乏,土壤污染形势严峻。针对铀矿区污染土壤修复和铀资源化研究国际上尚未见报道,本文在对721铀矿尾矿坝周边环境及污染区自然生长植物对铀的富集能力深入调研后,探讨了一套以植物修复为主,客土覆盖为辅的土壤修复方法,并结合当今生态农村建设所提倡的循环经济理论(减排、资源化、再利用的"3R"),提出对富集后植物收割后集中降解,将其转化为绿色能源,采用特效吸附材料对铀资源进行回收的综合治理方案。通过对铀污染土壤中铀的提取,同时实现土壤修复与铀的资源化,为我国铀矿尾矿坝周边污染土壤绿色修复与铀资源化奠定基础。Chinab cultivatable land is extremely scarce, soil pollution situation in China is of grim prospect. Researches on rehabilitation d contaminated soil in uranium mines have not been seen. In this study ,after an in - depth review of resear-ches on the Uranium enrichment capability of the plants grown in the area where the Uranium mine named 721 dumps its tailings,a set of remedies for polluted soil are proposed. The remedles,comblned with methane fermentation technology, which is popular in today＇ s rural ecological development,are comprehensive treatments of polluted soil. key features of the proposed remedies include： Uranium enrichment by plants first, then comes the harvest and decomposing processes with which green energy can be yielded,tben a customized sorbent is employed to recover Uranium. By extracting uranium from contaminated soil,this method,which has the advantages of rehabilitating polluted soil and maximizing the use of scarce U- ranium resources over traditional ones,can throw new light on both tailing treatment and recovery of Uranium in Uranium mines in China.
