土壤重金属镉修复技术研究进展

Research Progress on Remediation Technology on Soil Heavy Metal of Cadmium in Soil

随着城市化工业化的快速发展,土壤污染问题日益严重;土壤重金属污染来源广泛、危害严重,重金属污染修复已成为当前环境科学研究热点。镉因其难降解、易富集、毒性高等备受关注。为了减轻镉污染带来的危害,众多研究人员开展了大量的镉污染土壤修复技术研究,本文简述了各种修复土壤镉污染技术的原理、实用性及其国内外研究与发展动态,进一步提出对未来镉污染土壤修复技术有待深入研究的有关问题,并对修复技术进行了展望。

With the rapid development of urbanization and industrialization in China, the soil pollution is becoming more and more serious, the heavy metal pollution of soil, which has wide range of source and serious endanger, has become a popular questions in environmental pollution control. Cadmium is of great concern because of its difficult degradation, easy enrichment and high toxicity. In order to alleviate the harm caused by cadmium pollution, researchers have carried out a lot of cadmium contaminated soil remediation technology research. Focusing on introducing the principle, practicality and the development of the soil cadmium pollution technology, the development of soil cadmium pollution technology on the future was further discussed and forecasted.
