重金属铬(Cr)的污染及治理研究进展

The Research Progress in Pollution and Control for Heavy Metal Chromium (Cr)

水环境污染和水资源短缺是全球淡水资源正面临的两大问题。也正是水体的污染导致了水资源的短缺,水体中的污染物有很多种类,本文将只对国内地表水中重金属污染物——铬(Cr)的污染及治理进行综述。本论文简要介绍了我国地表水资源现状、地表水中重金属铬的来源、铬污染带来的危害、铬在水中的存在及迁移形式、着重归纳整理了含铬污水的处理方法,对已有的铬污染处理技术应用研究进行综述,对地表水中铬污染治理技术发展进行展望,以供后人研究提供参考资料。

Water pollution and water shortage are major problems for global freshwater resources. It is water pollution led to a shortage of water resources. And there are numerous types of pollutants in water bodies. This article will only review the heavy metal pollutants of surface water—the pollution of chromium. This thesis briefly introduces the present situation of surface water resources in China, the source of heavy metal chromium in surface water, the harm of chromium pollution, the presence and migration form of chromium, mainly summarizes the treatment method of chro-mium-containing wastewater, and overviews the existing chromium pollution treatment technology application, and puts forward my own views, prospects for chromic pollution control technology in surface water.
