摘要
土壤是人类生活的必要物质基础,一旦受到污染,将会对其它圈层产生危害。土壤的重金属污染中,铬污染非常普遍。随着铬化工行业的发展,铬造成的土壤污染问题越来越严重。本文概述了铬污染的来源,铬的存在形态及危害,介绍了铬污染土壤的4种修复方法,并展望了当前土壤铬污染治理的发展趋势,为科学合理地处理土壤修复问题提供了方向。
Soil is a necessary material foundation of human life. Once contaminated, it will cause harm to other spheres. Between the soil pollution of heavy metals, the chromium pollution are very common. With the development of chemical industry of chromium, chromium pollution problems of soil are becoming more and more serious. This paper summarized the chromium pollution sources, chromium existence forms and hazards. Meanwhile, 5 remediation technics were introduced. It forecasted the developing trend of the treatment of chromium contaminated soil and provided a direction for the reasonable treatment of chromium contaminated soil.
