摘要
随着经济的飞速发展,受到重金属污染的地区越来越多,环境问题也日益突出,特别是铅、镉等常见的重金属元素,对土地造成的污染尤为严重。与微生物修复技术相比,常见的物理化学修复技术易造成二次污染。而微生物修复以污染小、成本低等特点成为热门的重金属土地污染修复技术,越来越受到关注。研究综述了铅、镉污染现状及其微生物修复技术在土壤修复中的应用,包括微生物修复的机理、优缺点及今后的发展方向。
With the rapid development of economy, more and more areas was polluted by heavy metals, and environmental concerns are also increasingly prominent, especially in common materials, such as lead, cadmium, led to heavy soil pollution. The physical and chemical reme- diation technologies compared with bioremediation, are easily to cause secondary pollution, besides, bioremediation with its little pollution and low cost has become a hot land pollution repair technology of heavy metals. This paper reviews lead, cadmium pollution and the application of bioremediation in soil restoration, including the microorganisms repairing mechanisms, advantages and disadvantages, development direction in the future.
