土壤污染的生物修复技术研究进展

Progress in Bioremediation Technology of the Polluted Soil

土壤污染是当今面临的一个重要环境问题。常规的土壤污染治理技术,如物理及化学治理技术,由于其技术要求高或经济成本昂贵,对土壤结构的扰动破坏严重,因而对其大规模的推广应用存在较大问题。而生物修复技术已被证明是一项非常有应用前景的新技术,成为土壤污染治理研究领域的一个热点。本文综述了近年来有机物及重金属土壤污染的生物修复机理和研究进展,并对其治理技术的最新研究动态、存在问题及发展趋势做了初步的讨论。

Due to their high implementing costs,strict technical demands and probably serious damage on soil texture,conventional ways are difficult to be selected for contaminated soil remediation on a large scale.Bioremediation technique has been proved to be an extensive prospect for use in contaminated soil remediation and becomes a research focus in the field.In the paper,the mechanisms and research advances in bioremediation on the organic and heavy metal contaminated soils were reviewed.And the latest development,disadvantages and trends of the bioremediation technique were also preliminarily discussed.
