石油污染土壤的生物修复研究进展

Advancements of Study on Bioremediation of Petroleum Contaminated Soils

生物修复技术是解决环境污染、恢复被人类活动破坏的生态系统、实现人类社会可持续发展的重要手段之一,它具有速度快、消耗低、效率高、成本低、反应条件温和以及无二次污染等显著优点。本文主要介绍了生物修复的原理和特点,石油污染土壤的各种生物修复技术:微生物修复技术、植物修复技术和菌根根际生物修复技术的研究和应用进展。

Bioremediation is a potential solution to environmental pollutions, to restoration of destroyed ecosystems, and to sustainable development of the society, characterized by being fast in process, low in consumption and cost, high in efficiency, moderate in reaction condition, and free of secondary pollution. An introduction is presented in this paper to principles and characteristics of bioremediation and advancements in researches on and application of various bioremediation techniques to remediation of petroleum contaminated soils, including microbial remediation technologies, phyto-remediation and mycorrhizospheric bioremediation.
