重金屬污染土壤生物修復(fù)技術(shù)研究進(jìn)展
摘要 重金屬污染土壤修復(fù)技術(shù)是世界性難題。闡述了近年來(lái)國(guó)內(nèi)外涌現(xiàn)出的重金屬污染土壤的生物修復(fù)技術(shù),如植物修復(fù)技術(shù)、動(dòng)物修復(fù)技術(shù)、微生物修復(fù)技術(shù)及聯(lián)合修復(fù)技術(shù)等,分析了各種生物修復(fù)技術(shù)的優(yōu)缺點(diǎn),并對(duì)今后重金屬污染土壤生物修復(fù)技術(shù)的研究提出展望。

Abstract The remediation of heavy metal contaminated soil is a worldwide problem. Bioremediation technology emerged in recent years for heavy-metal contaminated soil is reviewed, including phytoremediation,animal remediation,micro-remediation and associated remediation. The advantages and disadvantages in soil bioremediation technology were analyzed. The prospect of soil bioremediation technology was put forward.
Key words Heavy metal;Contaminated soil;Bioremediation technique
