难降解氯代有机物污染环境的生物修复技术研究进展

氯代有机物是一类在生产和生活中广泛应用并被大量排放到环境中的难降解有机污染物质,一旦进入生态环境,就会在水体、土壤和底质中长期残留,并在食物链中不断积累、富集,从而对生物体产生危害。因此,对受这类难降解有机物污染的环境修复是目前所迫切需要解决的环境问题之一。基于物理和化学修复方法成本较高易造成二次污染,文中探讨了国内外生物修复技术的研究进展,并对难降解氯代有机物污染环境修复的研究方向进行了展望,由于环境中的污染物质复杂多变,联合生物修复技术将成为未来的研究热点。

Review on the Bioremediation of Environment Polluted by Hard Degradable Chlorinated Organics

Chlorinated organics are highly toxic and carcinogenic,and can remain in the environment for a long time,due to their stability and capacity for bioaccumulation.Since chlorinated organics are widely used in a number of different industrial processes,there is a need to develop safe and effective remediation methods for removing chlorinated compounds in the environment.Physical and chemical methods have been well studied all over the world,but they had some limitations,such as high cost and existing secondary...
