“就地”生物治理技术

On-site Biological Treatment Techniques

土壤正受到日益严重的有毒有害有机污染物的危害,国外从80年代中期开始研究“就地”生物治理技术,并完成了一些实际工程。根据文献资料详细介绍了这种新兴环境生物技术的研究概况,综述了固有生物净化过程的4种强化措施:接种微生物、添加营养盐、提供电子受体、提供共代谢底物诱导共代酶。同时,阐述了“就地”生物治理的工程化手段和评价“就地”生物治理技术可行性的程序,并列举了几个技术应用的例子。

The biological treatment technique is an innovative method which utilizes microbial technique and environmental engineering measures and applies to treatment of toxic and hazardous organic pollutants in soil, ground water and oceans on site. This paper introduced the outline of this new technique and reviewed the ways to enhance natural biodegradation process, and the engineering methods apply to biological treatment technique and procedure to evaluate the feasibility of biological treatment technique. Then several case studies were also listed.
