地下水硝酸盐生物处理技术研究进展

The Progress of Bioremediation for Removal Nitrate from Groundwater

生物处理技术具有高效、低耗的特点,在地下水硝酸盐处理过程中有着广泛的应用前景。简要阐述了硫自养反硝化、氢自养反硝化以及异养反硝化的原理,概述了近些年来国内外地下水硝酸盐生物处理技术的研究现状,指出了不同生物处理技术存在的主要问题及其解决途径。最后指出了地下水硝酸盐生物处理技术需深入研究的内容,同时展望了以后的发展前景。

Bioremediation is a promising technique for removing nitrogen from ground water because of its efficiency and moderate cost.The principles of sulfur-autotrophic denitrification,hydrogen-autotrophic denitrification and heterotrophic denitrification are briefly presented.The current research status of biological denitrification technologies is summarized,and the solutions to the existing problems are provided.Based on these,the future research directions in this field are put forward and trends are prospected in this paper.
