摘要
地下水中三氮(氨氮、亚硝酸盐氮和硝酸盐氮)污染正日益受到国内外研究者的关注,关于三氮污染物的迁移规律许多研究者做了大量的工作,并取得了较好的研究成果,推动了三氮污染物防治研究工作的进展。本文在已有研究的基础上首先介绍了三氮在地下水中的运移转化机理,然后分析了当前研究常用的方法即定性实验方法和定量数值模型方法,最后提出了研究中存在的问题和三氮污染防治建议,为以后的治理三氮污染提供技术支持和理论基础。
The three forms of nitrogen(ammonia nitrogen,nitrite nitrogen and nitrate nitrogen)contaminant are paid more and more attention to the researchers at home and abroad.Many researchers did a lot of work about the three forms of nitrogen transport and transform,and got a lot of good research results,which promoted the research progress of nitrogen contaminant preventive treatment.In this paper on the basis of existing researches,the authors first introduce the transport and transform mechanism of three forms of nitrogen in the groundwater,and then analyze commonly used research methods(that are the qualitative experimental method and the quantitative numerical model method)in the present study.Finally the authors put forward some existing problems and some suggestions about nitrogen contaminant preventive treatment,which will provide technical support and theoretical basis for the nitrogen contaminant prevention.
