摘要
随着水资源短缺以及环境污染问题的加剧,对污水灌溉的研究越来越受到重视。污水中的氮既是主要营养元素,同时也是重要的污染物质,其运移的机理、影响因素等问题,已成为研究的重点。概述了氮素转化和运移的方式及影响因素、运移规律和模型的研究进展,对存在的问题和发展趋势进行了探讨。
With the aggravating of the shortage sewage irrigation researching had recently been in water resources and the pollution of environment, the paid much more attention. Thus the principles of nitrogen transformation and transportation, as well as their affective factors were become more and more important since that the nitrogen in the sewage were functioning not only as to an organic pollutant, but also a kind of nutrient. Therefore, the advances in researches on the models, routes and factors that affect on the nitrogen transformation and transportation were reviewed and summarized here. Moreover, those problems that had not yet resolved and their trends in researching were discussed as well.
