| 摘 要： | 简要论述了人工湿地生态系统氮转化的几种主要影响因素.进行了人工湿地植物的选择、不同的进水方式对提高大气复氧的研究和增加湿地系统碱度的措施等方面的讨论.从碱度方面分析,提出了分步硝化、反硝化的设计构想,并做了简单的论述,同时在增加反硝化碳源的问题上设想了两种新的方案.最后,针对我国小城镇以及广大农村地区的排水特点和我国的地形特征提出了在具有一定坡度的地形上建立小型"分散式"人工湿地的建议.

| Abstract: | Several main influencing factors of nitrogen transformation in the artificial wetland ecosystem were introduced briefly. Several problems, such as the selection of artificial wetland vegetation, the influence of different water intake ways on the improvement of reaeration, and the measures for the increase of alkalinity of wetland system, were discussed, too. From the aspect of alkalinity analysis, this paper proposed and expounded the design idea of step-nitrification and denitrification. At the same time, two new pro- grams for the issue of increasing denitrification carbon were put forward. In the end, based on the characteristic of drainage in little towns and rural areas of China, combined with the topographical features of China, the suggestion of constructing dispersive small-scale artificial wetland in the areas with small slope was put forward. |
