人工湿地植物对观赏水中氮磷去除的贡献

Contribution of Constructed Wetland Plants to Removal of Nitrogen and Phosphorus in ornamental Water

选择良好的人工湿地植物对污水中的氮磷去除效果非常显著。通过收集野生植物和园艺栽培植物,构建了观赏水人工湿地实验区,对19种植物的生长活性和对氨氮去除的贡献率进行了分析。结果显示:菖蒲、黄菖蒲、紫露草、芦竹的氮磷积累量超过了平均植物的氮磷积累量,对氮磷去除的贡献率最大。

The removal efficiency of nitrogen and phosphorus in wastewater by choosing good constructed wetland plants is very significant.In this paper,through the collection of wild plants and horticultural plants,the experimental area of ornamental water constructed wetland was constructed.The growth activity and contribution rate of ammonia nitrogen removal of a total of 19 kinds of plants were analyzed.Finally,it was concluded that the accumulation of nitrogen and phosphorus of Acorus calamus,Acorus calamus,Tradescantia and Arundo donax exceeded the average accumulation of nitrogen and phosphorus of plants,and the contribution rate of nitrogen and phosphorus removal was the largest.
