人工湿地脱除富营养化水体氮磷的研究进展

水体中氮磷营养物质不断积累,部分藻类及水生生物的过度繁殖,导致了水体的富营养化。水体富营养化防治的关键是减小水中氮、磷的含量。人工湿地是一项新型的废水处理技术,近年来在脱除富营养化水体氮磷中获得广泛研究和应用。本文在简述脱氮除磷机理的基础上,较系统地阐述了影响人工湿地脱除氮磷的因素及工艺的在改善水体富营养化的研究进展,以便在构建人工湿地中对各项因素综合考虑及兼顾利用,提高人工湿地修复富营养化水体的综合效能。

Progress on Nitrogen and Phosphorus Removalin Eutrophic Water Body by Constructed Wetland

The water eutrophication is caused by the incessant accumulation of nitrogen and phosphorus in water and excessive propagation of a few of algal and hydrobios.The key point for the pollution control of eutrophication of the Water Body is to reduce the content of nitrogen and phosphorus in water.Constructed wetlands,as a new kind of wastewater treatment technology,are widely studied and used in Nitrogen and Phosphorus removal.This paper systematically described the progress on the Nitrogen and Phosphorus removal in eutrophic water body by constructed wetland basing on the mechanism of Nitrogen and Phosphorus removal.The aim was to facilitate using all kinds of influencing factors to enhance comprehensive efficiency of constructed wetlands in repairing eutrophic water body.
