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.
