The summary of hydrophytes on removal of nitrogen and phosphorus in eutrophic water

Water eutrophication caused by high concentration of nitrogen and phosphorus was one of environmental problems in domestic and foreign countries.Aquatic plants which are the important carries of removal of nitrogen and phosphorus can improve the purification efficiency in eutrophic water.This paper introduces briefly the determination methods,the type of aquatic plants and its influence factors on the N,P removal including the type and dosage of aquatic plants,different organ,eutrophication,N/P ratios,cultivation and combination mode,ecological models construction,the change of season and water temperature and microbial action.
