水生植物对富营养化水体除磷去氮的研究概述

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

水体富营养化是很多国家面临的水环境问题之一,水中氮磷浓度过高是引起水体富营养化的重要原因,而水生植物是水体氮磷去除的重要载体,可以提高水体净化的效率.对水生植物累积氮磷的测定方法,水生植物类型及影响水生植物氮磷去除的因素(包括水生植物的种类、用量、不同器官、富营养化程度、氮磷比例、培养和组合方式、生态模式构建、季节变迁、水体温度变化及微生物作用等)进行了概括.

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.
