摘　　要：湖泊中的氮磷等营养物质主要来自生活污水、农业废水、化肥等加工过程产生的工业废水,这些污染废水未经处理或处理不达标直接排入湖泊,使水体中营养物质增多,氮磷营养物质超过富营养化发生浓度,易造成湖泊呈现富营养化,促使自养型生物特别是藻类等浮游生物的个体数量迅速增多。本文对水葫芦对水体中氮、磷以及氨氮等营养物质的去除效果,以及覆盖率差异下水葫芦对氮、磷及氨氮的去除规律进行了分析,为探讨水葫芦抑藻机理奠定了基础。The nitrogen and phosphorus nutrients in lakes mainly come from industrial wastewater generated during the processing of domestic sewage,agricultural wastewater and fertilizers.These polluted wastewater are directly discharged into the lake without treatment or do not meet the standards,causing an increase in nutrients in the lake water.If the nitrogen and phosphorus nutrients discharge into the lake water exceeding the concentration of eutrophication,it is easy to cause eutrophication in the lake,promoting the vigorous growth of autotrophic organisms,especially,the number of individual plankton such as algae is rapidly increasing.The removal effected of water hyacinth on nutrients such as nitrogen,phosphorus,and ammonia nitrogen in water,as well as the difference in coverage rate,were analyzed.The removal law of nitrogen,phosphorus and ammonia nitrogen by water hyacinth laid a foundation for exploring the mechanism of water hyacinth inhibiting algae.
