摘要
该文通过在实验室构建小型的水生生态系统，采用水培方法，研究水生植物对富营养化水质的净化效应。发现狐尾藻能有效降低污染水体的浊度，稳定水质，对水体有富氧的效果，同时对调节水体的pH值也有一定作用，能使水体的pH值处于7-8的偏碱的水平，有利于微生物的硝化及反硝化作用的进行。狐尾藻对水中氮、磷营养物质具有较强的吸附能力，试验结果表明，氨氮和总磷的去除效果较好。
Based in the laboratory building the small aquatic ecosystem, purification effect of the eutrophication water by aquatic plants is researched, The results showed that Myriophyllum spicatum L. can effectively reduce the turbidity of pollution water, stabilitate water and enrich oxygen in water, meanwhile they have a certain role on the regulation of water pH, conducively to microbial in nitrification and denitrification process. Myriophyllum spicatum L. is also strong capacity of adsorption to nitrogen and phosphorus nutrient.
