| 摘 要： | 综述近年来国内外利用水生植物修复富营养化水体的研究成果,将植物对富营养化水体的净化机理,归纳为两方面∶植物能够提供碳源促进反硝化作用和植物与微生物的协同作用以及湿地酶的作用,植物本身的同化作用仅占全部作用的很小一部分,约为2%~5%。在此基础上讨论了影响植物去除氮、磷的因素和植物修复技术的优点及不足之处。

| Abstract: | Phytoremediation is a promising new technology that utilizes plants to degrade,assimilate,metabolize or detoxify contaminants in the environment.The latest research achievement in both home and abroad on phytoremediation of eutrophicated water is summarized.There are several mechanisms of macrophytes in promoting nutrients removal,namely: providing carbon resources for denitrification;cooperative effect of plants and bacteria and the effect of related wetland enzyme promoting nutrients removal.Assimilation only makes 2%~5% contribution to total reduction.On the basis of the mechanisms of nutrients removal,the effect of phytoremediation are associated with different species of plants,the extent of eutrophication,morphologyof nitrogen,the culturing type(monoculture or polyculture),etc.Both advantages and disadvantages of applying this technology into practice are discussed. |
