水面浮萍对水体富营养化的自净作用研究进展

The progress in research of water self purification of duckweed to eutrophication

利用浮萍类水生植物对富营养化水体进行自净作用,不仅仅能大量去除水体中的氮、磷等营养物质,还可以将回收的浮萍加工成为饲料和肥料或者工业原料,实现资源的回收利用,是一种最为经济有效以及易于推广的水污染治理技术。本文从富营养化的起因和控制措施、浮萍净化水体的优势以及国内外浮萍净化水体研究进展等方面讨论,并总结了目前浮萍研究现状,同时展望了未来的研究方向。

The duckweed aquatic plants to the eutrophic water body self purification effect,not only can remove a lot of water,nitrogen,phosphorus and other nutrients,can also be recycled duckweed processing into feed and fertilizer or industrial raw materials,to achieve recycling of resources,is one of the most economical and effective and easy to promote water pollution control technology. This paper from the eutrophication of the causes and control measures,duckweed purification water advantage at home and abroad as well as duckweed research progress of water purification,discussion and summary of the present research status of duckweed,and the future research directions are suggested.
