藻类去除水体污染物技术研究进展

Research Progress on Removal of Water Pollutants by Algae

随着工业和经济的不断发展,因水土流失、水源污染等因素的影响,水体富营养化以及水体重金属污染不断加剧。水体重金属污染物的主要来源是工业废水,这是因为目前工业排放废水中的重金属含量不断增多,从而导致水体重金属污染加剧,水环境治理成为全球关注的热点环境问题之一。本文比较了水体中氮、磷以及重金属的传统去除方法,综述了藻类去除水体污染物的研究现状及其作用机理,这些综述成果为藻类去除水体中污染物提供了思路。

With the continuous development of industry and economy,due to the influence of soil erosion,water pollution and other factors,the eutrophication of water bodies and the pollution of water and body metals have intensified.The content of heavy metals in industrial wastewater is increasing,resulting in increased metal pollution of water.Water environmental governance has also become one of the hot environmental issues of global concern.In this paper,the traditional removal methods of nitrogen,phosphorus and heavy metals in water are compared.The research status and mechanism of algae removal of water pollutants are reviewed,which provides a new idea for algae to remove pollutants from water.
