富营养化水体中的氮磷及其去除研究

由于工业废水和生活污水的排出量不断增加,氮磷和有机物的不断泄入,致使湖泊、水库水体日趋恶化,藻类大量繁殖、色度增高、透明度下降、耗氧量上升,水体发臭。氮磷在水体中的浓度超标造成水体的富营养化已经成为一个全球性的问题。以这样的水作为淡水水源,通过常规处理难以达到日益提高的饮用水卫生标准。因此分析氮磷在自然水体中的形态及其作用机理,制定合理有效的水体中氮磷的去除和控制的方法显得尤为重要。

Studies on Removal of N and P in Eutrophic Water Bodies

With the constant increase of the industrial and domestic sewage discharge, nitrogen, phosphorus and organic substances have kept going into the lake, reservoir and other water bodies, worsening the water quality, thriving the growth of algae, darkening the color, lessening transparency, raising the oxygen consumption and making the water body stinky. Water body eutrophication due to high concentration of N and P is now a global problem, making it difficult to meet the standard for potable water through normal treatment, so a rational and efficient way to remove N and P from water is especially important.
