内河涌氨氮污染的特征及其来源的研究

以佛山市雅瑶涌为研究实例,探讨了珠江三角洲河网地区围内河涌氨氮污染的特征,并对氨氮的来源进行了研究。内河涌的氨氮污染逐年严重,并呈现季节性的变化,已成为最主要的污染因子。研究结果表明,畜牧水产业和非点源都是比较显著的氨氮污染源,但未经集中式污水处理厂处理的生活污水,则成为内河涌最重要的氨氮污染源。

Research on the Characteristic and the Source of Ammonia Nitrogen in Inner-river

In this paper,the characteristic and the source of ammonia nitrogen are studied in Yayao river,which is a typical inner river in the Pearl Delta Area.The pollution of ammonia nitrogen is serious year by year in inner-river and becomes the main pollution factor though its concentration varies with different seasons.In general,stock raising,aquaculture and non-point source are the reasons for ammonia nitrogen pollution in inner-rivers whereas the sewage which isn't treated is the key pollutant source.
