摘要
对福州市四个自来水水源中含氮化合物含量的分析,发现总氮、氨氮在一年中变化规律有二个峰值:分别与丰水期农田水土流失引起面源氮的补给和与枯水期水流量小,生活污水、畜禽养殖污水的排入得不到稀释有关;测得四水源中水中溶解氧含量均较高,故可不考虑水中亚硝酸盐氮对身体健康的危害;不同水源地总氮、氨氮含量悬殊较大,说明水厂水质受城市生活污水无处理排放的影响较大。此外还与闽江水源受潮汐影响有关。
Analysing the nitrogen chemical compounds in the four sources of running water in Fuzhou.Two peak values in the annual change of the total nitrogen and ammonia nitrogen were found .They were conneted with the period of water resources. The farmland′s water and soil erosion lead to the surface nitrogen to the water in the rich water season and the domestic sewage and the breed sewage of domestic animals and flows can not be diluted in the dry season. However the dissolved oxygen in the four sources of water ...
