摘要
对东阳江流域的干流及主要支流进行了高密度监测,分析了东阳江流域氨氮污染的特征,并进行东阳江干流氨氮水环境容量的计算。结果表明:东阳江流域的氨氮污染来源有显著的地域特色,干流枯水期的氨氮浓度要大大高于丰、平水期的浓度,基于WASP7.3模型计算的东阳江氨氮全年平均(50%保证率)和枯水期(90%保证率)的环境容量分别为732.7t/a、1447.7t/a。
The Ammonia nitrogen （ NH3 - N） was high - intensity monitored in the main stream and the tributaries of Dongyang River. According to the results, the characteristics of NH3 - N concentrations were analyzed in differ-ent seasons and sections of Dongyang River. The results showed that the sources of ammonia nitrogen were different in districts. The concentration of NH3 - N in low flow season was higher than that of normal flow season and high flow season. The Water Environment Capacity （ WEC） of NH3 - N was simulated by WASP7. 3software. The value of WEC was about 732. 7t/a at 50% probability of flow and 1447. 7t/a at 90% probability of flow.
