摘要: 为了解铁岭市中心城区降雨形成径流后氨氮污染特征,选取城区内2个典型排污沟为研究对象,采用野外采样与室内分析相结合的方法,利用2005年7月的一场降雨过程实测降雨数据,对氨氮浓度进行对比分析。结果表明:在降雨初期,铁岭市中心城区降雨径流中氨氮浓度迅速上升,并很快达到峰值。随着降雨历时的延长,氨氮浓度逐渐下降并趋于稳定。

Abstract: In order to know the NH3-N pollution characteristics of the rainfall runoff in Tieling,two typical pollutants ditches were selected in this paper.And the concentrations of NH3-N were analyzed based on the rainfall data in July,2005.The results indicated that the NH3-N concentrations of the rainfall runoff increased in the initial stages of rainfall,and it reached the peak value rapidly.But the concentrations of NH3-N decreased gradually and became stable with the increase of rainfall time.
