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.
