Abstract In this study, correlation analysis and nonlinear fitting were adopted to explore the migration and transformation of nitrogen pollutants during dry and wet depositions of roof rainwater based on data collected from 15rainfall events for one year. The results show a significant correlation between the load reduction of all nitrogen pollutants in the process of wet deposition and runoff.However, no strong correlation was observed between rainfall intensity and COD, especially in the early rainfall period. An analysis of the first flush effect of nitrogen pollutants found that all, except TON, had a weak first flush phenomenon, and the wash-off intensity of the wet deposition varied as follows: NO₃^--N>NH₄⁺-N> NO₂^--N>TON, whereas that in the runoff varied as NO₃^--N> NO₂^--N >NH₄⁺-N >TON. In addition, the average TN contribution rates of dry and wet depositions to roof runoff were 23.7% and 76.3%, respectively, among which the NH₄⁺-N comprehensive proportion was the highest, exceeding than 50%. Overall, the characteristics of dry and wet depositions and migration of nitrogen pollutants in roof rainwater were systematically elucidatred in this study, which can provide a reference for the formulation of urban roof runoff pollution control measures.

Key words： roof runoff dry deposition wet deposition first flush nitrogen pollution
