Abstract
In view of the impact of non-point source pollution on the quality of water environment, the campus area of Shenyang Jianzhu University was taken as the research object, and the empirical model---SCS runoff curve number method is used to estimate the annual load of different runoff pollutants generated on the underlying surface of the roof and the underlying surface of the pavement. The results show that the load TSS of annual runoff pollutants in the campus is 38,975.66 kg/a, COD is 10,102.12 kg/a, TN is 454.78 kg/a, TP is 49.1 kg/a, and NH3-N is 171.88 kg/a; In 2015, the annual runoff pollutant TSS loading was 38189.14kg/a, COD was 19293.5kg/a, TN was 833.68kg/a, TP was 77.59kg/a, and NH3-N was 567.89kg/a.
