- Abstract:
- Chemical oxygen demand, ammonia nitrogen, dissolved oxygen, chromium and cooper have been chosen as pollution indices in this research. In this typical rainfall in NeiJiang urban area, the characteristics of nonpoint source of surface runoff formed in five distinct ways of land utilization including land for mining, commerce, residence, traffic and construction was simulated by SCS rainfall model. The results revealed in a typical rainfall of urban district the pollution load thickness of those five elements above were 37.20, 0.67, 3.72, 0.01, 0.03 mg/L, respectively. Sums of pollution load were 2 361.08, 35.20, 197.57, 1.47, 1.28 kg, respectively. As for the five different ways of land utilization, the COD pollution load contained in mining land was 12.49%, 66.56% in commercial land, 4.52% in residential land, and 13.27% in traffic land and 3.16% and in construction land. Pollution load of ammonia nitrogen was 17.35%, 41.25%, 15.03%, 14.90%, 11.47%, respectively, and pollution load of dissolved oxygen was 20.25%, 37.93%, 23.85%, 10.11%, 7.86% in the above different types of lands. Moreover, the pollution load of the other two elements including chromium and cooper in those lands were 8.57%, 76.36%, 3.88%, 7.75%, 3.40% and 21.95%, 21.95%, 10.39%, 39.84%, 5.86%, respectively. As a result, we figured out that the nonpoint source produced in the land for commerce take up largest proportion in a typical rainfall and COD was 66.56%, ammonia nitrogen was 41.25%, dissolved oxygen was 37.93%, chromium was 76.36% and cooper was 21.95%. Finally, we summarized that rainfall runoff would pollute the rivers, lakes and the estuaries which we investigated, either in the short term or long term.
