Study on the Estimation of Pollutant Fluxes for Dongliao River Based on Hydrological Periods
摘要
Abstract
Five kinds of popular calculation formulas of pollutant fluxes were applied, to estimate pollutant fluxes based on hydrological periods, taking Sishuang bridge section of Dongliao River as an example. The results show that the CODcr fluxes and the NH3-N fluxes from Sishuang bridge section of Dongliao River was about 3 323.7 and 278. 3 t in 2007. For Dongliao River, the third method that dominated by point source pollution is appropriate to estimate of low-water period, and the estimation of high-water period is suitable for using the fifth method that stress total runoff of period and dominated by non-point source pollution. Besides, the choice of normal-water period' s method will be integrated with the correlation of the quantity and quality of water as well as the relative intensity of rainfall with high-water period and low-water period. Comparing with the five kinds of popular calculation formulas, choosing an appropriate method for the three hydrological periods separately as an estimation of year-long period pollutant fluxes of Dongliao River is more accurate and scientific.关键词
