【 摘 要 】

Developing a water quality model which is based on FORTRAN to simulate the distribution of pollutant concentration after water pollution accidents and to apply it to the drinking water source area of Heshangshan is the intention of this research. Taking ammonia nitrogen as the main water environment index, the spatial and temporal distribution and flow rate of pollutants at the inlet of Heshangshan drinking water source were analysed, and compared with those before and after the dispatching. The upstream discharge of water source area is selected from dry period, fall period, flood season and storage period respectively. The results show that the influent pollutant concentration decreases gradually with the increase of upstream flow in the source area. Moreover, the higher the upstream flow rate, the faster the decrease of influent concentration and the easier to reach level III.
