Numerical Simulation Analysis Of Water Quality Of Nanfeihe River From Dongpu Reservoir To Dang Tu Bridge

Nanfeihe rivers is a usually upstream runoff water shortage in the rivers, is also the biggest tributaries into chaohu lake. With the rapid development of Hefei’s rapid economic development and rapid population growth and industrialization, Nanfeihe rivers by serious pollution, and the ecological environment from damage. Nanfeihe pollution problem has seriously hampered the Hefei Economic sustainability.Study the environmental problems Nanfeihe river, find the appropriate Nanfeihe river of the water quality model, Nanfeihe river pollutant dispersion migration of the forecast, pollution and pollution control comprehensive control chaohu lake has important significance.First This paper were evaluated Nanfeihe water quality by a coupled model analysis and triangular fuzzy numbers based on entropy weight sets.then This paper has studied the of major parameters of introduced models. Finally Dongpu Reservoir water transfer schemes is designed COD pollutant as a pollutant index, mainstream sector in the model, numerical simulation of different water transfer schemes improve Nanfeihe the effect of water quality, and program, the results of sciencedevelopment of environmental protection measures Nanfeihe water to provide relevant scientific basis.
