- Abstract:
- The comprehensive environmental protection of urban water system is the key to improve its ecological environment. To solve the failure of overflow weir caused by the high water level of 9 branch channels flowing into Nanshelang and Dazhenpu drainage channels in Nanshelang-Dazhenpu drainage district of Dongguan Ecological Park, a MIKE11 one-dimensional hydrodynamic and water quality coupling model was constructed to investigate the impact of transforming weir to sluice gate scheme on water quantity and quality of Nanshelang and Dazhenpu drainage channels. After the implementation of the scheme, the pollution load was reduced, and the water environment of Dongguan Ecological Park was effectively improved. The reduction rates of COD, ammonia nitrogen and total phosphorus of Nanshelang drainage channel were 58.4%, 51.5% and 46.4%, and those of Dazhenpu drainage channel were 51.2%, 48.8% and 42.3%. This paper provided another option for the treatment of polluted rivers in high?density development areas.
