摘要:
城市水系的环境综合治理是改善生态的关键，以东莞市生态园南畲朗-大圳埔排水分区为例，针对汇入南畲朗、大圳埔排渠的9 条支渠运行水位较高导致溢流堰失效的问题，构建MIKE11一维水动力水质耦合模型，研究了撤堰改闸方案对南畲朗、大圳埔排渠水量水质的影响。结果表明，撤堰改闸方案实施后，可以减少污染负荷，并能有效改善东莞生态园的水环境，其中南畲朗排渠COD削减率为58.4%、氨氮削减率为51.5%、总磷削减率为46.4%；大圳埔排渠COD削减率为51.2%、氨氮削减率为48.8%、总磷削减率为42.3%，这为高密度开发区域污染河道的治理提供了思路。
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.
