摘要:
針對南水北調配套水庫——北大港水庫水質咸化問題,采用數值模擬方法,應用EFDC 三維水動力水質模型形成水庫水質模擬技術,調控水庫運行方式,提高水庫蓄水利用率.以氯離子為模擬指標,通過實測數據與模擬結果比較分析,驗證了模型的可靠性.將北大港水庫分為主庫區和輔庫區兩部分,利用該模擬技術調控水庫運行方式,對水庫3 種典型蓄供水方案進行水質模擬研究,探討底泥氯離子釋放對水質的影響,指出主輔庫聯合調度為較優的調控方案.該套水庫水質模擬技術可推廣應用于其他南水北調配套水庫.
Abstract:
In view of water salinization of matching reservoir in the South-to-North Water Diversion,the simulation technology of reservoir water quality was developed by numerical simulation method in order to control operation mode of reservoir and improve water quality. Beidagang Reservoir is the regulating reservoir for water supply from Yellow River to Tianjin Diversion and South-to-North Water Diversion. Based on EFDC,the water quality model was applied with chloride as simulation index. Through comparison of simulated and measured data,it was confirmed that the model represented the hydrodynamic and water quality processes reasonably well. Beidagang Reservoir was divided into the main and auxiliary reservoir. Three operating conditions of the reservoir were simulated using the simulation technology. The effect of sediment chloride release on water quality was discussed. The results demonstrate that the operating solution of combining main and auxiliary reservoir is reasonably favorable. It provides reference basis and technical support for water quality safety of Beidagang Reservoir.
