摘要
生态调水是通过水资源的合理调配,通过增加水体流动性、利用水质较好的水体提高较差水体的水质,同时增加水体流动性,进而改善调水区域水环境的一种措施。在区域控污、截污的前提下,如具备水源条件,生态调水值得优先选择。以温瑞塘河瑞安段为例,采用一维非定常水动力模型,对不同调水流量、水闸不同运行方式及不同截污率组合条件下的水质改善效果进行了模拟分析,并提出了生态调水控制方案。
Ecological water diversion, which will enhance water self - purification capacity of the river water body through rational water resottrce allocation, is one of water pollution treatment methods. Priority should be given to ecological water diversion if pollution has been controlled in the region and the ecological water demand of the river network is available. Taking the Wenruitang River as an example, this article adopted one - dimensional unsteady hydrodynamic model to simulate the water quality change under different combination of diverted water volume, sluice operation mode and pollution controlling ratio. Based on the above simulation outcomes, recommended solution was put forward eventually.
