摘要
本项目以福州西湖沉淀区水体治理为目标,从水体水动力和水质模型建模入手,根据西湖-左海地形图,将西湖湖区概化为14361个网格节点,对于截污控源工程措施,考虑到污染物在沉淀区的停留时间较短,水质模型采用AD模型。由于截污措施均在研究区域外,整体表现为对屏西河入流水质的影响,因此对截污前后入流水质的变化进行评估模拟。通过模拟发现,采取截污措施后,对于减少COD、NH3N污染物贡献较为明显,对于减少SS污染物有一定成效。
This project takes the water body treatment in the sedimentation area of Fuzhou West Lake as the goal,starts with the modeling of water body hydrodynamic and water quality models,and generalizes the West Lake area into 14361 grid nodes according to the West Lake Zuohai topographic map.For the measures of pollution interception and source control,considering the short residence time of pollutants in the sedimentation area,the AD model is used for the water quality model.Since the sewage interception measures are all outside the study area,and the overall performance is the impact on the inflow water quality of Pingxi River,the changes of inflow water quality before and after the sewage interception are evaluated and simulated.Through simulation,it is found that after the sewage interception measures are taken,the contribution to the reduction of COD and NH3N pollutants is more obvious,and the reduction of SS pollutants has some effect.
