摘要:以淮安市盱眙县经济开发区的地下水为例研究COD迁移规律。大量生活污水和工业废水污染渠河水质,并对地下水水质污染严重。因此为研究区域周边地下水的污染情况,利用地下水流动模型Visual Modflow和运移模型MT3DMS,采用三文数学模型预测未来20年研究区内污染物COD的迁移过程。根据模拟分析结果显示,在潜水含水层中,COD迁移的速度较慢,而降解相对略快。目前对淮安市地下水水质影响不大,但为了限制污染程度的不断扩大,应及时处理污染源。29687 毕业论文关键词:地下水;Visual Modflow;COD;迁移规律
Study on COD Groundwater Migration Law in Xuyi County Economic Development Zone
A Case Study of Waste Mineral Oil Project
Abstract:Taking the groundwater of Xuyi County Economic Development Zone in Huai'an as an example to study the COD migration law. A large number of domestic sewage and industrial wastewater pollution Drainage River water quality, and groundwater quality caused serious pollution. In order to study the pollution situation of groundwater in the surrounding area, the three-dimensional mathematical model was used to predict the COD migration process of pollutants in the study area in the next 20 years using the groundwater flow model Visual Modflow and the migration model MT3DMS. According to the results of the simulation analysis, in the ping aquifer, COD migration is slower, and the degradation is relatively slightly faster. Huainan City, the current impact of groundwater quality is not, but in order to limit the degree of pollution continues to expand, should promptly deal with pollution sources.
