长江江苏段区域供水水源地水质可达性研究

Reaching function analysis of water quality in large water supply planning in the Yangtze River in Jiangsu province

  • 摘要: 采用平面水流、水质有限体积法及黎曼近似解模型,在无结构网格上对偏微分方程进行有限体积法的积分分离散,模型具备有限单元法及有限体积法两者的优点。采用同步遥感、水量、水质实测资料对模型进行了率定验证,在对长江水源地、沿江污染源调查以及岸线稳定段分析结果基础上,进行污染源概化以及确定主要研究江段。在对概化的污染源计算出在设计条件下的污染带分布图,并计算出污染带长、宽随排污量变化曲线;在上述研究基础上,分析出长江各水源地及岸线稳定段的水质变化状况。对长江江苏段各主要排污口的污染带进行了计算,并对长江江苏段区域供水水源地的水质可达性进行了研究。

     

    Abstract: This paper presents a two-dimensional unsteady flow model(RBFVM22D),which is based on the finite volume method combined with unstructured triangle and quadrilateral grids in the Yangtze River in Jiangsu province.The simultaneous hydrodynamic,water quality and remote sensing data are used to calibrate and verify the model.The results agreed well with the field data.Based on the investigation of the water quality,pollution sources and stability of the river bank,the main pollutant mixed belts in generalized pollutint and the relationship between the area of the belts and the discharged pollutants are computed.The water quality situation in the water supply place is analyzed and the suitable pollution control measure is given.
