Description

technical field [0001] The invention relates to a method for optimizing the hydraulic interception scheme of groundwater pollutants, specifically a method for optimizing the design of the hydraulic interception scheme by using orthogonal design and groundwater numerical simulation software GMS (Groundwater Modeling System). technical background [0002] Groundwater resources occupy a pivotal position in our country's water resources. Because of their wide distribution, good water quality, strong regulation and storage capacity, and high degree of water supply assurance, groundwater resources are being developed and utilized more and more widely. However, with the development of society and economy, massive discharge of industrial waste water, agricultural pollutants, intensive livestock and poultry breeding, excessive use of nitrogen fertilizer, arbitrary discharge of urban domestic waste, and disorderly development of groundwater have gradually caused groundwater to be affec...
