Embodiment

[0069] (1) Site data collection and reduction coefficient calculation

[0070] ①Data collection

[0071] A total of 10 typical sites in 7 industries related data were collected, namely: a landfill in Beijing, Xinjiang A power plant, a glass factory in Wujiang, a science and technology company in Hunan, a mine in Xiamen, an open-pit coal mine in Henan, a coal company in Shanxi, a paper mill in Shandong, a hazardous waste disposal site in Liaoning, and a hazardous waste disposal site in Changsha. The numbers 1, 2, 3, ..., 10 are used below to refer to 10 venues. For the relevant parameters of the pollution source and the vadose zone of the site, see Table 1 with Table 2 .

Abstract

The invention discloses a strong quantitative evaluation method for an underground water pollution source. The method comprises the following steps: collecting site information, simulating the concentration of a pollutant in the pollution source when reaching an underground water interface by HYDRUS-1D software, and calculating a reduction coefficient; carrying out strong master control factor screening of the underground water pollution source of the site by a grey correlation analysis method; building a multivariate linear regression equation through the screened strong master control factors of the underground water pollution source, and carrying out model checking and error evaluation; and carrying out a strong quantitative evaluation on the underground water pollution source of the site with limited information by the built multivariate linear regression equation. According to the method disclosed by the invention, a strong quantitative evaluation task of the underground water pollution source of the site with limited information can be effectively solved; a technical reference is provided for investigation and restoration of a pollution site; and the strong quantitative evaluation method is simpler than an HYDRUS-1D software simulation in input conditions, and is similar to an HYDRUS-1D software simulation result in output.

Description

technical field [0001] The invention relates to the field of water environment protection, and more specifically relates to a method for intensive quantitative evaluation of groundwater pollution sources, which can effectively solve the task of intensive quantitative evaluation of groundwater pollution sources in sites with limited data, and provide technical reference for investigation and restoration of polluted sites. Background technique [0002] When surface pollutants infiltrate and pass through the vadose zone, a series of physical, chemical and biological reactions such as dissolution, adsorption, and desorption will occur, so that the structure, composition, and concentration of pollutants when they reach the underground aquifer are quite different from those at the beginning of infiltration. . According to the relevant national environmental management regulations, the concentration of groundwater pollutants is a key indicator for judging whether the groundwater qu...
