Abstract

The invention discloses an underground water pollutant tracing method based on numerical simulation, and belongs to the technical field of underground water treatment. The invention is technically characterized by comprising the following processing steps of modeling, starting point determination, verification, updating and inspection output. The method comprises the following steps: constructing a grid region model of underground water in advance; determining a traceability starting point grid according to the flow direction of underground water; locating the grid where the source tracing starting point and inspecting the adjacent grid to obtain the potential pollution grid of the underground water pollutants, and then obtaining the potential pollution path of the underground water pollutants, which is very beneficial to the treatment of underground water pollution. According to the method, whether the potential pollution combination exists in the grid adjacent to the grid where the source tracing starting point is located or not is judged, so that the multiple potential pollution paths of the pollutants are detected, and the detection and analysis precision of the potential pollution paths of the pollutants is improved.

Description

technical field [0001] The invention relates to the field of groundwater treatment, in particular to a numerical simulation-based traceability method for pollutants in groundwater. Background technique [0002] Due to the strong concealment and suddenness of groundwater pollution, it is often difficult to determine the source of pollutants when pollution is discovered. Rapid identification of the location of pollution sources has important research value for groundwater restoration and control and formulation of prevention and control measures. Traceability of groundwater pollutants (groundwater pollution source analysis) is to find out the location of pollution sources and the history of pollutant migration and transformation through limited observation data, which is the first step in groundwater pollution control. [0003] The time and place of sudden groundwater pollution accidents have great uncertainty, and it is also difficult to determine the way and degree of harm, ...
