Embodiment 1

[0046] Such as figure 1 As shown, a pollution identification and analysis method for groundwater environment, including the following steps:

[0047] Step 1: Based on the daily groundwater inspection, maintenance and water quality monitoring of the site, compare the monitoring wells where the pollutants were found in the work with the devices on the site, and find out the devices with the same characteristics as the found pollutants;

[0048] Step 2: Distinguish the devices with the same characteristics as the pollutants found in step 1 according to the upstream and downstream of the groundwater flow field of the site where the monitoring well where the pollutant was found, and exclude the downstream of the monitoring well and the found pollutant. devices with the same characteristics of pollutants;

[0049] Step 3: Calculate the time period T for the pollutants to reach the monitoring well where the pollutants are found after the leakage of the device upstream of the monitor...

Abstract

The invention discloses a pollution identification and analysis method for an underground water environment, and belongs to the technical field of underground water pollution tracing. The method comprises the following steps: 1, comparing a monitoring well for discovering pollutants in the work with devices in a site, and finding out a device with the same characteristics as the discovered pollutants; 2, distinguishing the device found in the step 1 according to the upstream and the downstream of the underground water flow field of the site where the pollutant monitoring well is located; 3, calculating a time period T when the pollutants reach the monitoring well for discovering the pollutants after the upstream of the monitoring well for discovering the pollutants leaks from the device with the same characteristics as the discovered pollutants; 4, inquiring whether related operations exist in the upstream of the monitoring well with the discovered pollutants and the device with the same characteristics as the discovered pollutants before the time period T: if not, excluding the device as a seepage device; otherwise, the device is regarded as a suspected leakage device.

Description

technical field [0001] The invention relates to the technical field of groundwater pollution traceability, and more specifically relates to a pollution identification and analysis method for groundwater environments. Background technique [0002] The traceability of groundwater pollutants 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 the control of groundwater pollution. It mainly includes three aspects: tracing the release history of pollutants, determining the location of pollution sources and discharge time, and judging the distribution of pollutants in the early stage of release. The research on traceability of groundwater pollutants is helpful to formulate and select efficient and economical pollution control strategies and methods, to distinguish the responsibility of different pollution sources or pollution perpetrators, and to determine the cost o...
