Embodiment Construction

[0072] Taking a certain area in North China as an example, the study area is 30-100 meters above sea level, located between the first terrace, the second terrace and the loose sediments of the Quaternary landform. The geodetic structure within the jurisdiction belongs to the border zone between the Shanxi Platform and the Bohai Sag. The terrain is low in the east and high in the west, and the landform is complex. The landforms are arranged in sequence from west to east as middle mountains, low mountains, hills, basins, and plains. Atmospheric precipitation is the main supply source, and underground runoff, artificial mining and evaporation are the main excretion methods. to combine Figure 1 to Figure 8 As shown, a method for identifying potential groundwater pollution risk sources is further described, in which figure 1 To identify the technical route of potential pollution risk sources, the specific steps are as follows:

[0073] Step 1. Collect the types of potential pol...

Abstract

The invention discloses a method for identifying potential pollution risk sources of underground water. The method comprises the following specific steps: 1, dividing six types of potential pollutionrisk sources; 2, determining the weights of toxicity, mobility and degradability of the characteristic pollutants, and determining the harmfulness of the characteristic pollutants; 3, establishing a pollution risk source pollutant discharge amount calculation model, and comprehensively determining the harmfulness of the risk source; 4, establishing risk source occurrence condition evaluation indexgrading; 5, establishing a risk source contribution rate model, and calculating the intensity of the potential pollution risk source; and 6, grading contribution rates of various potential pollutionrisk sources. The key identification range of the potential pollution risk source in the research area can be determined; the harmfulness level of the characteristic pollutants can be recognized, andtargeted prevention and control are achieved; comprehensive evaluation of harmfulness of a pollution source is facilitated, and six types of pollution risk sources are comprehensively managed and controlled; through the risk contribution rate of each pollution source in different areas, targeted prevention and control measures and schemes are provided.

Description

technical field [0001] The invention belongs to the technical field of groundwater pollution protection, in particular to a method for identifying potential groundwater pollution risk sources. Background technique [0002] Groundwater is an important part of the water cycle, an important source of water supply for cities in our country, and one of the important sources of medical water. With the increasing development of resources, its pollution is becoming more and more serious, such as pollution by agricultural non-point sources and urban rainwater runoff, urban industrial waste water pollution, landfill leakage pollution, mining wastewater leakage pollution, etc., resulting in greater groundwater resources. Therefore, identification of potential risk sources of groundwater has a certain preventive and protective effect on the protection of groundwater. [0003] Usually, when considering the evaluation of regional groundwater risk, the process analysis method is often use...
