Pollution risk evaluation method for underground water type drinking water source region

Abstract

The invention provides a pollution risk evaluation method for an underground water type drinking water source region, wherein the pollution risk of the underground water type drinking water source region can be evaluated at a time aspect and a space aspect. The pollution risk evaluation method comprises the steps of acquiring an underground water inherent vulnerability evaluation result and a pollution source damage grade at an area with the underground water type drinking water source region; combining the underground water inherent vulnerability of the area with the pollution source damage grade, and performing preliminary evaluation on an area pollution risk; combining underground water dynamic change information with an exploitation condition on a preliminary evaluation result, thereby obtaining a water resource region pollution risk evaluation on the exploitation condition; based on the water resource region pollution risk evaluation result on the exploitation condition, combining underground water value information for performing secondary evaluation on the area pollution risk; and performing migration simulation on characteristic pollutants on the exploitation condition of the water source region based on the secondary evaluation result, thereby finishing pollution risk evaluation on the underground water type drinking water source region. The pollution risk evaluation method is suitable for the technical field of environmental science and environment risk.

Description

technical field [0001] The invention relates to the technical fields of environmental science and environmental risk, in particular to a method for evaluating the pollution risk of groundwater-type drinking water sources. Background technique [0002] In recent years, in my country, in recent years, the role of groundwater-type drinking water source pollution risk analysis technology in groundwater management and protection has become increasingly prominent, and the comprehensive application of groundwater risk assessment theories and methods has been realized. Urban scale, and for water source scale, especially large-scale centralized groundwater drinking water source, because it is in the mining state, the groundwater level and water quality are in the process of dynamic change for a long time, the pollution of groundwater drinking water source Risk assessment helps to ensure safe water supply, and the research has important scientific significance and application value. ...
