Near-river water source water quality pre-warning method based on groundwater pollution risk evaluation

Abstract

A near-river water source water quality pre-warning method based on groundwater pollution risk evaluation of the invention comprises the following steps: calculating the groundwater pollution risk to a study region of near-river water source water quality pre-warning, risk-zoning the study region according to the calculation result, and getting pollution risk evaluation; selecting pre-warning influence factors of a near-river water source; respectively giving preset risk weights to the pollution risk evaluation and the pre-warning influence factors; and calculating near-river water source water quality pre-warning zones according to the pollution risk evaluation and the pre-warning influence factors and the risk weights thereof. The method is implemented with the aid of a pollution risk evaluation system. The regional environment risk and the dynamic change in the quality of groundwater under mining conditions are superposed and coupled in a water source protection region to get pre-warning zones. The purpose of comprehensive prevention and control is achieved. Through water source water quality pre-warning from a macroscopic perspective, the quality of water can be guaranteed more scientifically, reasonably, comprehensively and effectively on the premise of understanding the environmental condition of a water source and the surrounding region thereof.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and water quality safety, and in particular relates to a water quality safety early warning method for water sources near rivers based on groundwater pollution risk assessment. Background technique [0002] Early warning of water quality safety in water source areas aims to ensure water quality safety. By proposing early warning measures to reduce the possibility of water source areas being harmed or by formulating a number of possible incidents that may cause harm to water source areas in advance, the management and control of water quality safety in water source areas is achieved. Through a series of early warning means, according to the conditions represented by the water source and its surroundings, the warning forecast is carried out to eliminate the hidden dangers of early warning.

AI Technical Summary

Problems solved by technology

[0003] Usually, early warning of water quality safety is carried out through real-time monitoring of water quality or simulation of water quality change trends, but the above two methods cannot provide overall early warning from the catchment area of ​​the water source to the discharge area, and cannot achieve the purpose of comprehensive prevention and control. Unable to serve the comprehensive management of water resources in water source protection areas and areas where water sources are located

At present, there is a lack of methods for early warning of water quality safety in water sources from a macro perspective
