Pollutant migration simulation-based water source site water quality safety early warning method

Abstract

The present invention provides a pollutant migration simulation-based water source site water quality safety early warning method. The method includes the following steps that: a water flow model is constructed; the target pollutant of a water source site is determined; the migration model of the target pollutant in a water containing layer is constructed according to the water flow model; the simulation time of the migration model is preset, the migration and distribution result of the target pollutant is obtained; and early warning judgment is performed according to the migration and distribution result and an early warning level. According to the pollutant migration simulation-based water source site water quality safety early warning method, based on the pollutant migration simulation of a monitoring result and water source hydrogeological parameters, a pollution source condition is simulated, and a characteristic pollutant distribution condition is obtained, for example, ammonia nitrogen of farmlands in the Li Min economic development zone in Harbin of Heilongjiang Province will not pose a threat to the safety of water quality in Limin water sources in 20 years, and the initiative of water quality safety early warning work in water source sites near rivers can be improved, and management on the water source sites and prejudgment on pollution situations can be facilitated.

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 source water quality safety early warning method based on pollutant migration simulation. Background technique [0002] Water quality safety early warning can reduce the investment in water quality monitoring and water quality safety assurance, and at the same time reduce the harm caused by sudden water quality accidents. Because there is a close hydraulic connection between the groundwater and the river in the water source area near the river, and the river is often polluted by sewage or sudden water quality accidents, it will inevitably threaten the water quality safety of the riverside water. , you can take response measures at the first time of the accident to minimize the losses caused by the accident. [0003] Water quality safety early warning technology usually includes early warning based on water quality sta...

Problems solved by technology

[0004] At present, there is no water quality predictive modeling method that can be widely applied. Therefore, there is still a long way to go before the water quality safety warning through the method of water quality predictive modeling.
