Real-time tracking method for conventional sudden water pollution group under complex river network water flow condition

Abstract

The invention discloses a real-time tracking method for a conventional sudden water pollution group under a complex river network water flow condition. A river network hydrodynamic, conservative substance and conventional pollutant water quality integrated coupling numerical model is developed on the basis of complex and changeable river network hydrodynamic characteristics, a conservative substance and water flow synchronous transmission mechanism and a pollutant migration and transformation rule. Through sudden accident scene simulation, the transmission process and path of accident wastewater and accident pollutants in a river network are dynamically tracked, accident pollutants at different sensitive receptors and corresponding conservative substance concentration process lines are obtained, and the reaction time, duration and maximum pollutant concentration of accident influences at different sensitive receptors are estimated. Technical support can be provided for conventional sudden water pollution early warning and forecasting, so that an environment manager can timely and accurately make an emergency decision, consumption of a large amount of financial cost and time cost isavoided, and the method has very high practicability and wide applicability.

Description

technical field [0001] The invention relates to a real-time tracking method for conventional sudden water pollution clusters under complex river network flow conditions, belonging to the field of water environment health risks. Background technique [0002] In recent years, there have been many major water pollution accidents around the world, which have seriously threatened human health and life safety, caused huge economic losses, social instability and serious damage to the ecological environment, and even caused international disputes. One of the environmental problems. Due to the uncertainty and unpredictability of sudden water pollution accidents, we can only effectively prevent and actively respond to them. Early warning technology is a powerful means to scientifically determine risk changes, improve emergency response levels, and avoid pollution risks. Therefore, it has become a hot spot that domestic and foreign water environment experts and scholars have been payi...
