Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] The technology is applied in the Yixing river network area of ​​the Taihu Lake Basin, which is located in the upper reaches of the Taihu Lake Basin and borders Taihu Lake in the east. The load of industrial wastewater in this area is relatively large. Industrial enterprises and sewage treatment plants have had accidental discharges during their operation. At the same time, there are serious phenomena of man-made illegal or leaky discharges. deterioration. Therefore, it is of great significance for the prevention and control of water pollution and eutrophication in Taihu Lake to carry out early warning and forecast in time after the sudden occurrence of routine water pollution accidents.

[0040] The present invention provides a method for real-time tracking of conventional sudden water pollution clusters under complex river network flow conditions, comprising the fo...

Abstract

The invention discloses a real-time tracking method for conventional sudden water pollution clusters under complex river network flow conditions. Based on the complex and variable hydrodynamic characteristics of the river network, the mechanism of synchronous transmission of conservative substances with water flow, and the law of pollutant migration and transformation, an integrated coupling numerical model of river network hydrodynamics, conservative substances, and water quality of conventional pollutants has been developed; through emergency accident scenarios Simulated and dynamically tracked the transmission process and path of accident wastewater and accident pollutants in the river network, obtained accident pollutants at different sensitive receptors and their corresponding conservative substance concentration process lines, and estimated the impact of accidents at different sensitive receptors response time, duration and maximum pollutant concentration. The invention can provide technical support for conventional sudden water pollution early warning and forecasting, enabling environmental managers to make timely and accurate emergency decisions, avoiding a large amount of financial and time costs, and has strong practicability and wide application sex.

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...
