Research on dynamic early-warning technology of water pollution emergency based on pollutant dispersion simulation
Considering that the flexibility and real-time of existing water environment warning system can not satisfy the increasingly severe water environment security situation and endless water pollution events, this paper put forward a dynamic early warning system structure that based on pollutant dispersion simulation, did some research on the construction of pollutant dispersion model, dynamic trigger optimization model, dynamic display of simulation results and other key techniques in detail. Take the Qiantang River in Hangzhou section for example, it used MIKE 11 series software to build the water dynamics model and the convection diffusion model, simulate the dispersion of assumed pollutants that based on the rate verification of this model and then display the functions of providing dynamic early warning services . The application shows that this system can provide accurate and convenient warning of the influence range and degree of water pollutants. It also provides decision support for relevant government departments, water companies and other enterprises to take emergency measures timely and effectively.
