Embodiment Construction

[0046] The purpose of the present invention is to provide a statistical location method of sudden river water pollution based on a random probability model, to solve the ill-posed problem in the existing sudden river water pollution location, improve the accuracy of the correct location of the sudden pollution source, Provide accurate pollution evolution and rapid early warning information for decision-making centers.

[0047] According to one embodiment of the present invention, a statistical location method for sudden river water pollution sources based on a random probability model is provided to solve the ill-posed problem of traditional pollution location; wherein, the distribution parameter propagation equation is used for sudden river water pollution On the basis of the analysis, considering the uncertainty of the system and the sensor observation, a stochastic system model and an observation model are established; in order to solve the ill-posedness of pollution locatio...

Abstract

The invention provides a statistic positioning method for sudden river water pollution based on a random probability model. The method is characterized by comprising the following steps of: establishing a random-probability-based sudden river water pollution propagation model; establishing a random probability model for observing the sudden river water pollution concentration; and performing statistic positioning on sudden river water pollution sources.

Description

technical field [0001] The invention relates to a statistical positioning method for sudden river water pollution based on a random probability model, and belongs to the technical field of mass transfer inverse problems. Background technique [0002] Sudden surface and underground river water pollution accidents occur frequently and cause serious social harm, which is a focus of great concern to all countries in the world. For example, in 1986, more than 30 kinds of organic streams discharged from chemical plants along the Rhine River flowed into the river, causing water pollution, causing the death of a large number of aquatic organisms, and affecting the lives and production of millions of people in four countries on both sides of the Rhine River; The pollution incident led to a three-day water cut in Harbin and attracted the attention of the governments of China and Russia. In addition, once underground rivers are polluted, the consequences are even more dire. Treatment...
