Embodiment 1

[0062] Such as figure 1 As shown, the embodiment of the present invention provides a method for early warning and emergency treatment of sudden water pollution incidents in the basin, including the following steps:

[0063] S1, obtain the current water quality parameters and pollutant concentrations of the water body in each monitoring area of ​​the watershed, and judge whether the current sudden water pollution event occurs in the watershed, if it occurs, execute S2, otherwise, enter the next cycle;

[0064] S2, normalize the water quality parameters and pollutant concentrations of the current sudden water pollution incident, obtain dimensionless water quality parameters and pollutant concentrations, and obtain an index set X reflecting the pollution status of the current sudden water pollution incident;

[0065] S3, obtain the water quality parameters and pollutant concentrations of each sudden water pollution incident recorded in history, and perform normalization processin...

Embodiment 2

[0126] Such as figure 2As shown, the method for early warning and emergency response to watershed sudden water pollution incidents provided by the embodiments of the present invention further includes steps between S5 and S6:

[0127] Statistically test the X obtained in S2 and the Y obtained in S3, and judge whether there are historical sudden water pollution incidents similar to the current sudden water pollution incident according to the test results. The closest historical water pollution incident, and according to the disposal plan of the closest historical water pollution incident and the specific characteristics of the current sudden water pollution incident, the emergency treatment plan for the current sudden water pollution incident is obtained; otherwise, Execute S6.

[0128] Among them, the statistical test of X obtained in S2 and Y obtained in S3 can be performed by a non-parametric test method, specifically, a signed rank sum test method of two independent sampl...

Embodiment 3

[0131] Such as image 3 As shown, the embodiment of the present invention provides an early warning and emergency response system for watershed sudden water pollution incidents, including:

[0132] Historical data storage module: used to store the water area overview, hydrological information, water quality parameters, pollutant types and concentrations, characteristic pollutant diffusion methods, pollution levels and emergency response plans of the places where historical sudden water pollution incidents occurred;

[0133] Historical data preprocessing module: used to classify historical sudden water pollution events, and normalize and standardize the information of historical sudden water pollution events;

[0134] Real-time data acquisition module: used to obtain real-time monitoring data of water quality parameters and pollutant concentrations in the basin by using automatic water quality monitoring stations and pollutant online monitoring system monitoring equipment;

Abstract

The invention discloses a sudden water pollution accident warning and emergency disposal method and a sudden water pollution accident warning and emergency disposal system, and belongs to the field of water environment monitoring, warning and emergency disposal. According to the method, a typical pollutant is identified according to the type, concentration, main water quality parameters and other indexes of the pollutant, a sudden water pollution accident is classified, the sudden water pollution accident is verified by comparing the pollution indexes of the sudden water pollution accident with the pollution indexes of the most serious sudden water pollution accident of the corresponding type in history, the level of pollution of the sudden water pollution accident is determined according to the verification result, and an emergency disposal system of the corresponding level is started according to different levels of pollution to obtain a corresponding disposal scheme. As disposal resources and schemes of corresponding levels are adopted for sudden water pollution accidents of different levels, reasonable utilization of various emergency resources is ensured, and a disposal scheme can be obtained quickly. Moreover, inadequate response or excessive response after the occurrence of a sudden water pollution accident is avoided, effective warning for a drainage basin sudden water pollution accident is realized, and the damage caused by sudden water pollution incidents is reduced greatly.

Description

technical field [0001] The invention belongs to the field of water environment monitoring and early warning and emergency treatment of sudden water pollution incidents, and relates to a method and system for early warning and emergency treatment of sudden water pollution incidents, in particular to a rapid classification and emergency response to pollution levels of sudden water pollution incidents A method and system for quickly obtaining a disposal plan. Background technique [0002] Watershed is a kind of complex natural geographical area, which is a comprehensive ecology that closely connects natural supporting systems such as water cycle, land cover and ecosystem in a specific area with surface water and groundwater as the main link, and social and economic systems such as population, economy and society. territory system. [0003] Compared with general water pollution problems, sudden water pollution incidents have the characteristics of uncertainty and randomness, su...
