Embodiment Construction

[0031] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] When an urban multi-water source raw water system encounters a sudden pollution accident, it is necessary to comprehensively judge the impact of the pollution accident on the raw water system according to the time and degree of pollution combined with the relevant parameter data of the raw water system, and evaluate the safety status of the raw water system, so as to propose appropriate and reasonable solutions. Contingency strategy or scheduling plan.

[0033] In order to achieve the above purpose of the invention, the present invention establishes the hydraulic model of the urban multi-water source raw water system on the EPANET2.0 platform, and completes the correlation coupling between the hydraulic model and the optimal scheduling mathematical model in the form of a dynamic link library. Using Matlab as the development platform o...

Abstract

The invention provides an emergency scheduling method for an urban multi-source raw water system for solving sudden pollution accidents. The method comprises the following steps of: S110, determining a spatial and temporal distribution law of water quality pollution concentration field according to a river one-dimensional water quality model of instantaneous point source, and obtaining the time when pollutant concentration at a downstream water intake section starts to exceed standard, and the length of time when the pollutant concentration exceeds standard; S120, evaluating whether the current raw water system is safe according to the data, the position of the pollution accident, the total amount of the pollutants, data of the quantity of present usable water of the raw water system and data of raw water quantity needed for a water work; S130, determining a raw water system scheduling scheme through a fuzzy inference algorithm or a predetermined optimization algorithm; S140, scheduling the raw water system according to the determined emergency strategy or scheduling scheme. With the emergency scheduling method and the system thereof for the urban multi-source raw water system, the influence of the pollution accident on the raw water system can be quickly determined under emergency condition, rational emergency strategies and optimized scheduling schemes can be determined withaims, and the safety and the reliability of the urban raw water system can be guaranteed as much as possible.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage scheduling in municipal engineering, and more particularly, to an emergency scheduling method and system for an urban multi-source raw water system in the event of a sudden pollution accident. Background technique [0002] With the sustained and rapid growth of my country's economy, various natural and man-made conflicts have led to frequent pollution accidents. Especially in the industrial-intensive areas along the southern coast, the urban water supply system is not only facing the upward impact of periodic salt tides, but also the upstream Risk of sudden pollution accidents in water sources. At present, cities mainly rely on the emergency response measures of pollution sites and water plants to deal with sudden pollution accidents in water sources. From the perspective of emergency response to pollution accidents, they are passive responses. Although such passive emergency resp...
