Early warning and plan generating method for sudden water pollution event of water conveyance project

Abstract

The invention discloses an early warning and plan generating method for a sudden water pollution event of a water conveyance project. The method comprises the following steps: first, based on sudden water pollution event information, using a DPSIR model to evaluate the overall impact of the event on a water conveyance project, judging the risk level of the event, and forming a first-level early warning; on the basis, pre-judging the impact of the event on the section of a water conveyance target according to a pollutant characteristic parameter fast prediction formula, and forming a second-level early warning; and finally, based on the early warning information, putting forward a water conveyance project sudden water pollution event emergency plan composed of an emergency control scheme, a segmented water supply scheme and a disposed water body quality-divided water supply scheme. By using an early warning plan formed by the early warning and plan generating method of the invention, the ability of water conveyance projects to deal with sudden water pollution events is improved. A technical support is provided for safe and efficient water conveyance. The early warning and plan generating method has a broad practical prospect.

Description

technical field [0001] The invention relates to a method for early warning and preplan generation of sudden water pollution incidents in water delivery projects, in particular to a two-level early warning for sudden water pollution incidents in water delivery projects, and includes emergency control schemes, segmental water supply schemes, and quality-based water supply schemes A method for generating emergency response plans. Background technique [0002] The safety of water quality in water delivery is an important guarantee for the effectiveness of water delivery projects. Sudden water pollution incidents of water transmission projects have the characteristics of sudden occurrence, multiple sudden channels, complex types of pollutants, and impact on water transmission guarantee rate and shipping. This makes the control of polluted water bodies more difficult. At present, there are many studies on the prediction and early warning of sudden water pollution incidents in na...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved in the present invention is that the early warning indicators for sudden water pollution events are single and there is no early warning method suitable for water delivery projects, and the impact of events on water delivery projects and water delivery target sections is not comprehensively considered; at the same time, the existing The generation method of emergency response measures is poorly targeted, and is mainly a management plan at the macro system level, so it is difficult to quickly and reasonably formulate an emergency plan that can guide decision makers to operate; based on this, the present invention provides a water delivery project emergency Early warning and plan generation method for water pollution incidents
