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

Abstract

The invention discloses a method for early warning and pre-plan generation of sudden water pollution events in water transfer projects. The method first uses the DPSIR model to evaluate the overall impact of the event on the water transfer project based on the information of the sudden water pollution event, and determines the risk level of the event. , to form the first-level early warning; on this basis, use the pollutant characteristic parameter rapid prediction formula to predict the impact of the event on the water transfer target section, and form the second-level early warning. Finally, based on the early warning information, an emergency plan for sudden water pollution incidents in water transfer projects is proposed, which consists of an emergency control plan, a segmented water supply plan, and a water quality-based water supply plan after disposal. The early warning plan formed by the early warning plan method of the present invention can improve the ability of the water delivery project to deal with sudden water pollution incidents, and can provide technical support for safe and efficient water delivery, and has broad practical prospects.

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
