Abstract

The invention discloses a sudden water pollution event risk evaluation method for a water conveyance project. The method comprises the following steps: to begin with, with characteristics of the water conveyance project and characteristics of sudden water pollution events and influence thereof being taken into comprehensive consideration, and based on a DPSIR module, an index system is established, and risk evaluation indexes covering driving force, pressure, state, influence and response five aspects, index grading standard and an index calculation model are provided; a risk evaluation index weight determination method based on an analytic hierarchy process is provided; and finally, overall influence of the sudden water pollution event on the water conveyance project and risk grade are determined through a comprehensive evaluation method. The method and the risk grade evaluation result can effectively judge the influence degree of the sudden water pollution events on the water conveyance project; a more accurate risk evaluation system is established; and the method can provide decision information support for making scientific and effective early warning and preplanning of management personnel of the water conveyance project, and has wide practical prospect.

Description

technical field [0001] The invention relates to a risk assessment method for sudden water pollution incidents of water delivery projects, in particular to an evaluation method for comprehensively evaluating the impact of sudden water pollution incidents of water delivery projects on water delivery projects and the risk level based on a DPSIR model. Background technique [0002] Water transfer projects play an important role in adjusting the uneven temporal and spatial distribution of regional water resources, realizing the rational development and utilization of water resources, optimizing the allocation of water resources, solving the crisis of water resources, and meeting the needs of human production and life. Water quality safety is the key to the success of water delivery projects. In recent years, sudden water pollution incidents have occurred frequently in my country, causing relatively serious adverse effects and causing people to worry about the safety of water for ...
