A method and system for assessing water environment risk in river basins for road transportation of hazardous chemicals

Abstract

The invention discloses a water environment risk assessment method for road transport of hazardous chemicals, which adopts the influence derivation method of environmental sensitive receptors, takes environmental sensitive receptors as the evaluation basis, and is based on the impact of leakage of hazardous chemicals to be transported on environmental sensitive receptors. According to the proposed hazardous chemical transportation route, several environmental risk road sections are identified, and then the environmental risk assessment and environmental risk level classification are carried out one by one, as the final plan for the hazardous chemical transportation route Auxiliary decision-making basis. The invention also discloses a water environment risk assessment system for road transportation of hazardous chemicals. Use the environmental risk assessment module to identify environmental risk receptors, environmental risk sources and environmental risk material information around the leakage path; for the risk sources identified by the environmental risk identification sub-module, based on the environmental risk source assessment method, evaluate the environmental risk level of the risk source and assist in decision-making The module realizes the prediction and simulation of sudden environmental events.

Description

technical field [0001] The invention relates to the technical field of environmental risk monitoring and treatment, in particular to a method and system for assessing the water environment risk in the road transport basin of hazardous chemicals. Background technique [0002] With the development of my country's social economy and scientific and technological level, the application of hazardous chemicals (hereinafter referred to as "hazardous chemicals") is becoming more and more extensive, and its production and transportation are also becoming more and more frequent. According to statistics, there are more than 300,000 enterprises producing, storing, transporting, selling, using, and disposing of various hazardous chemicals in my country. In 2017, my country's petrochemical and chemical industry achieved a cumulative main business income of 1.345 billion yuan, a year-on-year increase of 15.8%, an increase far exceeding the national GDP growth rate. [0003] The transportat...

Problems solved by technology

In particular, this technical solution does not take into account the degree of impact on ecological security of environmentally sensitive receptors (such as water bodies and the atmosphere) in the geographical area where each road section is located during the road transportation of hazardous chemicals from the perspective of watershed environmental protection and governance. , as well as the degree of environmental hazards, control and governance costs, etc.

[0008] Therefore, the existing technology cannot scientifically assess the impact of road leakage and other accident risks on environmentally sensitive receptors, especially the water environment of the river basin, during the transportation of hazardous chemicals to be transported from the perspective of environmental protection and emergency management. , and use this as a basic basis to screen and grade environmental risk road sections, and provide corresponding scientific assessment methods and decision-making basis for local governments, road administration departments, environmental protection management departments, traffic management departments, and managers of hazardous chemical transportation and production enterprises , in order to achieve the purpose of protecting the regional environmental safety, reducing the accident rate and the degree of environmental damage during the accident
