A dangerous chemical road transportation drainage basin water environment risk assessment method and system

Abstract

The invention discloses a dangerous chemical road transportation drainage basin water environment risk assessment method, which adopts an environment sensitive receptor influence derivation method, takes an environment sensitive receptor as an assessment basis, screens an environment risk road section according to the influence degree of dangerous chemical leakage to be transported on the environment sensitive receptor, and grades the environment risk road section; identifies a plurality of environmental risk road sections according to the drafted hazardous chemical substance transportation route, and then performs the environmental risk assessment and environmental risk grade division one by one on the road sections to serve as an auxiliary decision basis for finally determining a hazardous chemical substance transportation route scheme. The invention further discloses a dangerous chemical road transportation drainage basin water environment risk assessment system. An environment riskassessment module identifies an environment risk receptor around the leakage path, an environment risk source and environment risk substance information; the risk source identified by the environmentrisk identification sub-module is evaluated on the basis of an environment risk source evaluation method, the environment risk level of the risk source is evaluated, and the decision-making module isassisted to realize the prediction simulation of the sudden environment event.

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
