A risk assessment method and system for the water environment of a sudden watershed in a hazardous chemical production enterprise

Abstract

The invention discloses a risk assessment method for a sudden drainage basin water environment of a hazardous chemical production enterprise, and the method employs an environmental sensitive receptorinfluence derivation method, takes an environmental sensitive receptor as an assessment basis, and carries out the environmental risk assessment according to the influence degree of the leakage amount of substances stored or produced in an enterprise factory on the environmental sensitive receptor. And for the region with the environmental risk, determining the environmental risk level of the region in combination with the level of the environmental sensitive receptor. And further according to the provided dangerous chemical storage planning line, taking the dangerous chemical storage planning line as an auxiliary decision-making basis for finally determining a dangerous chemical storage scheme. The invention further discloses a risk assessment system for the sudden drainage basin water environment of the hazardous chemical substance production enterprise, the risk assessment system helps the enterprise to carry out daily environment risk management, early warning, environment emergency disposal and other work, and the environment risk management level is improved. And meanwhile, the prediction simulation of an emergency environment event is realized, and the environmental emergency disposal level is improved.

Description

technical field [0001] The present invention relates to the technical field of environmental risk monitoring, in particular to a risk assessment method and system for the water environment of a hazardous chemical production enterprise's emergency watershed. Background technique [0002] In recent years, with the rapid development of my country's economy, the demand for hazardous chemicals is also increasing. Followed by the continuous increase in the number of hazardous chemicals transported and the frequent occurrence of hazardous chemical accidents. Hazardous chemicals are different from ordinary goods. Due to their particularity, they are prone to accidents in the links of production, transportation, loading and unloading. Personal and property safety, the surrounding environment and public property cause huge losses. [0003] In the prior art, Chinese patent CN101931648A discloses a real-time monitoring platform for environmental risk sources in chemical industry parks...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the existing technology cannot scientifically assess the impact of accident risks such as road leakage on environmentally sensitive receptors, especially the water environment of the river basin, during the transportation of hazardous chemicals from the perspective of environmental protection and emergency management, and use this Screening and grading of environmental risk road sections as a basic basis, providing 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 to achieve protection The purpose of regional environmental safety, reducing the accident rate and the degree of environmental damage in the event of an accident
