Problems solved by technology

[0005] The invention provides a practical method for identifying risk sources of air pollution accidents. Aiming at the problems of poor pertinence, low precision, and inability to effectively identify risk sources of air pollution accidents in previous methods for identifying risk sources of air pollution accidents, a method based on accident process simulation, The method for identifying risk sources of air pollution accidents with strong universality can calculate the risk value of air pollution risk sources by applying the technology of the present invention, and quantitatively grade them, providing a technical method for avoiding and emergency response to sudden air pollution accidents

Embodiment Construction

[0058] The present invention will be further explained by the following examples in combination with the drawings

[0059] 1. Screening of air pollution risk units

[0060] A survey was carried out for a city in Jiangsu, and the use, storage, treatment and disposal of toxic and hazardous chemicals in more than 30 companies were obtained. Based on the identification threshold of environmental pollution accident risk sources (see Table 1), it passed the assessment of the toxic and hazardous risks in the unit to be evaluated. The maximum storage capacity of chemicals is compared, and the risk units of air pollution accidents are initially screened, and the number of risk units to be assessed in the future is reduced. The screening method is:

[0061] When there is only one substance in the evaluation unit, then q i >Q i Time is the risk source of air pollution accidents;

[0062] When there are multiple substances in the evaluation unit, then Time is the risk source of air pollution ac...

Abstract

The invention discloses an identification method of atmosphere pollution risk source based on the analysis of accident overall process, which comprises the following steps that: (1) critical value is identified according to environmental pollution accident risk source, and an atmosphere pollution accident risk unit is preliminarily selected; (2) maximum credible accident source intensity of the atmosphere pollution is determined; (3) accident danger range of risk source is calculated; (4) harmful consequences such as personnel injury, public scare, ecological loss and the like caused by the atmosphere pollution risk source is evaluated; (5) comprehensive harmful consequence of the atmosphere environmental pollution accident is normalized and superposed; (6) risk value of atmosphere pollution accident risk source is calculated; (7) grade of atmosphere pollution accident risk source is determined. The method solves the problems of the traditional environmental pollution accident risk source identification method that the pertinence is poor, the precision is low, the risk level of the atmosphere pollution accident cannot be effectively determined, and the like, establishes an atmosphere pollution accident risk source identification method based on the analysis of the accident overall process which has strong universality, and provides a technical method for the circumvention and emergency of atmosphere pollution accident.

Description

Technical field [0001] The present invention belongs to the technical field of environmental risk impact assessment, and specifically relates to a universal method dedicated to the identification of air pollution risk sources. Background technique [0002] Since 2006, my country has had nearly 600 sudden air pollution accidents every year, and it is gradually entering a period of high occurrence of sudden air pollution accidents. Unlike other environmental pollution accidents, air pollution spreads quickly and is difficult to control, often causing serious losses in a short period of time. For example, in 2003, the H 2 The S gas leak caused 234 deaths, more than 4,000 people were treated, and nearly 41,000 people were evacuated. In 2005, 30 tons of liquid chlorine leaked in Huai'an, resulting in 28 deaths, 350 people were treated in hospitals, and nearly 10,000 people were evacuated. Frequent air pollution accidents have not only caused a large number of casualties, but also cau...
