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] Further illustrate the present invention by embodiment below in conjunction with accompanying drawing
[0059] 1. Screening of Air Pollution Risk Units
[0060] A survey was carried out in a city in Jiangsu, and the use, storage and disposal of toxic and hazardous chemicals were obtained from more than 30 enterprises. The maximum storage capacity of chemicals is compared, the air pollution accident risk units are initially screened, and the number of subsequent risk units to be evaluated is reduced. The filter method is:
[0061] When there is only one substance in the evaluation unit, then q i >Q i is the risk source of air pollution accidents;
[0062] When multiple substances are present in the evaluation unit, then is the risk source of air pollution accidents;
[0063] n—the type of air pollution risk substances in the unit;
[0064] q i - content of various air pollution risk chemicals, t;
[0065] Q i ——Critical value for identification of risk sources...

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 invention belongs to the technical field of environmental risk impact assessment, and in particular relates to a universal method specially used for identifying air pollution risk sources. Background technique [0002] Since 2006, there have been nearly 600 sudden air pollution accidents in my country every year, and it is gradually entering a period of high incidence 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, H 2 The S gas leakage accident resulted in 234 deaths, more than 4,000 people received medical treatment, and nearly 41,000 people were evacuated urgently; in 2005, 30 tons of liquid chlorine leaked in Huaian, resulting in 28 deaths, 350 people received treatment in the hospital, and nearly 10,000 people were evacuated. Frequent air pollution accidents not only cause...
