Embodiment Construction

[0063] The present invention will be further described below by way of examples in conjunction with the accompanying drawings.

[0064] 1. Analysis of the most likely accident type

[0065] Based on an on-site investigation in a city in Jiangsu, the daily use, storage and disposal of toxic, hazardous and dangerous chemicals in more than 30 enterprises were obtained. Based on the critical value specification for the identification of water pollution accident risk sources, the screening of potential water environment pollution risk units was carried out, and 16 enterprises with potential water pollution accident risk sources were initially screened out. This example carries out the identification of water pollution accident risk sources for 5 typical enterprises, and the analysis results of the most likely accident types are shown in Table 1.

Abstract

The invention discloses practical technology used for water pollution accident risk source recognition. The technology comprises the following steps of: (1) analyzing maximum probable accident types; (2) determining maximum credible accident source intensity of the water pollution; (3) calculating a comprehensive damage result of an accident; (4) calculating accident type difference and case statistics-based emergent accident probability; and (5) quantifying the water pollution accident risk source level. Aiming at the problems that the current environmental risk source recognition method is coarse and has poor pertinence, and the like, the invention establishes a water pollution accident risk source recognition method with strong adaptability, dynamic change and high accuracy. The technology can calculate the risk value of the water pollution accident risk source, determine the risk level and the maximum credible accident level, and provide technical support for normalized management and emergence of the emergent water environmental pollution accident.

Description

technical field [0001] The invention belongs to the technical field of environmental risk impact assessment, and in particular relates to a method with strong universality, which is mainly used for identifying risk sources of surface water pollution accidents. Background technique [0002] In recent years, my country has gradually entered a period of intensive and high incidence of sudden water pollution incidents. Statistics show that since 2006, there has been an environmental accident every two days in my country on average, of which 70% are water pollution accidents. Sudden water pollution accidents have become an important factor that endangers human health and destroys the ecological environment, and seriously threatens the harmonious development of our country's environment, economy and society. For example, the Songhua River nitrobenzene pollution accident in 2005 caused more than 3 million people to have difficulty drinking water; the 2008 arsenic-containing wastewa...
