Problems solved by technology

In recent years, my country has made great achievements in the research field of developing environmental risk assessment methods, but most of them focus on the point source risk assessment of industrial enterprises, or regional risk assessment systems. At present, the risk assessment of mobile risk sources in transportation still lacks scientific and reliable methods. Operational Assessment Methods

Embodiment Construction

[0041] The present invention will be further described according to the following examples, and the mode of the present invention includes but not limited to the following examples.

[0042] In this example, for city S located in the Danjiangkou Reservoir drinking water source security zone, sort out and evaluate the risk status of mobile sources, and apply this method

[0043] (1) Make road section divisions for all riverside roads and river-crossing bridges in city S, including the following steps:

[0044] S1. Whether it is a road with hazardous chemical transport vehicles, if so, execute S2, otherwise exit;

[0045] S2. Divide the passing road into independent road sections according to the pile road codes, and evaluate the subsequent steps according to the individual road sections.

[0046] There are 13 roads along the river and 56 bridges crossing the river, which are numbered as shown in the table below:

Abstract

The invention discloses a mobile source risk assessment method for an emergency environment event of a drinking water source area, and the method comprises the steps: carrying out the road segment division of a mobile source passing road, constructing a risk assessment road segment index system, and carrying out the refinement and scoring of each index; and judging the position relationship between the risk road section and the water source, obtaining the vulnerability of the water source to the mobile source, drawing a risk matrix, obtaining the risk level of the risk road section of the mobile source, and representing the risk level as the environmental risk of the mobile source running on the road section. The risk evaluation index system of the road section is constructed, the relationbetween the road section position and the water source is combined, and the risk level of the drinking water source moving source is obtained through a matrix method. According to the method, the risk of the mobile source is represented as the road section risk, and the problems of mobility and uncertainty of the mobile source in risk evaluation are solved.

Description

technical field [0001] The invention relates to the field of environmental assessment, in particular to a risk assessment method for mobile sources of sudden environmental events in drinking water sources. Background technique [0002] The source of drinking water is the basic resource that the masses rely on for survival. Its quality and safety are directly related to the health of the general public and the sustainable development of the economy and society. Ensuring the safety of drinking water is the basic requirement for safeguarding the interests of the general public. Through a series of work such as central environmental protection supervision, special environmental protection actions for drinking water sources, and spot checks on the standardized construction of drinking water sources, some prominent environmental problems that the central government paid close attention to, that were strongly reflected by the masses, and that had adverse social impacts were better r...
