Embodiment Construction

[0098] The present invention will be further described in detail below in conjunction with the examples, but the embodiments of the present invention are not limited to the scope indicated by the examples.

[0099] The method of the invention is used to evaluate the environmental risk of a sewage treatment plant in Liuzhou City, Guangxi, select environmental risk factors, and establish an index system. The relevant situation of the outlet of the sewage treatment plant is shown in Table 1:

[0100] Table 1

[0101]

[0102]

[0103] The total environmental risk value of the sewage plant is I=M+F+G=12+192+0.1+0.5=204.6, and the risk level is level II. The management requirement at this time is to strengthen the management of risk sources and make management records.

[0104] The above-mentioned embodiment scheme of the present invention is only explanation of the present invention and can not limit the present invention, has pointed out concrete parameter in the method ca...

Abstract

The invention discloses a water production and supply industry environment risk source evaluating method, which comprises the following steps: (1) selecting water production and supply industry environment risk factors including dangerous substance environmental risks, equipment and facility environmental risks and enterprise environment management risks, and computing to determine the risk value of each risk factor; (2) directly adding the risk values of the risk factors to obtain the risk value of risk sources, wherein the computing model is I=M+F+G; (3) grading the risk sources according to the risk values of the risk sources as required, and correspondingly managing the different risk grades. According to the method disclosed by the invention, dangerous substances and dangerous devices in an enterprise representing the risk levels and enterprise environment management risk level information are mainly extracted, M, F and G are used as independent variables in environment risk evaluation to establish an evaluation function, and the method has the advantages of strong adaptability, dynamic change and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of environmental risk impact assessment, and in particular relates to an environmental risk source assessment method for water production and supply industry. Background technique [0002] The water production and supply industry includes sub-sectors such as water production and supply, sewage treatment and recycling, and other water treatment, utilization and distribution. The sewage treatment and recycling industry (sewage treatment plant) is a centralized pollutant treatment facility. Since a large amount of industrial sewage and domestic sewage enter the sewage treatment plant, there are conventional pollutants such as SS, CODcr, BOD and eutrophic substances (N, P), persistent pollutants (organochlorine pesticides, polychlorinated biphenyls, etc.) and heavy metals (lead, zinc, chromium, mercury, etc.). The main environmental risk of the sewage treatment plant is the accidental discharge of sewage and th...
