Embodiment 1

[0061] figure 1 It is a flow chart of the method for grading landfill pollution risks in the embodiment of the present invention, combining figure 1 , an embodiment of the present invention provides a landfill pollution risk classification method, including:

[0062] Step S101: Obtain the basic data of multiple pollution risk grading indicators of the landfill, and calculate the correlation between the risk grading indicators according to the basic data of the risk grading indicators and the risk grading indicator evaluation system, so as to ensure the independence between the indicators;

[0063] At the beginning of landfill pollution risk grading, it is necessary to establish a risk grading index evaluation system. After the risk grading index evaluation system is established, the basic data of multiple pollution risk grading indicators of the landfill are obtained, and the risk grading index evaluation system is calculated. In order to ensure the independence of the indica...

Abstract

An embodiment of the invention provides a pollution risk grading method for a landfill site. The pollution risk grading method for the landfill site comprises the steps of obtaining basic data of multiple pollution risk grading indexes of the landfill site and calculating the correlation among the risk grading indexes according to the basic data of the risk grading indexes and a risk grading index evaluation system to ensure the independence of the indexes; determining weight values of the risk grading indexes and performing sensitive analysis on the weight values of the risk grading indexes to ensure that the weight values of the risk grading indexes are accurate; and inputting the weight values of the risk grading indexes into a multi-criteria decision analysis model to calculate a risk value of landfill site pollution so as to perform risk grading scoring of landfill site pollution. Correspondingly, an embodiment of the invention furthermore provides a pollution risk grading apparatus for the landfill site. According to the technical scheme provided by the embodiments of the invention, the groundwater pollution risk of a hazardous waste landfill site can be subjected to grading evaluation quickly and accurately, so that a risk grading result is more scientific.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of groundwater pollution risk classification from multiple pollution sources, and in particular to a method and device for landfill pollution risk classification. Background technique [0002] With the development of industry, the generation of hazardous waste is increasing day by day. According to relevant data from the National Bureau of Statistics, from 2001 to 2007, the generation of hazardous waste in my country was stable at around 1000×104t, and the growth rate has accelerated since 2008, reaching 3431×104t in 2011. In 2013, the amount of hazardous waste produced in my country showed a decreasing trend compared with 2012, but it also reached 3156×104t. Hazardous wastes contain high levels of toxic and harmful substances, which are extremely harmful to human health and the surrounding environment, and need to be disposed of safely. Safe landfill is widely used because of its adv...
