Embodiment Construction

[0047] Such as figure 1 Shown, groundwater quality comprehensive evaluation method of the present invention comprises the following steps:

[0048] a. Reclassify groundwater quality indicators in manganese, fluoride, iodide, mercury, arsenic, selenium, lead, beryllium, nickel, cobalt, thallium, volatile phenol, 1,1,2-trichloroethane, 1,2- Classification cut-off values ​​of seventeen water quality indicators for dichloropropane, vinyl chloride, benzo(a)pyrene, and polychlorinated biphenyls.

[0049] b. Select the participating water quality indicators according to the groundwater sample test indicators, and substitute the test results of the groundwater samples and the classification boundary values ​​of the selected participating water quality indicators into the membership function to calculate the fuzzy membership degree matrix.

[0050] c. Perform data conversion on the toxicity index of the water quality index.

[0051] d. Calculate the weight matrix according to the co...

Abstract

The invention relates to a comprehensive evaluation method of underground water, wherein the method includes steps of a, re-classifying the classification dividing value of seventeen water quality indexes such as manganese, fluoride, monoiodide and mercury in the underground water quality; b, selecting the water quality index participated in rating according to the testing index of the underground water sample, and substituting the testing result of the underground water sample and the classification dividing value of the selected water quality index participated in the evaluation to a membership function, and calculating and acquiring a fuzzy membership matrix; c, performing data conversion on a toxic index of the water quality index; d, according to the converted toxic index, the sample testing result, and the classification dividing value of the water quality index, calculating a weight matrix; e, coupling the fuzzy membership matrix with the weight matrix, and acquiring the evaluation result matrix and the evaluation grade of the underground water quality. The evaluation result fully considers about the risk of the human body health, and can comprehensively evaluate the underground water quality from the view of the human body health risk; the evaluation result can further objectively reflect the drinking safety.

Description

technical field [0001] The invention relates to a groundwater evaluation method, in particular to a groundwater quality comprehensive evaluation method. Background technique [0002] Groundwater is a very important drinking water resource, which plays an irreplaceable role in supporting the healthy development of the economy and society. Its quality status will directly affect human health. As a direct water supply source in many areas, groundwater quality evaluation is very necessary from the perspective of drinking water safety. [0003] The water quality evaluation process is mainly based on the analysis of the water chemical data of the sample points, and the analysis covers conventional indicators and toxicological indicators. Compared with conventional indicators, toxicological indicators are more important to human health. Therefore, in the evaluation process, it is necessary to distinguish conventional indicators from toxicological indicators to better reflect the...
