Comprehensive evaluation method of underground water

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...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a comprehensive evaluation method for groundwater quality to solve the problem that the existing groundwater quality evaluation method cannot reflect the toxicity difference of water quality indicators in the water quality evaluation results, which leads to the inconsistency between the evaluation results and the objective situation.
