The application of water quality safety evaluation for urban water supply system

摘要

The article set up a water quality safety evaluation index system on the basis of internal factors, external factors and water quality factors, through collecting and sorting of different kinds of information of Ji Nan urban water supply system. Make use of the fuzzy comprehensive evaluation methods on the basis of fuzzy mathematics and GUI in MATLAB technology for Ji Nan urban supply system's all-round evaluation. And find the potential impact factors in order to supply the management of Ji Nan urban water supply system with theoretical basis.
