供水管网水质模糊评价的探讨

供水管网水质评价是供水企业了解管网运行状况和用户水质情况的重要途径.针对管网水质评价结果难以量化的问题,提出采用模糊数学评价法对管网水质进行评价.首先建立水质指标因素集和评价集,然后采用专家打分法确定权重集,根据最大隶属度原则确定评价结果,最后以我国南方某市2008年供水管网浊度测试指标为例,进行水质评价计算,结果可靠合理,客观反映了管网水质状况,从而为供水管网运行管理提供了理论依据.

Fuzzy Evaluation for Water Supply Network

Water quality assessment is an important way for the water supply enterprises to understand water quality conditions in the pipe network. In view of the problem that water quality evaluation results for pipe network are difficult to quantify, proposed with difficulty uses the fuzzy mathematics appraisal law to carry on the appraisal to the pipe network water quality. First, establishing quality indexes of factors and evaluation, and then using expert grading method to identify weight,determining the principles of evaluation results base on the principles of maximum membership. Finally take water supply network turbidity test index in a southern city, in 2008,for example,water quality evaluation calculation results are reliable and reasonable,objectively reflect the water pipe, water pipe operation management so as to provide a theoretical basis.
