新疆军区部队生活饮用水水质的模糊数学评价

APPLICATION OF FUZZY MATHEMATICS TO EVALUATION OF DRINKING WATER QUALITY IN THE ARMY OF XINJIANG MILITARY COMMAND

目的应用模糊数学对新疆军区某部队生活饮用水水质进行综合评价,使其结果更加科学和客观,为新疆军区部队饮水安全管理提供科学依据。方法在现场调查和实验室检测的基础上,选择12个检测项目作为综合评价指标。建立模糊数学模型对新疆军区某部生活饮用水水质进行模糊综合评价。结果所调查部队生活饮用水水质类别以Ⅱ类为主,但少部分部队生活饮用水的溶解性总固体、总硬度、硝酸盐氮、氟化物、菌落总数和总大肠菌群等较高,归为Ⅲ类。结论新疆军区某部队生活饮用水水质总体上良好,但少部分部队生活饮用水存在安全隐患,应加强监管。模糊数学评价方法可客观、综合评价水质情况,具有较好的实用价值。

Objective Fuzzy mathematics was introduced to comprehensive evaluation of water quality in order to get more scientific and objective results, so as to provide a scientific basis for hygienic safety management of drinking water of the army in Xinjiang military command. Methods On the basis of field investigations and labo- ratory tests, 12 detecting items were selected as comprehensive evaluation indexes. Then a fuzzy mathematical mod- el was established to evaluate the quality of drinking water of an army in Xinjiang military command. Results The quality of drinking water in most of the army belonged to category II. However, the total soluble solids, total hard- ness ,level of NO3^--N and F-,total number of bacterial colony,and E coli colony in some of the army were relatively high（belonged to category III ）. Conclusion The fuzzy mathematics evaluation is an objective and comprehensive method for assessing the quality of drinking water and has practical value. In general, the quality of drinking water in the army in Xinjiang military command is good, but some have hygienic safety risks, therefore it is necessary to strengthen the supervision.
