高校中水水源分类及基于AHP方法的优质度排序

Classification of Universities'Reclaimed Water Source and Sorting of Exploitability Based on AHP Method

高校是我国城市用水大户,在高校校园建立中水回用系统是节约水资源、减少水污染、建设生态校园的有效途径,选择优质的中水水源是保证中水回用系统高效运行的首要前提。目前,开辟中水水源多基于简单定性分析后加以利用,少有对水源的量化评价以及优质度的排序。文章针对高校中各个单位用水类型不同、排水水质和水量呈多样性的问题,将校园内各个水源进行综合分类并运用层次分析法(AHP)进行优质度的量化评价,以各水源优质程度排序为依据筛选出可利用的中水水源。根据实地调查及实验分析数据,以北京师范大学为例应用评价方法,并将结果与校园实际的中水回用情况对比,验证指标及方法的合理性。文章将为高校中水水源的分类及筛选的量化评价提供借鉴。

Universities are big water users in China.To establish water reuse system is effective to protect water source,reduce water pollution and construct an ecological campus.Selection of high quality reuse water proved to be basic premise in order to operate reusing system efficiently.Selection of reclaimed water sources is always after a simple qualitative analysis rather than a quantitative evaluation.Aiming at questions of difference in water quality and quantity,reclaimed water source were classified and sor...
