基于层次分析的高校校园排水系统优化

Optimization of Drainage System in University Campuses Based on Analytic Hierarchy Process

为找到高校校园污废水处理与处置的最佳方式,根据层次原理构建了高校校园污废水合理处理与处置层次模型。考虑到高校经济水平和中水处理的管理水平有限,且污废水的处理与处置方式影响其水资源的利用率、水费、排水管网的布置与造价、中水处理的工艺选择、布置和维护管理等,建立相应的比较矩阵,经赋值、计算,得出集中的优质废水收集处理后回用、其余污废水排入城市管网的方案。该方案的权重值为0.341,高于其他方案,因此,该方案是高校校园污废水处理与处置的最佳方案,并根据层次分析结果对高校排水系统优化提出建议。

In order to find the best way to treat and dispose wastewater in universities campuses, according to hierarchy principle, a hierarchical model of reasonable treatment and disposal of wastewater in universities campuses was constructed. In consideration of limited economic level and management of reclaimed water, and the treatment and disposal methods of wastewater affect the utilization ratio of water resources, the arrangement and cost of water fee and drainage pipelines network, as well as selection, arrangement and maintenance management of reclaimed water treatment, corresponding comparison matrix was established. After the assignment and calculation, concentrated quality wastewater was collected, treated and reused, and remaining wastewater discharged into urban pipeline network was the best scheme for the treatment and disposal of wastewater. Weight value of this scheme was 0. 341, higher than other schemes, so this scheme was the best scheme for the treatment and disposal of wastewater in colleges and universities. According to the results of AHP, suggestions were made for the optimization of drainage system in colleges.
