摘要
以杭州市某垃圾渗滤液处理设计的两种方案比选为例,全面分析了垃圾渗滤液处理系统特点,从垃圾渗滤液处理系统的安全性、可靠性和经济性3个目标层上综合考虑,建立垃圾渗滤液处理系统的模糊综合评价模型,确定目标层、属性层的评价因素,通过专家问卷调查方式收集获得模糊判断矩阵,计算目标层、属性层、方案层的权重,实现定量评价两种系统方案的目标。模型评价结果显示:采用氧化沟的设计方案A1比采用UNITANK的设计方案A2更好,并通过已建工程应用案例验证了方案A1确实优于方案A2。对于其他类似定性且难以定量的方案比选,均可以借鉴模糊综合评价模型进行评价。目标层和属性层考虑的因素越多,计算结果越准确,但计算难度也越大。该研究所采用的将定性问题转化为定量问题的方法,不仅具有可操作性,而且具有推广使用的价值。
This study extensively analyzed the characteristics of landfill leachate treatment systems for the comparison and evaluation of design schemes.The analysis was based on two design schemes related to the landfill leachate treatment system in Hangzhou.Additionally,a fuzzy comprehensive evaluation model for landfill leachate treatment system design schemes was established,considering the three target levels of safety,reliability,and economy.The evaluation factors for the target and attribute layers were proposed after a thorough analysis.The weight coefficients for the target,attribute,and scheme layers were determined using the fuzzy comprehensive evaluation model based on a questionnaire survey of experts.The evaluation results indicated that the design scheme involving an oxidation ditch outperformed the UNITANK design in the landfill leachate treatment system.Compared with the actual engineering cases,scheme A1 was better than scheme A2.For other similar qualitative and difficult to quantify the selection of the program,it could be evaluated with the help of fuzzy comprehensive evalution model.The inclusion of multiple factors in the target and attribute layers increased the complexity of the calculation process but enhanced the accuracy of the results.The method of transforming qualitative schemes into quantitative ones,as presented in this study,is not only practical,but also widely applicable.
