基于层次分析法的渗沥液处理阻垢剂选型决策研究

Study on Type Selection of LK based on Hierarchical Analysis

渗沥液处理阻垢剂选型决策涉及处理效果、产水水质、经济效益等诸多因素,其中有一些因素难以均衡选择。层次分析法具有一定的综合性,能够得到既定量化又较符合实际的评价结果。基于阻垢剂的综合指标,运用层次分析法,建立4层5指标的综合评价体系,再分别从阻垢剂处理效果、产水水质、经济效益等角度对阻垢剂进行综合评价,最终选择出最优阻垢剂。

The selection decision of scale inhibitor for leachate treatment involves the treatment effect, water quality, economic benefits and many other factors, and some of them are difficult to balance the selection. Hierarchical analysis method is a comprehensive evaluation method, which is a fuzzy comprehensive evaluation model combining quantitative and qualitative evaluation. Through the evaluation, the paper gets a both quantitative and more practical evaluation result. Based on the comprehensive index of scale inhibitor, a comprehensive evaluation system of 4 layers and 5 indexes is established, including the treatment effect, water quality and economic benefit, and the best scale inhibitor is finally selected.
