中国小城镇污泥资源化方案决策方法的探讨

为了找到可以指导中国小城镇污泥资源化方案的决策方法,通过调查研究,论文确定了中国小城镇污泥处置与资源化方向的评判指标体系,综合运用层次分析法、专家评判法、熵值法确定各评判指标的权值,并采用模糊综合评判方法对中国小城镇污泥资源化方案进行决策.研究结果表明:堆肥及农用是小城镇污泥资源化的最佳方案,填埋及土地利用次之,焚烧最差.

Decision on the Program for Chinese Little Towns' Sludge Utilization

In order to get a method of decision-making in the program for Chinese little towns' sludge utilization,an index system is set up for evaluation the direction of disposal and utilization of the sludge from Chinese small town according to the result of investigation and research.In this system,Analytical Hierarchy Process(AHP),Delphi method and entropy method are comprehensively used to confirm the weight of every evaluative index,and the Fussy Comprehensive Evaluation is applied to make the decision of.The result indicates that composting and agricultural use are the best optimum for the Chinese little towns' sludge utilization,landfills and land application are the seconds,incineration is the last one.
