摘　　要：由于城镇小型污水处理厂工艺的选择受到很多不确定性或模糊性的信息影响,一般采用三角模糊数比较大小的评价方法进行选择。在此基础上,建立了三角模糊数和AHP(层次分析法)综合的模糊评价法,将小城镇污水处理厂工艺的选择问题的定性和定量评价综合起来。将该模型应用到工程实例中,实践证明:该方法快捷、客观、准确、实用,为城镇小型污水处理工艺方案的选择提供了科学的理论依据,具有广泛的应用前景。As selection of technology for small town sewage treatment is impacted by lots of uncertain or ambiguous information.Triangular fuzzy numbers are employed to compare big with small.This paper establishes a comprehensive fuzzy evaluation method that integrates triangular fuzzy numbers with AHP.The method offers qualitative and quantitative evaluation of the selection of technology for small town sewage treatment.It is proved that the method is fast,objective,accurate and practical,which also provides the selection of technology for small town sewage treatment with scientific and theoretical basis.So the method has a bright future.
