摘　　要：针对单一因子划分污水水质等级不合理的问题,以印染废水处理厂出水水质为例,采用未确知测度评价模型对其进行综合评价,以确定其水质情况。结果表明,采用该方法得到的评价结果能够较为客观地反映污水水质等级情况,为外排污水水质评价提供了新的方法和途径,具有一定的理论意义和实用价值。未确知测度模型对评价空间实现了有序分割,提高了分辨率,评价效果可靠,是一种实用模型。Considering the unreasonableness of wastewater quality class divided by single factor, the unascertained measure model was used to assess the effluent quality from a printing and dyeing wastewater treatment plant. The results show that the assessment result can objectively reflect the wastewater quality, which provides a new method and way for assessment of discharged wastewater quality and has theoretical and practical value. Due to the ordered division of assessment space, the unascertained measure model improves distinguish level. It has reliable assessment result and is a practical model.
