Abstract The cleaner production grade evaluation problem of wastewater treatment plants was studied through the method of combining qualitative analysis with quantitive computation. The index system of cleaner production grade evaluation for urban sewage treatment plants and corresponding weights’ determination method were proposed. The fuzzy comprehensive model of the cleaner production grade evaluation for town sewage treatment plants was established and the two-tuple semantic model and method through introducing the concept of the grade eigenvalue were developed through using the linear weighted comprehensive method, fuzzy mathematics and the concept of two-tuple semantic. It was illustrated with a real example that the established two-tuple semantic model and method of the cleaner production grade evaluation were more operational, intuitionistic and easily explained. Thus, the two-tuple semantic model and method proposed in this paper were of good applicability and generalization value.
