Determining the weight of the evaluation index is an important prerequisite for the evaluation of advanced wastewater treatment technology in the printing and dyeing industry. The article builds an evaluation model of 10 indicators of advanced treatment technology for printing and dyeing wastewater from three aspects: environmental benefits, economic benefits, and technical performance. Furthermore, the analytic hierarchy process was used to determine the weight of each index of the evaluation system. The calculation results show that the consistency ratios of the established judgment matrices are all less than 0.1, which has a good consistency, and the hierarchical single-ranking results all meet the requirements of consistency test. Therefore, the evaluation value of the advanced treatment technology of printing and dyeing wastewater calculated by AHP is more accurate and reliable. It can provide technical support for the next step of evaluating the performance of printing and dyeing wastewater treatment.
