The improved AHP method adopts three scale method, and the judgment matrix is easy to construct; furthermore, there is no need to check the consistency. In the present study, the improved AHP was applied to establish a comprehensive evaluation system with four layers, 10 indexes and four schemes. The comprehensive evaluation system was employed to analyze the economic benefits, the environmental impacts and the technical performance of four wastewater treatment process, i.e., MBR, A2/O, A/O and oxidation ditch process. The weight of each factors was calculated by Matlab software. Then the overall weights of the ten special was acquired by multiplying the weights of the general indexes and the 10 special indexes. Finally, the evaluation formula for the selection of the wastewater treatment process was established by multiplying the overall weights and the weights of the four processed. The calculated results of the evaluation formula for MBR, A2/O, A/O and oxidation ditch process were 0.3137, 0.3379, 0.2085 and 0.1552, respectively. Therefore, comprehensively considering the economic benefits, the environmental impacts and the technical performance, A2/O is the most suitable biological wastewater treatment process for Northeast China, followed by the MBR process and A/O process, and oxidation ditch is the least recommended process. In conclusion, the improved AHP method could make a direct evaluation on the economic benefits, the environmental impacts and the technical performance of the current wastewater treatment process, which could provide theoretical and practical basis for the operation and management of the current process and the design of new process. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
