| 中文摘要: |
| 采用传统的层次分析方法(Analytic Hierarchy Process, AHP)进行污水生化处理工艺的选择时,其科学性和可操作性均较低,而改进的AHP法采取三标度法,判定矩阵较易构造,且无需进行一致性检验。本研究采用改进的AHP法,建立了4层10指标4方案的污水处理工艺综合评价体系,分别对MBR、A2/O、A/O和氧化沟工艺的经济效益、环境影响及技术性能进行分析,并通过Matlab建立了污水生化处理工艺选择评价体系的公式。结果表明,MBR、A2/O、A/O和氧化沟工艺的评价体系公式计算结果分别为0.3137、0.3379、0.2085和0.1552。因此,在我国东北地区,综合考虑经济效益、环境影响及技术性能,A2/O工艺为最适宜的生化处理工艺,其次是MBR工艺和A/O工艺,而氧化沟工艺为最不推荐的工艺。由此可见,改进的AHP法可对现有污水处理工艺的经济效益、环境影响及技术性能进行直观的评价,从而为现工艺的运行管理以及新工艺的设计提供理论及实践依据。 |

| In the selection of biological wastewater treatment process, the scientificity and maneuverability of the traditional analytic hierarchy are low. 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. |
