摘要
为了有针对性地选择污水处理工艺,以最大化发挥污水处理厂效能,采用AHP建立了4层9指标4方案的污水处理工艺综合评价体系,分别对A^2/O工艺、改良氧化沟工艺、CAST工艺和MBR工艺的技术性能、经济效益及运行管理进行了分析。4种工艺的评价体系公式计算结果分别为0.200 4,0.238 5,0.321 7和0.239 2。综合考虑各项因素对于某污水处理厂工艺决策的影响,确定CAST工艺最优,其次是改良氧化沟工艺和MBR工艺,而A^2/O为最不被推荐的工艺。
In order to select the sewage treatment process in a targeted way to maximize the energy efficiency of the sewage disposal plant,a comprehensive evaluation system for sewage treatment process including 4 layers, 9 indexes and 4 schemes was established by using AHP method, which analyzed technical performance, economic benefits and operation management of A^2/O process, improved oxidation ditch process, CAST process and MBR process.The final results showed that the formula calculation results of A^2/O, improved oxidation ditch, CAST process and MBR process were 0.200 4, 0.238 5, 0.321 7 and 0.239 2, respectively. Therefore, for a sewage treatment plant, CAST process is the most suitable sewage treatment process, followed by improved oxidation ditch and MBR process, and A^2/O is the least recommended process.
