摘　　要：本文首先对广泛应用于污水处理领域的A^(2)/O和A/O两种生物处理工艺进行了分析,随后以吉林省某地区实际运营的生化处理工艺分别为A^(2)/O和A/O工艺的两家污水处理厂进行了分析,对两种工艺的主要构筑物和机电设备进行了对比,最后,以处理1万m^(3)/d污水为基准,研究了两种工艺的生命周期评价清单,结果表明,在污水处理的各个环节中,A^(2)/O工艺由于其独特的结构设计和反应机制,展现出较A/O工艺更高的处理效率和更低的环境负担。This paper first analyzes two widely used biological treatment processes,A^(2)/O and A/O,in the field of wastewater treatment.It then evaluates two wastewater treatment plants in a specific area of Jilin Province that operate using A^(2)/O and A/O processes,comparing the main structures and electromechanical equipment of both systems.Finally,based on the treatment of 10,000 m^(3)/d of wastewater,this study investigates the life cycle assessment inventories of the two processes.The results indicate that the A^(2)/O process,due to its unique structural design and reaction mechanism,exhibits higher treatment efficiency and lower environmental burden compared to the A/O process at various stages of wastewater treatment.
