摘　　要：广东某污水处理项目出水标准由一级B提升至一级A。该项目占地紧缺,需原池改造,且需要在60 d之内完成施工和通水达标。鉴于此情况,最终采用纯膜移动床生物膜反应器(MBBR)与超效分离协同的BFM(BioFilm&Magnetic)工艺,高效集约,出水CODCr、BOD5、氨氮、TN、SS、TP的均值分别为(14.0±4.2)、(2.5±0.2)、(1.1±0.9)、(10.7±2.0)、(4.1±1.4)、(0.1±0.1)mg/L,稳定达到设计标准。好氧悬浮载体实现了硝化菌的有效富集,保障了氨氮的有效去除;缺氧悬浮载体实现了反硝化菌的有效富集,保障了TN的达标排放。该污水处理升级改造项目运行电费为0.167元/m^(3),直接运行费用为0.42元/m^(3),为后期该类项目的实施提供了技术借鉴。In order to upgrade the effluent standard from level 1 B to level 1 A,a wastewater treatment plant with limit land occupation in Guangdong Province adopted the BFM(BioFilm&Magnetic)process combined of pure moving bed biofilm reactor(MBBR)and super-efficiency separation process to realize original pool reconstruction.The project implementation time is less than 60 days.In view of this situation,the BFM process of pure membrane moving bed biofilm reactor(MBBR)and super-efficient separation are finally adopted.The average effluent of CODCr,BOD5,ammonia nitrogen,TN,SS and TP is(14.0±4.2),(2.5±0.2),(1.1±0.9),(10.7±2.0),(4.1±1.4),(0.1±0.1)mg/L,respectively,and reach the designed discharge standard steadily.The project construction is rapid,and the land occupation is compact.The engineering cost is low due to the original pool reconstruction.Aerobic suspended carrier realizes the effective enrichment of nitrifying bacteria and ensures the effective removal of ammonia nitrogen.Anoxic suspended carrier realizes the effective enrichment of denitrifying bacteria and ensures the standard discharge of total nitrogen.The electricity cost of the project is 0.167 yuan/m^(3),and the direct operating cost is 0.42 yuan/m^(3),which provided a technical reference for the implementation of such projects in the future.
