摘　　要：提标改造后某污水处理站处理能力为1 200 m^(3)/d,主要处理乡镇生活污水,现出水指标达到《城镇污水处理厂主要水污染物排放标准》(DB 33/2169—2018)。基于对进水水质、污水站运行状况以及运行成本等因素的综合考虑,本次改造仅将原好氧池的结构划分为好氧池1、兼氧池和好氧池2,处理系统运用AOAO(缺氧+好氧+兼氧+好氧)工艺耦合基于介质的细胞集群效应(medium-based cell cluster effect,MCCE)技术。提标改造运行结果表明,当进水水质在一定波动范围内,系统的去碳脱氮能力显著增强,具有优异的抗水质、水量冲击负荷能力,出水可稳定达到改造后设计排放标准。Treatment capacity of wastewater treatment plant(WWTP) after upgrading and reconstruction project is 1 200 m^(3)/d,it mainly deals with rural wastewater.The effluent should meet Discharge Standard of Major Water Pollutants for Municipal Wastewater Treatment Plant(DB 33/2169—2018).Based on comprehensive consideration of influent quality,operating status of WWTP and operating cost,the original aerobic pool is turned into aerobic pool 1,facultative pool and aerobic pool 2.AOAO process coupled with MCCE technique are adopted for upgrading and reconstruction project.Engineering operation results show that when the influent quality is within a certain fluctuation range,the carbon and nitrogen removal capacity of the system is significantly enhanced.Modified process has excellent resistance to water quality and water impact load,and the quality of effluent could reach up the designed discharge standards.
